Compress an image to 100 KB

The roomiest of the common limits. A phone photo arrives forty times over it, but almost always fits at full resolution once the quality is tuned — no pixels lost, nothing uploaded.

Your photo never leaves this tab. The resizing happens inside your own browser — nothing is uploaded to us, and we cannot see the file.

Why your phone photo is forty times too big

Nothing is wrong with your camera. A phone writes a file meant to survive cropping, editing and printing — a form wants a picture that will be looked at once, in a box a few centimetres wide. Those are different jobs, and they need very different files.

What the 100 KB budget buys

• A head-and-shoulders portrait at full phone resolution, comfortably.
• A scanned certificate where the printed text stays readable.
• A photo of a document page, provided it was scanned straight and cropped.
• Almost anything you have already cropped to what actually matters.

Because the search starts from the highest quality and works down, the result at this limit is normally indistinguishable from your original on screen. Keep the original anyway — compression is not reversible, and this tool deliberately never touches the file you picked.

Tighter limit to meet? Try 50 KB or 20 KB, or set your own number on the main tool.

About the 100 KB limit

Why was my 4 MB photo rejected when the limit is only 100 KB?

Because a phone camera writes for a print, not for a form. A modern phone produces 3–6 MB per shot — forty to sixty times over this limit — and none of that extra detail is visible in the small box the reviewer sees it in. Compressing to 100 KB is discarding data you were never going to use.

Will I lose resolution at this limit?

Usually not. At 100 KB the quality search almost always reaches the target on its own, leaving your pixel dimensions untouched. The tool only scales down when quality alone cannot get there, and it tells you when it did.

Is a 100 KB JPEG good enough to print?

For a small photo on a form, yes. For anything printed larger than a few centimetres, no — and you should keep your original file for that. Compress a copy for the upload and leave the original alone; this tool never modifies the file you selected.
