Bring any photo down to 20KB while keeping it as sharp as that budget allows.
The limit is preset to 20KB. Choose your image and the tool searches for the highest JPEG quality that still fits underneath — rather than dropping to a fixed low setting and hoping.
Why forms ask for 20KB
Signatures, left thumb impressions and the strictest older portals. It is a tight budget for a photograph — at 20KB a colour portrait is right at the edge of where compression starts to show.
Commonly seen on: SSC signature uploads, India Post GDS signature, older state PSC portals.
Getting a good-looking 20KB file
- Crop first. Empty background still costs bytes. Cropping tight to the subject is free quality.
- Resize the pixels if the image is huge. Reduce the dimensions to something close to what the form displays, then compress to 20KB. The difference is dramatic on phone photos.
- Start from the original. Compressing an already-compressed file stacks the losses.
If your form wants a photograph at 20KB and it looks blocky, reduce the pixel dimensions first rather than compressing harder. A 300-pixel-wide image at 20KB looks far better than a 1200-pixel one at the same size.
If you overshoot
Many forms enforce a minimum as well as a maximum. If your file comes out well under 20KB and the portal complains it is too small, increase the size in KB to bring it back inside the band.
Frequently asked questions
How do I resize an image to 20KB?
Upload the image above, confirm the limit is set to 20KB, and download. The tool tests multiple quality settings and picks the sharpest one that still fits under 20KB.
Will the photo still look the same at 20KB?
That depends on how large the original is. Coming down from a 3MB phone photo to 20KB will lose some fine detail, but the tool keeps the highest quality that fits rather than dropping to a fixed low setting.
Is the result exactly 20KB?
It lands at or just under 20KB, which is what a maximum-size rule requires. If your form also enforces a minimum, the file will still sit comfortably inside the band.
Is my image uploaded anywhere?
No. Processing runs entirely in your browser on your own device. Nothing is transmitted, stored or logged, and the tool keeps working if you disconnect from the internet after the page loads.
