TIFF to JPG Converter
Decoded in your browser. No browser can display TIFF natively, so a decoder is loaded on demand.
The TIFF to JPG converter decodes TIFF files and exports them as JPEG. No browser can display TIFF natively, so a decoder is loaded when you open this page, which is also why every other online TIFF converter uploads your file to a server. This one does not.
How it works
TIFF is a container format rather than a single encoding. A TIFF file can hold uncompressed data, LZW, PackBits, JPEG or several flavours of CCITT fax compression, in any of a dozen colour arrangements. That flexibility is why browsers never implemented it.
- The file is parsed into its image directories. A TIFF can contain many pages.
- The first page is decoded to raw RGBA and drawn to a canvas.
- The canvas is exported as JPEG at the quality you choose.
- Multi-page files are reported, since scanners routinely produce them and people expect one image.
JPEG has no alpha channel, so any transparency in the source is composited during the canvas draw. TIFF files with an alpha channel are uncommon but do exist.
Examples
A single-page scan
File
A 2,480 × 3,508 TIFF at 4.2 MB
Quality
90%
Result
A JPEG of the same dimensions, typically under 800 KB
A4 at 300 DPI is 2,480 × 3,508 pixels. Uncompressed TIFF stores this at roughly 26 MB; LZW compression is what brings it down to 4 MB.
A multi-page fax
File
A 6-page TIFF
Result
Page 1 is decoded, and the tool reports that 6 pages were found
Multi-page TIFF is standard for scanners and fax software. Only the first page is converted, which the status line makes explicit rather than leaving you to wonder.
Frequently asked questions
Why can browsers not open TIFF files?
Because TIFF is a container that permits many different compression schemes and colour arrangements, several of them patent-encumbered historically. Supporting it properly means implementing a dozen decoders, and browser vendors decided the format was not common enough on the web to justify it.
Is my file uploaded?
No. The decoder runs in your browser and the file is read locally. Most online TIFF converters do upload, because doing it client-side requires shipping a decoder, which this page loads on demand, about 40 KB.
Why does only the first page convert?
Because a multi-page TIFF is really several images in one file, and most people converting one want a single image. The tool reports how many pages it found so you know whether anything was left behind.
My scan is text, not a photo, is JPEG the wrong choice?
Usually yes. JPEG artefacts are worst exactly where scanned text lives: sharp black-on-white edges, where it produces visible ringing around every letter. For scanned documents and line art, run the TIFF through here and then convert the result to PNG or WebP with the image converter.
