Compress image to 10 KB
Get any photo under 10 KB without guessing quality settings. Drop it in, and the tool finds the best version that fits, right on your device.
When you need 10 KB
- Signature uploads on exam and recruitment forms
- Tiny thumbnails and favicon-sized previews
- Very strict legacy upload fields
What to expect
10 KB is extremely tight for a photo: expect roughly 250–400 px wide. Scanned signatures on white paper fit far more easily than photos; crop away empty margins first.
Other sizes: 20 KB · 30 KB · 50 KB · 100 KB · 150 KB · 200 KB · 300 KB · 500 KB · 1 MB · 2 MB
Questions
How do I compress a photo to 10 KB?
Add the image above; the target is already set to 10 KB. The tool finds the highest JPEG quality that fits under 10240 bytes, shrinking the width only if needed, then you save the file.
Why is my image under 10 KB but smaller than expected?
The search steps in quality increments and always stays under the limit, so the result is usually a little below the target. That leaves margin for forms that count KB as 1,000 bytes.
My form also requires exact pixel dimensions. What do I do?
Enter the required width and height as max width and max height before adding the image. The tool resizes first and then fits the size target, which gives better quality than letting it shrink on its own.
Is my photo uploaded?
No. The compression runs in your browser with WebAssembly; the file stays on your device. That matters for ID photos and signatures.
