TIFF to WebP Converter — Convert TIFF to WebP Online
Turn a print or archival TIFF into a web-ready WebP and drop 93–98% of the file size, or leave the quality slider at 100% for a WebP that is pixel-for-pixel lossless. Drop your TIFF below and pick WEBP as the output format. Free, private, and entirely in your browser with no upload required.

How Much Smaller Is WebP Than TIFF?
Enough that it changes what you can put on a page. An uncompressed TIFF spends three bytes on every pixel no matter what the picture contains; WebP predicts each pixel from its neighbours and stores only the difference. Converting the three photographs this site uses, each saved first as an uncompressed TIFF, gives:
| Test photo | Pixels | TIFF | WebP at 92% | WebP at 100% |
|---|---|---|---|---|
| dslr-camera.jpg | 1600 × 2000 | 9.2 MB | 245.5 KB −97.4% | 1.1 MB −87.5% |
| hero-memory-card.jpg | 1600 × 1067 | 4.9 MB | 115.4 KB −97.7% | 834.5 KB −83.3% |
| photo-grid.jpg | 1400 × 931 | 3.7 MB | 258.7 KB −93.2% | 1.2 MB −67.1% |
Both WebP columns come from this page's own converter, at the default 92% and at 100%. The 100% column is genuinely lossless — not “visually lossless” — and it still removes two thirds to seven eighths of the file. Note that photo-grid.jpg saves the least: it is a busy collage of many small photographs, and detail is exactly what compression cannot invent a shortcut for.
When WebP Replaces TIFF — and When It Must Not
These formats sit at opposite ends of an image's life. TIFF is where a photograph is stored and worked on; WebP is how it reaches a reader. Convert when the image is heading for a screen:
- Anything on a website: product shots, article images, galleries, thumbnails, hero images. WebP is supported by every current browser; TIFF is supported by almost none.
- Images with transparency: WebP keeps the alpha channel, so cut-outs and logos survive the trip, which is why WebP beats JPG here.
- Page-speed work: a 9 MB TIFF is not a slow image, it is a broken one. A 245 KB WebP is a fast one.
- Email and messaging: almost nothing outside a design studio opens a TIFF attachment.
Keep the TIFF, and do not ship the WebP, when the image is going anywhere professional software reads it: a commercial printer or prepress workflow, a library or museum deposit, a scientific or GIS pipeline, or back into Photoshop as an editing master. TIFF earns its size there by being simple, stable, and universally readable decades from now. The sound practice is to keep the TIFF as the master and generate a WebP whenever you publish — a conversion you can repeat, since the TIFF never degrades.
If WebP is not the target you want, the same TIFF converts to a universally readable TIFF to JPG copy, or to a lossless TIFF to PNG one. Choosing between the last two for a website is the whole subject of PNG vs WebP for your website, and if you are wondering whether to skip WebP for something newer, WebP vs AVIF weighs the trade.
How to Convert TIFF to WebP on Mac, Windows, and Linux
The converter above runs on all three and needs nothing installed: drop the TIFF in, choose WEBP from the Output Format menu, set the quality — 100% for lossless — and download. If you would rather use software you already have, here is the shortest route on each platform.
macOS
Preview opens TIFF but will not export WebP, so reach for the built-in sips command instead: sips -s format webp scan.tiff --out scan.webp. Add -s formatOptions 100 to raise the quality. WebP export arrived in sips with macOS 11 Big Sur; anything older will refuse the format.
Windows
Neither Paint nor Photos will save WebP, so use the converter above or install something that will. Windows 11 can at least open both formats out of the box; on Windows 10 you may need the free WebP Image Extensions package from the Microsoft Store before anything will display the result.
Linux
ImageMagick does it in a line — magick scan.tiff scan.webp on version 7, or convert scan.tiff scan.webp on version 6. Add -define webp:lossless=true for a lossless file, or -quality 92 to match this page's default. Google's own cwebp works too, though it wants a PNG or JPG rather than a TIFF as input.
