How to convert JPG to TIFF
- Drop one or more
.jpgor.jpegfiles onto the drop zone above. - Click Convert to TIFF.
- Download each TIFF file, or use Download all to save them in a single ZIP archive.
The photos are decoded by your browser and written as TIFF with UTIF.js, locally on your device. Nothing is uploaded, and the converter is free with no account required.
Why convert JPG to TIFF?
Most of the time you would convert the other way, so why go from a small JPG to a large TIFF? Because some workflows simply require it. Print shops, publishers, photo labs, stock agencies, archive and records systems, and some document management or fax software accept only TIFF. Converting JPG to TIFF lets you hand them the format they ask for in a few seconds.
There is also a practical editing benefit. Every time a JPG is edited and saved again, it is recompressed and loses a little more detail. Converting to TIFF once gives you a lossless working copy that you can edit, save and reopen as often as you like without further degradation.
Why the TIFF is much larger
The converter writes uncompressed RGBA TIFF: four bytes (red, green, blue and alpha) for every pixel, with no compression at all. A 12-megapixel photo of 4000 × 3000 pixels therefore becomes roughly 48 MB, while the JPG may have been 3–5 MB. That is expected, not a bug.
- It is lossless. The TIFF stores exactly the pixels decoded from your JPG; nothing further is lost.
- It is the most compatible TIFF flavour. Uncompressed TIFF opens in practically every program that reads TIFF, including older RIP, prepress and archive software.
- It does not add detail. Converting cannot undo the compression the JPG already applied. For the best result, start from the highest-quality JPG you have.

| Typical use | Sharing, web, email | Print, publishing, archiving |
Frequently asked questions
Does converting JPG to TIFF improve quality?
No. The TIFF preserves the JPG exactly as it is, without further loss, but it cannot recover detail that JPG compression already removed.
Why is the TIFF file so big?
It is saved uncompressed with four bytes per pixel, so the size is roughly width × height × 4 bytes. That makes it lossless and widely compatible.
Can I convert many JPGs to TIFF at once?
Yes. Add as many photos as you need; each becomes its own TIFF file and all can be downloaded as a ZIP.
Are my photos uploaded?
No. The conversion happens entirely in your browser.
