Compress an image to 10KB — or any exact size
Reduce a JPG, PNG or WebP to 10KB, 20KB, 50KB — whatever a form demands. Free, no sign-up, and 100% private: your images are compressed in your browser and never uploaded.
imageto10kb is a free image compressor that hits an exact file-size target instead of a vague quality slider. It is built for the millions of exam and job-application forms across India and Pakistan that demand a photo or signature under a strict KB limit — compress an image to 10KB, 20KB or 50KB, drop it in, and download a file that fits, without your picture ever leaving your device. Got several photos to do? Use the bulk image compressor to resize many at once and download them as a ZIP.
How to compress an image to an exact size
- Choose your image. Drop a JPG, PNG or WebP onto the box, or click to select one from your device.
- Set the target size. Enter the KB size you need — 10, 20, 50 — or tap a preset. If your form specifies a range (like 20–50KB), set the minimum too. Lock exact dimensions if a form requires them.
- Compress in your browser. imageto10kb finds the highest quality that stays under your target, entirely on your device.
- Download. Save the compressed image and upload it to your form.
