JPG to TIFF Converter
A print shop, archive or editing workflow has asked you for a TIFF, and all you have is a JPG. This converter writes an uncompressed TIFF from your photo on your own device. Read what the file will and will not contain first, because the change is about format, not about getting back quality.

How to convert JPG to TIFF
- Add your JPG files by dropping them, clicking the drop zone or pasting.
- The output format is already set to TIFF. Adjust quality or size if you need to.
- Press Convert and compare the original and new size for each file.
- Download each file or all of them as a ZIP.
When to convert, and when not to
- A printer, publisher or archive lists TIFF as the only accepted file type.
- A program in your workflow imports TIFF cleanly but handles JPG badly.
- You want a copy that no further save can degrade, before you start retouching.
- Do not convert for web use or e-mail: the file becomes much larger and gains no visible quality.
What changes
- The pixels are written without any compression, so the TIFF is far bigger than the JPG it came from.
- The picture is stored as 8-bit colour with an alpha channel, which is fully opaque because a JPG has no transparency.
- Camera details, location and colour profile are not copied into the new file.
- Phone photos are turned the right way up using their rotation tag before saving.
- There is no quality slider and no compression choice, because this TIFF is always uncompressed.
What you get from a TIFF made out of a JPG
A TIFF is a container that can hold pixels in many ways. This tool always writes the plainest one: a single image, eight bits per colour, with the pixels stored exactly as they are decoded. Nothing is thrown away by the conversion itself, so the TIFF shows precisely what your JPG showed.
The catch is that the JPG already lost detail when it was first saved. Writing it into a TIFF does not bring that detail back, and blocky or smeared areas remain visible. What the TIFF gives you is stability: you can open and save it again without the JPG's compression stacking up another round of damage.
Why the file gets so large
A JPG is small because it compresses aggressively. An uncompressed TIFF stores every pixel in full, so its size is set by the pixel dimensions, not by how simple the picture is. A plain blue sky and a busy street produce TIFFs of about the same weight at the same size.
If a print shop gives a size limit for uploads, check it before converting a whole batch. The Resize option can reduce the pixel count by percentage or to a maximum width and height, and that is the only way to shrink this file, because TIFF output here has no compression setting.
Preparing a photo for print
Printers usually care about pixel dimensions more than the file type. Look at the size your print job needs and confirm the JPG is not smaller than that before converting. Enlarging a picture while converting adds pixels but no detail, so it will not rescue a photo that is too small for the print.
Because metadata is dropped, any colour profile embedded in the JPG is not written to the TIFF. If your workflow depends on a specific profile, convert in a tool that preserves it, or assign the profile again in your editor.
Privacy: your files stay on your device
- The tool decodes, resizes and encodes your pictures with your browser. The files are never sent to a server.
- To check it yourself: open the browser developer tools (F12), open the Network tab, convert a file, and look for any request that carries your image. You will see none.
Frequently asked questions
Will the TIFF look better than my JPG?
No. It shows the same picture. The TIFF simply stops the file from being compressed again when you save it later.
Why is my TIFF so much bigger than the JPG?
This TIFF stores every pixel without compression. Compare the two sizes shown next to your file, and use Resize if you need it smaller.
Can I choose LZW or ZIP compression?
No. The converter writes one plain, uncompressed kind of TIFF so that almost any program can open it.
Is the colour profile kept?
No. Metadata, including the profile and camera details, is not written to the TIFF.
Does it make a multi-page TIFF from several JPGs?
No. Each JPG becomes its own single-image TIFF, and you can download them all as a ZIP.
