GIF to TIFF converter
Drop one or more GIF files and download them as TIFF. The conversion runs entirely in your browser: no upload, no queue, no account, no watermark.
This direction uses the full conversion engine: your first file downloads it (~14 MB) and takes a little longer. Everything still happens in your browser.

or pick them from your device: several at once is fine
Files never leave your device: this page has no server to send them to.
How it works
For this direction the page loads a full image engine (ImageMagick compiled to WebAssembly) the first time you pick a file, then decodes GIF and re-encodes it as TIFF on your device. Nothing is uploaded; the engine download happens once per visit.
Frequently asked questions
Is this converter really free and private?
Yes. The conversion happens inside your browser using its built-in image engine. Nothing is uploaded, so there is nothing for a server to keep, and there is no account, limit or watermark.
What happens to transparency?
PNG and WebP keep transparent backgrounds. JPG has no transparency, so transparent areas are flattened onto white during conversion.
Why convert GIF to TIFF?
TIFF is often the format a form, tool or platform actually accepts. Converting locally gets you a compatible file in seconds without trusting a third-party uploader.
