Convert TIFF to PNG
TIFF scans are huge and won’t open on the web or most phones. Convert them to lossless PNG here — without uploading sensitive documents anywhere.
TIFF vs PNG: what changes
TIFF is the format scanners, fax tools, and print shops produce. It’s lossless and high quality, but the files are enormous and barely supported outside professional software — try opening a .tif on a phone or in a browser and it usually fails.
Converting to PNG keeps the lossless quality while making the image open literally everywhere, with full transparency support. Since scans often contain documents, IDs, or contracts, doing the conversion locally matters: with FavGrab the file never leaves your browser, so nothing sensitive is uploaded to a stranger’s server. The TIFF decoder loads automatically the first time you add one.

Why convert in your browser
Nothing is uploaded
Every byte is decoded and re-encoded on your own machine using Canvas and WebAssembly. Your images never touch a server, so there is no upload bar, no queue, and no copy of your file sitting in someone else’s bucket.
Works offline
After the first load the converter is cached. Open it on a plane, on hotel Wi-Fi, or with the cable unplugged and it still runs at your CPU’s full speed.
Frequently asked questions
Is TIFF to PNG lossless?
Yes — TIFF is typically lossless and the PNG step is lossless too, so every pixel is preserved. PNG just makes the image far more portable than TIFF.
Are my scanned documents uploaded?
No. The whole conversion runs in your browser with WebAssembly, so private scans, IDs, and contracts never leave your device.
What about a multi-page TIFF?
The converter renders the first page of the TIFF as a single PNG. For multi-page documents, convert each page you need separately.
Can I convert a batch of TIFFs at once?
Yes — add as many as you like, convert them together, and download a single ZIP of all the PNGs.
