TIFF vs PNG: which lossless format should you use?
By Andrew Butson · July 2, 2026 · 7 min read
Use PNG for anything that ends up on a screen, such as websites, apps, screenshots and icons, and TIFF for anything that ends up in a scanner, a printer, or a professional editing pipeline. Both are lossless, so neither one degrades your image; the difference is which world each format was built to serve.
TIFF and PNG are often lumped together because both promise not to throw away any pixels. That much is true of both, and it is also close to where the similarity ends. TIFF grew up in scanning bureaus, print shops and photo archives, where a file might need to hold sixteen bits per channel, several pages, or a stack of editable layers. PNG grew up on the web, where the job is simpler: reproduce a screenshot, logo or icon exactly, keep transparency intact, and stay small enough to load fast.
Picking between them is really a question of where the file is going next, not which one is "better" in the abstract.
| TIFF | PNG | |
|---|---|---|
| Compression | Lossless, or none at all | Lossless (DEFLATE) |
| Typical file size | Large, often tens of megabytes | Small to moderate |
| Multi-page support | Yes — one file, many pages | No — one image per file |
| Layers | Yes, in many TIFF variants | No |
| Colour depth | Up to 16 bits per channel | 8 or 16 bits per channel |
| Transparency | Yes | Yes |
| Browser support | None — browsers cannot display TIFF | Universal |
| Typical use | Scanning, printing, archiving, pre-press | Web graphics, screenshots, icons |
Two lossless formats, two different jobs
Calling both formats "lossless" makes them sound interchangeable, but lossless only means the file keeps every pixel value it was given. It says nothing about what else the format can carry, or where it can be opened. TIFF is closer to a container than a single image format: depending on how it is saved, a TIFF can hold multiple pages, embedded colour profiles, layered edits carried over from an editing app, and colour depth well beyond what a typical screen can show. That flexibility is exactly what a print shop, a document scanner or an archive needs, because those workflows care about preserving everything a professional process might later need.
PNG was designed for a narrower, more specific job: put an exact copy of an image on a web page. It has no concept of pages or layers, and in practice it tops out at the colour depths a screen actually uses. What it does have is universal support: every browser, phone, operating system and image tool opens a PNG without a second thought, which is not true of TIFF at all.
Where TIFF is the right answer
Scanning bureaus and print shops ask for TIFF for a reason: it is the hand-off format between a scanner and publishing software, and it is what most professional pre-press tools expect. A document scanned at high resolution for archival purposes, a photograph destined for offset printing, or a multi-page fax captured as one file are all classic TIFF territory. Photographers who shoot RAW and want a fully-edited, layered master file, rather than a flattened export, will often save that master as TIFF too, since it can preserve layers the way a working file needs to.
None of this matters if the image is only ever going to be viewed on a screen. TIFF files are large, often tens of megabytes for a single high-resolution scan, and no web browser will display one at all. Emailing a TIFF to someone expecting to just look at it in their browser is a reliable way to produce a confused reply.
Where PNG is strictly better
Anything destined for a screen belongs in PNG rather than TIFF, full stop. A screenshot, a logo with a transparent background, an icon, a diagram with sharp text and flat colour: these are precisely the images PNG compresses well and every piece of software can open. The file will be a fraction of the size of an equivalent TIFF, it will display instantly in a browser, and it will paste cleanly into a chat app, an email, or a slide deck without anyone needing special software.
PNG also wins whenever universal compatibility matters more than archival flexibility. If you are not sure what will open the file next, PNG is the safer bet, because there is essentially nothing modern that fails to read it.
Going from one to the other
The common direction is TIFF to PNG: a scanned document or a TIFF export from an editing tool needs to go on a website or into an email, and PNG is the format everything downstream actually understands. Converting keeps the image lossless, since nothing is thrown away in the process, but it does flatten anything TIFF-specific that PNG cannot represent, such as multiple pages (only one page carries across) or embedded layers (the image comes across as it currently looks, already flattened).
Going the other way, from PNG to TIFF, is far less common and mostly shows up when a print workflow specifically demands a TIFF wrapper around what is otherwise an ordinary web image. Wrapping a PNG in TIFF does not add back detail the PNG never had. It just repackages the same pixels into a format the print pipeline will accept.
Reach for TIFF when…
- A print shop, publisher or pre-press tool specifically asks for it.
- You are scanning documents or photos for long-term archival storage.
- The file needs to hold multiple pages in one document.
- You are keeping a layered master file from an editing app rather than a flattened export.
- Colour depth beyond 8 bits per channel actually matters to the job.
Reach for PNG when…
- The image is going on a website, in an app, or into a screenshot.
- You need a transparent background that any browser will render correctly.
- File size and fast loading matter.
- The recipient needs to open it without installing anything extra.
- You are not sure what will open the file next, and want the safest, most universal option.
Turn a scanned or exported TIFF into a PNG that opens anywhere, right in your browser — nothing is uploaded.
Runs entirely in your browser — nothing is uploaded.
Frequently asked questions
- Is TIFF higher quality than PNG?
- Not inherently. Both can be fully lossless, keeping every pixel exactly. TIFF can go further in colour depth and can carry multiple pages or layers, which is why professional print and scanning workflows prefer it, but a standard 8-bit PNG loses nothing compared with an 8-bit TIFF of the same image.
- Why won't my browser open a TIFF file?
- Browsers were never built to decode TIFF. It was designed for print and archival pipelines, not the web, so no mainstream browser added native support. Converting the TIFF to PNG (or JPEG) makes it viewable anywhere.
- Does converting TIFF to PNG lose quality?
- No — both are lossless formats, so the pixels themselves come across unchanged. What can be lost is anything PNG has no way to represent, such as extra pages beyond the first or layers that get flattened into the final look of the image.
- Can PNG replace TIFF for scanning?
- For everyday document scans that just need to be shared or filed, PNG is fine and far more convenient. For archival scanning, multi-page documents, or anything heading to a print shop, TIFF remains the expected format.
