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.

Questions

Is 15 KB enough for a face photo?

For a small passport-style photo, usually. A large photo may need fewer pixels to fit. Check that the face is clear in the preview.

My form asks for 10 to 20 KB. Will 15 KB work?

Yes. 15 KB is inside that range, and the tool stays just under the number you enter.

Will my signature still be readable at 15 KB?

Usually, yes. A signature on plain paper has little detail, so it fits well. Crop away extra blank space first if you can.

Is my photo sent anywhere when I compress it to 15 KB?

No. Your browser does the work on this device, so the photo is never uploaded.
