About Convert to TIFF
About TIFF
TIFF is the professional archive and print format. It can hold multiple pages, high bit depths and lossless data, and is common in scanning, publishing and GIS.
A TIFF begins with 'II' or 'MM' for the byte order and the number 42, then an offset to the first image file directory (IFD): a table of tags giving the size, compression, colour model and the location of the strips or tiles of pixels. Each further page is another IFD.
Strengths: Lossless and print-ready; Multiple pages in one file; Preferred by print shops and archives.
Drawbacks: Very large files; Browsers cannot display it; Many variants and compression schemes.

Frequently asked questions
Which apps open TIFF files?
Photoshop, Lightroom, GIMP, Affinity, macOS Preview, Windows Photos and print RIPs. It opens in Safari only; other browsers do not display TIFF.
Which formats can I convert from?
Anything this site can read: JPG, PNG, WebP, AVIF, HEIC, GIF, SVG, TIFF, BMP, ICO, JPEG XL, PSD, RAW and more. Files are identified by their bytes, so a mislabelled file still converts.
Are my images uploaded anywhere?
No. Processing happens inside your browser with WebAssembly and Web Workers. The site only downloads the app code and codecs; your files never leave your device. You can confirm this with the live upload counter on the tool, or in your browser's network panel.
Can I process many files at once?
Yes. Drop a whole selection or folder. Files are processed in parallel on several worker threads, each result can be downloaded on its own, and everything can be saved as one ZIP.
Is it free? Is there a file limit or watermark?
It is free with no account, no watermark and no daily limit. The only limit is your device's memory: very large images (over roughly 100 megapixels) may be refused to keep the tab from crashing.
