How it works

Three steps. No upload, no signup.

  1. 1

    Drop your file

    Click the dropzone above or drag a TIFF from your desktop. Files of any size, there's no upload, so there's no upload limit.

  2. 2

    Convert in your browser

    The conversion runs entirely in this tab using JavaScript and WebAssembly. Your file never touches our servers, we don't have any.

  3. 3

    Download

    Get your WebP the moment the conversion finishes. Convert another, or close the tab.

Files stay on your device

Your file is never uploaded. The entire conversion runs in your browser using WebAssembly. We can't see what you convert because we have no server to see it.

No file size limit

Server converters cap free users at 1-2 GB and gate larger files behind a paid plan. Since nothing uploads, our limit is whatever your browser can handle.

Free, no signup, no ads on conversions

No account required. No watermark on the output. No queue. Drop a file, get a converted file.

Why convert TIFF → WebP

What this conversion is actually for

WebP is 25 to 35 percent smaller than PNG or JPEG at equal quality and is supported across all modern browsers. This decodes the TIFF and re-encodes TIFF images to WebP entirely in your browser, so the file never leaves your device. Source transparency is preserved.

A real example

You have a TIFF image and need WebP for a site, app, or workflow that requires it. Drop the TIFF here and download the WebP, no upload.

Troubleshooting

Multi-page TIFF only converted the first page.

This reads the first image in the TIFF. For multi-page TIFFs, split the pages first or use a multi-page-aware tool.

About TIFF and WebP

TIFF, Tagged Image File Format

TIFF is the workhorse format for professional imaging, scanning, prepress, archival photography. It supports lossless compression, multiple pages per file, layered data, and 16-bit-per-channel color depth (vs 8-bit in JPG/PNG). Files are large; the tradeoff is fidelity. Most consumer software doesn't display TIFF in browsers, which is why archivists frequently convert to JPG or PDF for sharing.

How to open

macOS Preview, Windows Photos, and most professional image editors (Photoshop, Capture One, Lightroom) read TIFF. Browsers generally do not display it inline; you'll need a viewer or to convert.

WebP, Web Picture

WebP is Google's image format, designed in 2010 specifically for the web. It compresses 25-35% smaller than JPG at equivalent quality, supports transparency like PNG, and supports animation like GIF. Browser support is universal as of 2020 (Safari was the last holdout). The main reason most images aren't already WebP: legacy software (older Office versions, some email clients) doesn't open it.

How to open

All modern browsers display WebP natively. Photoshop added native support in version 23 (2021); earlier versions need a plugin. macOS Preview reads WebP since macOS Monterey. On Windows, the Photos app supports it; older viewers may not.

FAQ

Common questions

Is this TIFF → WebP converter really free?

Yes. No signup, no watermark, no daily file count limit. Every conversion runs in your browser, your file never touches our servers because there are no servers.

Where does my file go when I convert it?

Nowhere. The conversion runs entirely in your browser using JavaScript and WebAssembly. Your file is never uploaded to our servers. We don't have any servers handling files, there's nothing for us to log, store, or accidentally leak.

What's the maximum file size?

Whatever your browser can hold in memory. Practically, this means a few hundred MB on most computers, significantly larger than the 1-2 GB caps that server-upload converters charge for. Very large files (multi-GB) may require closing other browser tabs first.

Why convert TIFF to WebP?

Scanning, prepress, archival imagery, multi-page documents. Modern web imagery where smaller files load faster. The most common reason to convert is compatibility, WebP works in places where TIFF doesn't, or vice versa.

How do I open a TIFF file in the first place?

macOS Preview, Windows Photos, and most professional image editors (Photoshop, Capture One, Lightroom) read TIFF. Browsers generally do not display it inline; you'll need a viewer or to convert.

Does this work offline?

Once the page is loaded, the conversion itself runs entirely offline. The first time you use a tool, your browser downloads the conversion library (a one-time cache). If you reload while offline, the page won't load, but you can install the site as a Progressive Web App for full offline use.

Can I convert multiple files at once?

Single file at a time for now. Batch conversion is on the roadmap, for now, drop one file, download the result, then convert the next.
