About Image Compressor to 15KB

This image compressor makes your photo smaller than 15 KB so it fits signature and photo fields on forms. It first lowers the JPG quality step by step to find the best quality that still fits. If the picture is so large that quality alone is not enough, it also reduces the pixel size a little until the file is under 15 KB.

As a guide, a normal photo that must stay under 15 KB ends up at roughly 200 x 270 pixels. Crop the photo to the shape the form wants before you compress it. A tight crop leaves more bytes for the face.

Everything runs inside your browser. Your pictures are not uploaded to a server, so private photos and ID pictures stay on your device.

Frequently asked questions

How do I compress an image to 15 KB?

Choose your image above and press Compress. The tool finds the highest quality that is still under 15 KB and gives you the file to download.

Will my photo still look good at 15 KB?

Usually yes. A photo of about 200 x 270 pixels looks clean at this size. Very large photos are resized a little so they do not turn blocky.

My file is still above 15 KB. What can I do?

Crop the picture to the part you need, then compress it again. Cropping removes pixels, so more of the 15 KB budget goes to the part that matters.

Can I compress many images to 15 KB together?

Yes. Select as many files as you like. Each one is compressed to 15 KB or less, and you can download them together as a ZIP.

Are my files safe?

Everything runs inside your browser, so your files stay on your device and are never uploaded.
