Pick a photo, set the limit (pre-filled with 10 KB), and download the compressed copy. Free, private, no sign-up.
Very small limits like 10 KB are common for signature, stamp, thumbnail and ID-number uploads on application forms. At this size the image is usually small in pixels as well, so a simple, high-contrast picture works best.
Tip: Crop away empty space first, because a tighter image needs fewer pixels and keeps more detail at 10 KB.
Always check the exact size, format and dimensions your upload form asks for - requirements differ between websites. Need a different pixel size? Use the image resizer.
Choose your image, keep the target at 10 KB, and click Compress. The tool lowers the quality step by step (and the pixel size only if needed) to find the best-looking result that still fits under 10 KB, then you download it.
No. Compression happens inside your browser on your own device, so the image is never sent anywhere or stored.
The tool keeps the highest quality that fits under the limit. If the original is already small or simple, the result can land well under 10 KB, which is accepted by almost every upload form.
Some detail is lost whenever a file is made smaller. For JPG and WebP the loss is usually hard to notice at moderate reductions; very small targets such as 10-30 KB will look softer.
JPG works everywhere and is the safe choice for forms and portals. WebP is usually smaller at the same quality but not every upload form accepts it.
Yes. The PNG is converted to JPG or WebP (which can be reduced precisely). Transparent areas become white in JPG.
