About this tool

Compress Image to 100KB

Many websites and application forms only accept images under 100 KB. This tool shrinks your photo below 100 KB automatically: it finds the highest JPG quality that fits, and only reduces the dimensions if the quality alone isn't enough. That keeps the picture as sharp as possible.

A 100 KB limit is common for photos and documents on college, scholarship and job portals. If your form also sets a minimum size or exact dimensions, click Change and enter them, or use one of the exam pages below.

Everything happens in your browser, so your photo is never uploaded. It works on Android, iPhone and desktop.

  • Always under 100 KB

    The file is checked against 100 KB before you download it.

  • Best quality that fits

    Quality is lowered only as much as needed, then the size if necessary.

  • Any image format

    Upload JPG, PNG or WebP. You get a JPG that every form accepts.

  • No upload

    Works offline once the page has loaded. Your photos stay on your device.

Upload the photo on this page. It is compressed to under 100 KB straight away at the best quality that fits. Check the size shown next to the green tick, then click Download.

Usually very little. 100 KB is enough for a clear photo at a normal size, so most images only need a slightly lower JPG quality.

Click Change above the upload box and type the size range and dimensions from your notification. The tool then makes a JPG that meets those numbers instead. Always check the latest official notification before you upload, because rules can change between years.

No. The photo is resized and compressed inside your browser, on your own phone or computer. It is never uploaded to our servers, so your photo, signature and ID documents stay private.
