Convert TIFF to JPG

Convert TIFF to JPG online, free and 100% in your browser. No upload, no signup, no size limit — WebAssembly does the work on your device.

How to convert an image

  1. Drop or pick your TIFF file — or paste it with Ctrl/⌘+V.
  2. JPG is already selected as the target; tune the quality slider if you like (default 82).
  3. Convert, compare the before/after, and download — all on your device.

Why convert to this format?

TIFF is a lossless format used in print and scanning workflows — high quality but far too large for the web. JPEG is the universal lossy photo format — small and readable everywhere, but with no transparency.

OptImg runs the same Rust codecs desktop tools use, compiled to WebAssembly, so you get desktop-grade JPG output at a sensible default (quality 82) — adjustable at any time — without ever uploading your image.

Everything happens locally: your TIFF is decoded, re-encoded to JPG and handed straight back as a download. No server sees a single byte, which is why there's no queue and no file-size cap.

Frequently asked questions

Is my TIFF uploaded to a server?
No. The TIFF-to-JPG conversion runs entirely in your browser with WebAssembly — your file never leaves your device, there is no queue, and no size limit beyond your device's memory.
What happens to transparency?
JPG has no alpha channel, so any transparent areas are flattened onto a white background. If you need to keep transparency, convert to PNG, WebP or AVIF instead.
Will converting TIFF to JPG lose quality?
JPG is lossy, tuned to a visually transparent default (quality 82) that you can raise or lower with the slider. If the conversion can't produce a smaller file than your original, we hand the original back instead.
Is the TIFF to JPG converter free?
Yes — completely free, with no signup, no watermark and no cap on how many files you convert. There is nothing to install; it runs in your browser.
