Convert TIFF to PNG in your browser: drop a .tif or .tiff file and every page comes back as a lossless PNG that any browser, document editor or upload form will open. TIFF is what scanners, fax software and print workflows tend to produce, and it is often large and awkward to share. PNG stores the same pixels without compression loss and keeps transparency where the TIFF has it, which makes it the right target for scanned documents, line art and anything with sharp text. The file is decoded on your device, so a scanned contract or ID never leaves it.
How it works
- Drop one or more TIFF files, .tif or .tiff. Preview shows page one of a multi-page file and how many pages it holds.
- PNG is already selected. There is no quality to set, because PNG is lossless.
- Press Convert & download. A single page saves as one PNG; a multi-page TIFF saves as name-p1.png, name-p2.png and so on, together in one ZIP.
Questions
- Can I convert a multi-page TIFF to PNG?
- Yes. Every page is decoded and saved as its own PNG, numbered -p1, -p2 and onward, and the set downloads as one ZIP with a report of what was converted. If one page of a long scan is damaged, that page is skipped and the others still convert, instead of the whole file failing.
- Is converting TIFF to PNG lossless?
- For ordinary 8-bit TIFFs, yes: PNG stores every decoded pixel exactly, transparency included. Two things do not survive. A 16-bit-per-channel TIFF is reduced to 8 bits per channel, which rarely shows on screen but matters for heavy editing. And metadata is not carried over, including the DPI value a scanner records, so set the print size again if you need it.
- Why is the PNG smaller than my TIFF?
- Many TIFFs are saved uncompressed, while PNG compresses losslessly, so the same pixels take less space without changing any of them. A TIFF that was already compressed, or a photo full of fine grain, can come out about the same size or larger. The result line shows the exact size of each PNG.
- Does my file get uploaded?
- No. The models and all processing run inside your browser on your own device. You can verify this yourself: open your browser’s DevTools, watch the Network tab, and process a file: there are no uploads. After the first visit most tools also work fully offline.
- How are RAW files converted?
- Honestly: RAW files carry a full-size JPEG preview rendered by the camera, and that is what this tool extracts, instantly and losslessly. It does not demosaic the sensor data; a RAW developer with your own processing choices is the right tool for that.
- Why does HEIC need a special decoder?
- Browsers do not decode HEIC, so this page ships an open-source decoder (libheif, compiled to WebAssembly) that runs on your device. The photo itself still never leaves your machine.
