Why is the file bigger than the JPG?

JPG is compressed. This TIFF is uncompressed RGBA, so it's much larger. In return you get no further quality loss and broad print compatibility.

Does converting back to TIFF improve quality?

No. The JPG already threw away some detail. TIFF just stops the bleeding. It can't recover what's gone.

JPG to TIFF

Re-encodes JPG pixels into lossless TIFF, with no further quality loss.

What this does

This decodes each JPG and writes the pixels out as an uncompressed RGBA TIFF. The TIFF is lossless, so it adds no further quality loss on top of the JPG, in exchange for a much larger file and broad print compatibility.

How it works

1Drop your JPG images.
2Each one gets re-encoded as an uncompressed TIFF.
3Download them one by one, or grab the whole batch as a zip.
