How to compress an image to 40KB
- Choose your photo or drop it into the box.
- Keep the target at 40 KB, or change it to any size you need.
- Check the preview, then download the new file.
The tool tries the best JPEG quality that fits under your limit. If the quality alone is not enough, it reduces the image dimensions a little at a time until the file fits.
Why 40KB?
40KB is often asked for on application forms that want a small passport-style photo. It leaves enough room for a clear face when the background is plain.
Questions
Is 40KB good for a passport-style photo?
Yes for a small photo with a plain background. Busy scenes look softer.
How do I keep it sharp?
Crop closer to the face so more pixels go to the important part.
Is my image uploaded?
No. Everything runs in your browser.
Can I use a different size?
Yes. Type any number in the target box.
