About this tool
A 10 KB limit is one of the smallest you will see on a form. It usually applies to a signature or a tiny thumbnail, so the picture needs very few pixels as well as strong compression. Choose your photo and this tool finds the highest quality that still fits under 10 KB.
How to use it
- Choose your photo.
- Check that the target size says 10 KB.
- Press Resize & Compress.
- Download the file and use it on your form.
How to get under 10 KB
At this size the number of pixels matters most. A picture about 150 pixels wide can fit in 10 KB, while a full phone photo cannot. If you have a signature, use black ink on plain white paper and crop close to the writing.
The tool tries to keep the picture as large and clear as it can while staying under 10 KB. If the result looks too rough, use the resize tool to set a smaller width and height first, then compress again.
Common questions
Will the file be exactly 10 KB?
It will be 10 KB or a little smaller. The tool picks the best quality that stays under the limit.
The result is still too big or too blurry. What now?
Set a small width such as 150 pixels first, then try again.
Is my photo uploaded?
No. The photo is processed inside your browser and never leaves your device.
Can I use this for a signature?
Yes. A dark signature on plain white paper compresses very well, so it stays readable even at 10 KB.
