Convert TIFF to WebP
To convert TIFF to WebP, add your .tiff file below and press the button: it's processed on your own device and you download the result, with nothing uploaded. It's free, needs no account, and works with files up to 500MB.
About converting TIFF to WebP
TIFF (.tiff) files can be converted to WebP entirely in your browser — no software to install, no file upload, and no account required. The conversion runs on a WebAssembly build of ffmpeg directly on your device.
Technical comparison
| TIFF | WebP | |
|---|---|---|
| Category | image | image |
| Compression type | Lossless (or uncompressed) | Lossy or lossless (configurable) |
| Typical file size | Large — high bit depth and often lossless compression | Small — often 25–35% smaller than an equivalent JPEG |
| Transparency support | Yes | Yes (full alpha channel) |
How to convert TIFF to WebP privately
Every step below runs on a WebAssembly build of ffmpeg inside this browser tab. Your .tiff file is never uploaded to a server — there's no network request carrying it anywhere.
Add your TIFF file
Drag and drop, or click to select, a file (.tiff). It's read straight from disk into browser memory — no upload step exists.
Convert locally
FreePrivateConvert converts it to WebP using a WebAssembly build of ffmpeg, entirely within this browser tab.
Download the result
Save your converted .webp file. It only ever existed in this tab's memory — closing the tab without downloading discards it completely.
Convert TIFF to WebP with ffmpeg (command line)
Prefer the terminal? This is the exact ffmpeg command this page runs for you:
ffmpeg -i input.tiff -c:v libwebp output.webp- -i input.tiff
- Your TIFF file.
- -c:v libwebp
- Encode the image as WebP.
- output.webp
- The WebP file to create. ffmpeg picks the container from this extension.
Don't have ffmpeg installed? You don't need it: use the converter at the top of this page. It runs the same conversion on your own device, and your file is never uploaded.
FAQ
- Is my file uploaded anywhere?
- No. Your file is read and processed inside this browser tab and never leaves your device. You can confirm it in your browser's developer tools: the Network tab shows no upload.
- Does converting TIFF to WebP reduce quality?
- WebP here is lossy at libwebp's default quality (75), which keeps photos looking good at a much smaller size.
- Is there a file size limit?
- Yes: 500MB per file. There's no account and no limit on how many files you convert.
- What's the difference between TIFF and WebP?
- TIFF (Tagged Image File Format) and WebP store data differently. TIFF: lossless (or uncompressed). WebP: lossy or lossless (configurable). WebP is Google's modern image format, supporting both lossy and lossless compression plus alpha transparency and animation in one file type.
- Why convert TIFF to WebP?
- Common uses for WebP: Web page hero and background images; Responsive <picture>/srcset fallbacks; Replacing animated GIFs to cut page weight. Lossy WebP typically produces 25–35% smaller files than JPEG at equivalent visual quality.
- What MIME type does a .webp file use?
- image/webp, the standard type for WebP.
- What is the ffmpeg command to convert TIFF to WebP?
- Run: ffmpeg -i input.tiff -c:v libwebp output.webp. This is the exact command FreePrivateConvert runs for this conversion, so you can use this page instead of installing ffmpeg: it runs the same conversion inside your browser.
