How to compress a photo to 20 KB
Many application forms, especially exam and government forms in India, ask for a photo under 20 KB. A photo from a modern phone can be several megabytes, so it has to be compressed before upload. This tool creates a JPG at or below 20,000 bytes. It adjusts JPG quality first and reduces the pixel dimensions only if the file is still too large, so the photo keeps its natural shape.
Use this page when the form states 20 KB as the limit. If the limit is looser, the 50 KB or 100 KB pages keep more detail because they need less compression. The 20 KB setting controls file size only. Check the notification or form for the required pixel size.
To resize image to 20 KB here, choose your photo, select Prepare and then download the JPG. That is two clicks after you pick the file. The 20 KB limit and JPG format are already set, so you do not need to change any settings.
Tips for a sharp 20 KB photo
A 20 KB file has little room for detail, so start with a clear, evenly lit photo. Stand in front of a plain background, keep the face centered and avoid heavy filters. A tight headshot, with the face filling most of the frame, usually looks better than a wide group shot squeezed into the same number of bytes.
Before you download, open the preview at full size and check the eyes, edges and any text. Some softness is the trade-off of a 20 KB limit. Export a fresh copy from your camera app rather than compressing an already compressed image, since each pass removes a little more detail.
Size, privacy and devices
The tool runs in your browser on a phone or computer. Your photo is processed on your device, is never uploaded to a server and is not stored or shared. No sign-up or account is needed, and the downloaded file has no watermark.
KB here means 1,000 bytes, so the limit is 20,000 bytes. Some Indian portals count 1 KB as 1,024 bytes, which would be 20,480 bytes for 20 KB. This output stays under 20,000 bytes, so it fits under both conventions.

Will the photo lose quality at 20 KB?
Some detail can soften at this size because the JPG is compressed more. Check faces and text in the preview before downloading.
