- Choose the photo that must be under 30 KB.
- Keep the 30 KB target, or type the exact limit.
- Click Compress image and wait while it finds a fit under 30 KB.
- Check the face is clear in the preview, then download the JPG.
Options explained
- Choose a target file size
- Starts at 30 KB. Pick a different quick size or type the exact limit in KB. Sizes use 1024 bytes per KB.
Limits and supported files
JPG, PNG and WebP images. The result is always a JPG. See-through areas in PNG or WebP become white.
A target size is an aim. A detailed photo may need fewer pixels to fit, and very small targets can make faces or text hard to read.
Photos above about 16.7 million pixels are reduced to that size first. Choose up to 100 images at a time.
Tested in Chromium, Firefox and WebKit.
Questions
Will a passport photo look good at 30 KB?
Usually, yes. A head-and-shoulders photo keeps enough detail at 30 KB for most forms. Check the preview before you upload it.
My form asks for 20 to 50 KB. Which target should I pick?
Pick 30 KB or type 45. The tool stays just under the number you enter, so the result is inside the range.
Does the 30 KB result keep the photo's shape?
Yes. If the pixels need to shrink, width and height shrink together, so the photo is not stretched.
Is my photo sent anywhere when I compress it to 30 KB?
No. Your browser does the work on this device, so the photo is never uploaded.
