Compress image to 10 KB
Set the budget, and the encoder is searched for the best quality that fits under 10 KB. On your device — the image is never uploaded.

Where a 10 KB limit comes from
Nobody chooses 10 KB for fun. If you are here, a form told you to, and the form probably did not explain how. These are the places this particular number turns up:
- Signature and thumbnail fields on older government portals
- Avatar uploads on legacy forums and intranets
- Inline images in strict email newsletter templates
Ten kilobytes is genuinely tiny — about one 60×60 pixel icon at reasonable quality. A full portrait squeezed to 10 KB will be soft and blocky no matter which tool does it.
What 10 KB actually buys you
Ten kilobytes is below the point where the format argument matters more than the settings. A JPEG spends bytes on an 8×8 block grid before it stores a single detail, so at this budget a large fraction of the file is structure rather than picture. PNG is worse still for photographs and better for anything flat.
The practical move at 10 KB is to stop thinking of it as compression and start thinking of it as choosing dimensions. Decide how many pixels 10 KB can carry — roughly 60×60 at decent quality, perhaps 150×150 if the subject is simple — crop to exactly that subject, and let the encoder work on something it can actually afford.
Expect a small image, not a small version of a big image. The search here spends the budget on dimensions before quality — a larger image at quality 55 beats a smaller one at 95, because the eye forgives artefacts more readily than missing resolution.
Getting a better result
Three things reliably help when the budget is tight:
- Crop before compressing. Every pixel you keep costs bytes. A tightly framed portrait at 10 KB looks far better than a full-body shot squeezed into the same space. The cropper hands its result straight to this tool.
- Start from the highest-quality original you have. Compressing an image that has already been through WhatsApp compounds the damage. Go back to the file straight off the camera.
- Prefer WebP if the form allows it. At the same file size WebP holds noticeably more detail than JPEG. Most official forms still want JPG, but it costs nothing to check.
