Compress Image to 10 KB Online — Free
Exam forms, government applications and job portals in many countries ask for a passport-style photo of just 10 KB — sometimes stated as a range like 10 KB to 50 KB — and their upload boxes reject anything larger. Getting a normal phone photo down to 10 KB with a general compressor is painful, because most tools stop being useful long before the file gets that small. This free tool is preset to a 10 KB target and does the hard part automatically: it lowers the JPEG quality step by step and, when that is not enough, reduces the dimensions too, until the photo fits.
A 10 KB photo is small, so expect a soft, low-detail result — that is unavoidable at this size, and it is exactly what these forms accept, because they only display the photo as a tiny thumbnail on an admit card or application summary. Everything runs locally in your browser. Your photo is never uploaded to a server, which matters when the picture is an official ID-style photograph of you.
How to use
- Click the file box and choose the photo your form asks for.
- The target is already set to 10 KB — leave it, or type your form's exact limit (for example 20 or 50) instead.
- Press the Compress to Target Size button and wait while it tests quality levels and sizes.
- Read the result: if the target could not be reached at full size, the note explains that dimensions were reduced.
- Check the preview, then click Download Image and upload the JPEG to your form.
Frequently asked questions
Why do exam forms ask for a 10 KB photo?
Application portals store millions of photos and print them as small thumbnails on admit cards and result sheets. A 10 KB cap keeps their storage and printing cheap, so exam boards, universities and government job portals commonly specify 10 KB to 50 KB for the photograph.
Will my photo look blurry at 10 KB?
Softer than the original, yes. Ten kilobytes cannot hold much detail, so the tool reduces dimensions as well as quality. At the tiny size these photos are displayed and printed, the result is normally perfectly acceptable to the form.
The tool says the target could not be reached. What now?
That message means you are seeing the smallest version the tool can produce. Crop the photo tightly around the face before compressing — cropping away background removes pixels, which makes a small target much easier to reach.
Are my photos uploaded anywhere?
No. Everything happens on your own device in your browser. Your photo never leaves your phone or computer.