Whichever route you take, keep the TIFF. WebP is the copy you publish; the TIFF is the copy you keep, and you can always convert it again — or convert it back with WebP to TIFF if the original is gone.
Frequently Asked Questions
Why convert TIFF to WebP?
Because a TIFF cannot go on a web page. Chrome and Firefox will not display one at all — a visitor gets a broken image icon — and even in Safari, which does render TIFF, you would be serving several megabytes where WebP serves a few hundred kilobytes. TIFF is a format for archives, print, and editing masters; WebP is a format for delivery. Converting the master you keep into the copy you publish is the normal end of a photo's journey, and it typically removes 93–98% of the bytes.
Does TIFF to WebP lose quality?
That depends entirely on where you leave the Quality slider. At 100% this converter writes a lossless WebP, and it is lossless in the strict sense: converting a 1600×2000 TIFF back and forth changed none of its 3,200,000 pixels. Below 100% you get a lossy WebP. At the default 92% the three test photographs on this page landed between 41.2 dB and 47.4 dB PSNR — a difference you will not see on a screen, at roughly a fifth of the lossless file size. So: lossless if you want it, and lossy only because you asked.
Best use cases for WebP over TIFF
Anything with a URL. Product photography, article images, portfolios, galleries, thumbnails, and hero images all belong in WebP: it is supported by every current browser, it carries transparency, and it is far smaller than TIFF at any quality you would ship. Keep the TIFF as the master you edit and archive from, and treat the WebP as the derivative you deploy. What WebP must not replace is the TIFF you send to a printer, deposit in a repository, or open in Photoshop as a working file — no prepress or archival workflow accepts it.
Will the WebP keep my TIFF's transparency?
Yes. WebP supports an alpha channel, so a TIFF with transparency converts to a WebP that keeps it, including partial transparency in soft edges and drop shadows. This is one of the places WebP beats JPG outright, and it is why converting to WebP rather than JPG is the right move for logos, product cut-outs, and anything that has to sit on a coloured background.
What happens to a multi-page TIFF?
You get the first page. A TIFF can hold a stack of images — scanned documents often do — but a WebP holds exactly one, so the converter takes page one and ignores the rest. If you need every page, split the TIFF into separate files first and convert them one at a time.
Can it read my TIFF? It came out of a scanner.
Almost certainly. No browser except Safari can decode TIFF on its own, so this converter carries its own TIFF decoder, and it handles what scanners and cameras actually produce: uncompressed, LZW, PackBits and Deflate images, CCITT Group 3 and Group 4 fax compression, tiled and stripped layouts, 16-bit samples, grayscale, palette, bilevel, CMYK, and both byte orders. The one variant it turns away is a JPEG-compressed TIFF whose scan is stored as RGB, because it cannot be decoded correctly here — rather than hand back an image with mangled colours, the converter says so and asks you to re-save as an uncompressed or LZW TIFF.
My TIFF is CMYK. What happens to the colour?
It is converted to sRGB, because WebP has no CMYK mode — no web image format does. That is the right conversion for a picture headed to a screen. It is also a one-way trip: do not convert a CMYK TIFF to WebP and then send the WebP to a printer. Keep the CMYK original for print and let the WebP serve the web.
Is there a size limit?
The WebP format caps each side at 16,383 pixels, and browsers enforce this by silently cropping rather than refusing. A 16,384-pixel-wide TIFF converts to a WebP exactly 16,383 pixels wide, one column short, with no warning. Large flatbed and film scans reach this range, so check the dimensions of the result if your source is enormous — and downscale it deliberately, in an editor, rather than letting the encoder take the decision for you.
Are my files uploaded to a server?
No. The TIFF is decoded in JavaScript on your machine and the WebP is encoded by your own browser. Nothing is uploaded, there is no sign-up, no watermark, and no file limit — which also means confidential scans, client artwork, and unpublished photography never leave your computer.
