Choosing an archival file format for family photos is less about finding one perfect extension than protecting the best version you have. Here’s when to use TIFF, JPEG or PNG—and how to keep the people and stories in each picture identifiable.
A box of family photographs can raise two questions at once: How do you scan these pictures without losing detail, and how will anyone know what they show years from now? File format addresses the first question, but not the second. A beautifully scanned photograph labeled IMG _0042 can still become a mystery.
For most families, a sensible approach is to keep the best available original or scan, make convenient copies for viewing and sharing, and record the context that gives each image meaning. That may mean a TIFF master and a JPEG sharing copy for a newly scanned print. It may mean keeping a camera-original JPEG exactly as it is. And it may mean choosing PNG when the image contains text or graphics that need crisp edges.
The good news is that you do not need to convert your entire collection into one format. You need a workable way to decide what to preserve, what to use day to day, and where to tell the stories that files cannot tell on their own.
TIFF, JPEG and PNG can all hold an image, but they make different trade-offs in file size, compression and everyday usability. The Library of Congress lists all three among its preferred formats for digital photographs; that does not mean they are interchangeable for every family-archiving task. The quality of the source image and the way a particular file was created still matter.[17]

H3: TIFF: A strong choice for new master scans
If you are scanning a treasured print and have room to store a substantial file, TIFF is a practical choice for the master. An uncompressed TIFF preserves the image data captured by the scanner, while TIFF can also use lossless options such as LZW compression. Uncompressed TIFF has been widely used as a master format in digital-library work.[37][52]
That does not make a TIFF automatically better than its source. Saving a small, heavily compressed JPEG as a TIFF will not restore detail that was already discarded. Likewise, scanning at an impressive setting cannot invent detail absent from a faded or blurry print. TIFF is most useful when you choose it at capture , or when you need a working format that avoids further lossy compression during editing.
Keep a master scan separate from the copies you crop, brighten or send to relatives. A descriptive name such as 1978 _family _picnic _original _scan.tif helps distinguish it from later versions. You can then make a JPEG for convenient viewing without asking one file to serve every purpose.
Give them the home they deserve. Bring your family legacy into the digital age.
Start archivingH3: JPEG: Keep the original, even though compression is lossy
Most families already have many photographs as JPEGs. There is no reason to treat those pictures as failures of preservation. JPEG is convenient for viewing and sharing, and the Library of Congress includes JPEG/JFIF among its preferred digital-photograph formats. The common JPEG compression used for photographs is lossy, however: saving an image with that compression discards some image information.[17][49]
The important distinction is between keeping an existing JPEG and repeatedly replacing it with newly compressed versions . If the highest-quality copy of your father’s birthday photograph is a JPEG straight from a camera, preserve that file. Do not convert it to TIFF in the hope of improving it, and do not overwrite it each time you edit. Make a separate copy for adjustments.
JPEG is also a useful companion to a TIFF master. It makes a scanned family photograph easier to open on ordinary devices and share with someone who can identify the people in it. The master remains available if you later want to make a different crop or print.
H3: PNG: Useful when crisp detail matters
PNG uses lossless compression and supports photographic images as well as graphics. It can be particularly useful for an image that mixes a photograph with legible text, a family-tree graphic, or another element with sharp lines. The format also supports features such as transparency, although most scanned family prints do not need it.[40]
PNG is not automatically the best choice for every photograph. A lossless PNG made from an already-compressed JPEG cannot recover the JPEG’s missing information. For a collection of ordinary camera photos, keeping the original JPEGs is generally more useful than creating PNG duplicates simply because “lossless” sounds safer. Reserve PNG for a clear purpose—such as preserving a newly created image with text or avoiding lossy compression in a particular workflow.
H2: How to choose an archival file format for family photos
The simplest decision rule is to ask where the image came from and what you plan to do with it . A photograph you are scanning today offers choices that a camera JPEG from twenty years ago does not. In either case, the best available version deserves protection.
For a new scan of an important print , save a high-quality TIFF master if your scanner and storage allow it. Make a JPEG copy for everyday access. If you can only scan to a high-quality JPEG, scan and preserve it rather than postponing the project indefinitely. Capturing an identifiable photograph and its story is more valuable than waiting for a technically perfect setup.
For an existing digital photograph , retain the original file from the camera or device whenever possible. If you find several copies, compare their pixel dimensions, appearance and provenance before deleting anything. A small image downloaded from a social post may look similar on a phone but be a poorer source than the original file. The Library of Congress advises keeping the highest-quality version when multiple versions of an important photo exist.[4]
For a photograph containing handwriting or other annotations , capture the information as well as the picture. If writing appears on the back of a print, scan or photograph the back and give both files matching identifiers. A lossless master may help preserve fine details, but a short transcription is useful too—especially if the handwriting is faint. When the original is fragile, handle it carefully rather than forcing it onto a scanner; the U.S. National Archives recommends retaining physical originals after digitization because digital files have preservation risks of their own.[13]
Consider an unlabeled wedding photo and a nearly identical print with names written on the reverse. The second print may be the better archival starting point even if its image is slightly worn. Scan the front, capture the back, and record who supplied the identification. Format matters, but so does the evidence that turns a photograph into family history.
