No TIFF to hand?
JPG puts a faint halo around text and mottles flat backgrounds, which on a scanned page you will notice. PNG keeps every pixel exactly and opens in everything too.
Convert to PNG insteadHow to convert a TIFF to JPG
Both spellings, .tiff and .tif, and as many as you like. They are read off your disk into this tab and never sent anywhere.
If something gave you a limit, turn on the target box and put the figure in. We search for the highest quality that fits under it rather than making you guess.
Drag the divider and find the smallest writing on the page. That is where JPG shows its working, and where a bigger width or a target you set too low will show first.
Why the scan is so big, and how much the JPG saves
A TIFF usually stores its pixels raw, or under a mild lossless coding such as PackBits. An A4 page scanned at 600 dpi is about 5000 by 7000 pixels, and at three bytes each that is a hundred megabytes before anything has been compressed. Nothing about the picture requires that. It is the format doing exactly what archivists ask of it: keep every sample, take as long as you like, use as much disk as you need.
JPG makes the opposite trade. It discards the fine colour detail your eye is worst at noticing and codes the rest tightly, which on a photograph or a colour scan is a saving of ninety per cent and upwards with nothing visible at normal viewing size. On a scan that has already been compressed with LZW or Deflate the starting point is lower, so the drop is smaller, but it is still large.
The cost lands on hard edges. Black text on white is the worst case for JPG: letters pick up a faint grey halo and flat backgrounds develop a gentle mottling, both of which are more obvious at 100% than they are on paper. If the scan is a document you will read rather than a photograph you will look at, convert it to PNG instead and keep every pixel.
TIFF to JPG FAQ
How much smaller will the JPG be?
From an uncompressed or PackBits TIFF, which is what most scanners write, expect somewhere between ninety and ninety-eight per cent off. From a TIFF that was already LZW or Deflate compressed the file was doing better to begin with, so the drop is nearer seventy to ninety. Either way the result panel shows you the real figure for your file rather than a promise.
What happens to a multipage TIFF?
The first page is converted and the rest are left where they are, in the TIFF you still have. A scanner or a fax gateway writes every sheet into one TIFF quite happily; a JPG holds exactly one image and has nowhere to put the others. The result panel says how many pages it found, so you can see straight away whether you have the whole document. To convert them all, split the TIFF into single pages in a viewer first, then drop the lot here at once.
Why is there no quality slider?
Because the size box is a better answer to the question people are actually asking. Quality is fixed at 78, which is a sensible setting for a scan, and if you need a specific figure then "Compress to a target size" searches the quality for you and tells you where it landed. A slider gets you there by trial and error; the box gets you there once.
Which TIFFs can this page read?
Uncompressed, PackBits, LZW and Adobe Deflate, at 8 bits per sample, in RGB, greyscale or palette. That covers what scanners, ImageMagick and ffmpeg write. A 16-bit archival scan, a CMYK file from a print workflow, a tiled TIFF or a JPEG-in-TIFF is refused by name rather than decoded into something that looks wrong: re-export it as an 8-bit RGB TIFF and it will convert.
My TIFF has a transparent background. What happens to it?
It is filled with white, permanently. JPG has no alpha channel at all, so transparency has to be flattened onto something and white is what a scan or a print export was sitting on anyway. If the transparency matters, convert to PNG instead, which keeps it exactly.
Can I turn the JPG back into a TIFF later?
You can, and it will not undo anything. What JPG discarded on the way out is gone, and a TIFF written from the JPG is a lossless copy of the damaged picture at many times the size. Keep the original TIFF if it is the archive copy, and treat the JPG as the one you send.
Are my TIFF files uploaded to convert them?
No. The TIFF is decoded and the JPG is written by your own browser, in this tab. There is no upload endpoint in the site for a file to go to, which you can check in your network tools: convert something and watch that no request carries it. Disconnect from the network after the page loads and it still works.
Does this remove EXIF, GPS and AI metadata?
Yes, every time, and there is no way to turn it off. The image is decoded to pixels and encoded again from those pixels alone, so EXIF and GPS, the XMP packet, embedded colour profiles, and any Content Credentials or AI-generation tags the file arrived with do not survive. There is no switch for this, because there is no way to keep them. What no compressor can remove is a watermark written into the pixels themselves, such as the invisible marks some image generators add: those survive re-encoding here and everywhere else.
