TIFF files from scanners, print shops and archives routinely run to hundreds of megabytes, which is unusable for email, marketplace uploads or anything on the web. This free converter decodes the TIFF in your browser and writes a JPG at a quality level you choose, typically cutting the size by 95% or more with no visible difference on screen. Keep the TIFF as your archival master and treat the JPG as the copy you send. Nothing is uploaded.

How to use it
- Check the output is set to JPG — This page opens with the output format already set to JPG, so there is nothing to configure if that is what you came for. If you actually wanted something else, change it here — the same page converts to PNG, JPG, WebP, TIFF and PDF.
- Set the quality — JPG is lossy, so the slider runs from 40% to 100% and the resulting file size is shown after each change. Around 90% is the usual sweet spot — below about 80% you start to see haloing around text and hard edges.
- Add your TIFF files — Drag them onto the drop area or click to choose them — one file, or up to thirty at once. They are read in your browser, so nothing is uploaded, there is no queue and no account is needed.
- Let it convert — There is no Convert button — conversion starts as soon as a file is added, and the results panel shows the total size going in and coming out so you can see what the change cost or saved.
- Download the results — Each converted file has its own download link. If you converted several, "Download all as ZIP" saves the whole set in one action.
The problem this solves
A scanned TIFF is both too large to send and impossible to preview — the two problems arrive together. Uploading a 400MB file to a web converter is not a realistic answer either, which is why doing it locally matters here more than on any other pair.
What it does
Real TIFF decoding
No browser reads TIFF natively; this page carries a proper decoder, so the file is opened correctly instead of failing silently.
Quality you control
A slider from 40% to 100% with the resulting file size shown, so you can stop at the point where it is small enough and still looks right.
Full resolution kept
Only the compression changes — the pixel dimensions are untouched, so the JPG still prints at the same size the TIFF did.
Flattened predictably
JPG has no alpha channel, so any transparency in the TIFF is composited onto white rather than turning black.
Nothing is uploaded
The conversion runs in your browser using the same image pipeline the browser uses to show you a photo. Your file never reaches a server, there is no queue, and there is no account to make. It also means a large file is limited by your own machine's memory rather than by an upload cap.
Where it lives in PSDmate
Free and open on this page. Inside PSDmate, artwork of any size is handled server-side for mockup rendering and publishing.
Questions
How much smaller will the JPG be?
Usually 95–99% smaller. Most TIFFs are stored uncompressed, so almost all of that size is redundancy a JPG removes.
Should I delete the TIFF afterwards?
No. Keep it as the master. JPG compression is one-way, and if you later need to reprint or re-edit, you want the original.
My TIFF is enormous and the tab is struggling. What now?
Everything runs in your browser's memory, so a very large scan can exhaust it. Close other tabs, or convert it in a desktop application — that is a genuine limit of doing this locally, and the trade for not uploading your file.
Will this fix a TIFF that opens sideways?
Orientation is taken from the file, so a rotation stored as metadata carries over. If the pixels themselves are rotated, you will need to rotate them in an editor.
