Get any photo in KB, at the exact limit you need
Online forms rarely say "make it smaller" - they give a number: 20 KB, 50 KB, 100 KB, 200 KB. This tool works to that number. Enter the limit in KB, choose your photo, and it finds the highest quality that fits. If quality alone is not enough, it reduces the width and height only as much as needed, so the face or document stays as clear as possible.
Common KB limits and what they are for
- 10 to 20 KB - signatures and thumbnail photos on exam and recruitment forms. See compress to 10 KB and 20 KB.
- 20 to 50 KB - passport-style photos on government and university portals. See 30 KB and 50 KB.
- 100 to 300 KB - ID proofs, certificates and scanned documents. See 100 KB, 200 KB and 300 KB.
- 500 KB to 1 MB - visa photos, websites and email. See 500 KB and 1 MB.
Why KB and pixels are different
KB measures how much storage the file uses; pixels measure its width and height. A form may set both, for example "200 x 230 pixels, under 50 KB". If it gives pixel sizes, resize the photo to them first with Resize Image, then bring it under the KB limit here. If it only gives a KB limit, this tool is all you need.
Check before you submit
Some portals count 1 KB as 1,000 bytes instead of 1,024, so aim a little below the limit - for example 48 KB for a 50 KB cap. Open the downloaded photo once to make sure it still looks sharp and is the right way up.
