TIFF to JPG / PNG
Open a TIFF scan or a stack of them and export JPEG or PNG. Multi-page TIFFs export each page separately. Decoding runs in a Web Worker on this device.
No upload. Files never leave your device.

Frequently asked questions
Does this upload my scans?
No. Files are read in the browser and processed on your device. There is no conversion server.
What about multi-page TIFFs?
Each page is decoded and exported as its own JPEG or PNG (up to 24 pages per file). You can then download them one by one or as a ZIP.
Will quality be lost?
JPEG is lossy; use the quality slider. PNG keeps the pixels the decoder produces and is a better match for documents and line art. Very unusual TIFF compressions may fail; if that happens, try exporting the scan as a simpler TIFF first.
Can I convert many files at once?
Yes. Add multiple TIFF files, convert them, then download a ZIP.
Is there a file size limit?
Files larger than 40 MB are refused because they have to fit in your browser’s memory.
Which license covers the decoder?
Most browsers cannot read TIFF themselves, so this page uses UTIF.js (MIT), with pako (MIT and zlib) for compressed streams.
