TIFF to JPG Converter
Convert TIFF scans and multi-page faxes to JPG or PNG in your browser: pick pages, quality and background. LZW, Deflate, CCITT, CMYK. No upload.
TIFF is the format of scanners, fax software, print shops and archives: it can hold several pages in one file, store lossless or uncompressed pixels and use CMYK colour. Chrome, Edge and Firefox cannot display it, and most websites will not accept it. This converter turns each TIFF page into a JPG (or PNG) you can view, email or upload — the decoding happens in your browser, so files never leave your device.
How to use this tool
- Drop one or more .tif or .tiff files.
- Choose JPG (smaller) or PNG (lossless) and the JPG quality.
- Pick the first page, all pages (they download as a ZIP), or a list such as 1-3, 5.
- Download the images.
Formula
Pages are counted by reading the TIFF header (II or MM, 42) and following each image directory's "next IFD" offset. Each page is then decoded by the fastest method that can read it and encoded with the browser's JPEG or PNG encoder.
Safari decodes TIFF itself. Elsewhere a small built-in reader handles uncompressed, PackBits, LZW and Deflate files with 1, 4, 8 or 16 bits per sample (greyscale, RGB, palette and CMYK). Anything else — CCITT Group 3/4 fax, JPEG-in-TIFF, tiled files — goes to the full ffmpeg decoder, a one-time download of about 30 MB in Chrome and Firefox.
Example
A three-page fax saved as scan.tiff with "All pages" gives scan-p1.jpg, scan-p2.jpg and scan-p3.jpg, plus a "Download all as ZIP" button. With "Choose pages" set to 2-, only pages 2 and 3 are converted.
Frequently asked questions
Why does the first conversion take longer?
Some TIFF compressions (fax CCITT, JPEG-in-TIFF) need the full decoder engine, about 30 MB, which the browser downloads once and then reuses. Common LZW and uncompressed scans do not need it.
Do I lose quality?
JPG is lossy: 90% looks the same as the original for scans and photos at a fraction of the size. Choose PNG if you need an exact, lossless copy.
Why do CMYK colours look a little different?
Print files use CMYK ink values. They are converted to screen RGB with a standard formula; without the file's colour profile, some colours may shift slightly.