H3: Choose scan settings for the original, not for a magic number
Resolution matters when making a scan, but there is no single setting that fits every print and every intended use. Guidance published by American Ancestors recommends at least 400 pixels per inch for photographs measuring 8 × 10 inches or less, with attention to the resulting pixel dimensions; it gives different recommendations for larger photographs and film. Film also requires suitable scanning equipment.[11]
For a home project, first make sure the entire print is captured, including any borders that help document it. Preview the scan, check focus and exposure, and avoid relying on software enlargement as a substitute for a detailed capture. If you are unsure which settings to use, test one representative photograph, open the resulting file at full size, and check whether faces and writing are clear before scanning a whole album.
Do not put a fragile, oversized or firmly mounted original at risk to meet an ideal setting. The U.S. National Archives cautions that a scanner lid can damage an item that does not fit fully on the glass.[13]
H2: Build an archive that preserves meaning, not just pixels
A folder named Old Photos is a beginning, not a finished personal archive. It may contain excellent files, yet leave your children guessing who is pictured, when the photograph was taken, or why it was kept. The format can preserve image data; the family has to preserve the explanation.
Start with a manageable selection rather than trying to describe thousands of images at once. Choose a few photographs that represent important people, places or moments. For each one, record what you know and distinguish it from what you suspect:
Create a digital legacy that your children and grandchildren will be proud of.
Create a family legacyGive files descriptive names and keep related scans together—for example, the front and back of a print. The Library of Congress recommends descriptive filenames, names and subject tags, and a brief description of a collection’s structure. The U.S. National Archives likewise emphasizes recording who, what, where and when.[4][13]
Then protect the files themselves. Keep copies in more than one place, check periodically that you can open them, and move them to current storage media when needed. The National Archives describes a useful 3-2-1 approach: three copies, on two types of media, with one copy off-site. No photo-sharing site or storytelling app should be the only place where your master scans live.[13][4]
A practical first session: Find one photograph whose story you can explain. Preserve its best available original; if it is a print, make a careful scan and capture any writing on the back. Create a viewing copy if needed. Finally, write three or four sentences about the people and the moment. That small, complete record is a better foundation than a large folder of unexplained scans.
H2: How MyHeirloom helps connect photos to a family legacy
Your TIFF masters and camera originals need a sound file-preservation plan. MyHeirloom addresses a related problem: helping the people who encounter a photograph understand why it matters.
In MyHeirloom, you can create a Keepsake around a memory, adding a supported photo such as a JPG or PNG alongside the story you want to tell. A photograph of a kitchen table, for instance, could become an account of the relative who cooked there, the people who gathered, and the recipe everyone remembers. If you date the Keepsake, it can also appear on your Life Timeline. Weaver can help you get started when you know a picture matters but are unsure how to describe it.
A Legacy Room brings those stories into a more meaningful structure than a scattering of phone albums, cloud folders and social posts. My Tribe and Family Tree can help preserve relationship context; the Family Cookbook offers a place for recipes and traditions connected to family photographs. This is how MyHeirloom helps turn scattered memories, relationships and important information into an organized, privacy-conscious legacy for future generations.
There is an important format distinction: do not assume a TIFF master can be uploaded as a Keepsake photo . MyHeirloom’s supplied product guidance identifies JPG and PNG as supported photo-upload formats. Keep your TIFF master in your own backed-up archive, then use an appropriate JPG or PNG copy to tell its story in MyHeirloom. The platform is a complement to good backup practices, not a reason to discard originals.
If you already have a photograph and a story in mind, start for free and make your first Keepsake about that one image. You do not need to digitize every album before beginning. For personal pictures, review visibility choices before sharing: MyHeirloom provides user-controlled privacy settings, so you can decide what you want to keep private and what you choose to make public.
H2: Conclusion
For newly scanned, significant family photographs, a TIFF master and a convenient JPEG copy are often a sensible pair. For existing camera photos, protect the best original file you have—even when it is a JPEG. Choose PNG when its lossless handling or crisp rendering serves a particular image. Above all, avoid converting files merely to give them a more “archival” extension: a new format cannot recover missing detail or supply a missing story.[37][49][40]
Preserving family photos is both a technical and a human task. Keep dependable copies of your files, but also record names, relationships and memories while someone can still explain them. Start for free with MyHeirloom when you are ready to give one photograph a place in a larger life story—and build from there, at a pace that works for you.
H2: FAQ
Question: Is TIFF always better than JPEG for archiving family photos?
Answer: No. TIFF is a strong choice for a new, high-quality master scan, but converting an existing JPEG to TIFF does not restore information already lost. If a camera-original JPEG is your best available version, keep it unchanged and backed up.[37][49]
Question: Should I scan every old photograph as a PNG?
Answer: You can use PNG for lossless image storage, but it is not a requirement for every print. For significant new scans, TIFF is a practical master format; PNG can be useful when crisp text or graphics are part of the image. Choose a workflow you can maintain, and check the actual scan quality rather than judging by its extension alone.[37][40]
Question: What should I do with writing on the back of a photograph?
Answer: Capture the back as well as the front, and use related filenames so the two images stay connected. Transcribe important names or dates in your notes, preserving uncertainty where the writing is unclear. Record who supplied any additional identification.[13]
Question: Can I upload my TIFF master directly to MyHeirloom?
Answer: The supplied MyHeirloom product guidance identifies JPG and PNG as supported photo formats, not TIFF. Keep a backed-up TIFF master outside the platform and use a suitable JPG or PNG copy in a Keepsake, where you can add the photograph’s story.
Question: If my photos are in MyHeirloom, do I still need backups?
Answer: Yes. Keep independent copies of your best original photos and scans. MyHeirloom helps organize and explain memories; it should complement, not replace, your file-backup routine. The U.S. National Archives recommends keeping copies across different media, including one off-site.[13]
