Resize image to 20KB — FAQ
How do I reduce my photo size to 20KB?
Add your photo above, keep “Target size” at 20 KB and the format as JPG, then press the Resize button and download. The tool automatically finds the best quality under 20 KB.
How do I resize my signature to 20KB?
Scan or photograph your signature on white paper, crop it, then add it above and press the Resize button. The 20 KB target is already set.
Which forms need a 20KB photo or signature?
Many Indian exam and job portals (SSC, banking, railways, state recruitment) ask for photos or signatures between 10 KB and 50 KB. Always check the exact limits and dimensions in your form’s instructions.
My form also needs exact pixel dimensions. Can I do both?
Yes. Switch to the “By pixels” tab, enter the width and height from your form, and keep the 20 KB target size.
Why is my image still above 20KB?
Make sure the format is JPG or WebP. PNG is a lossless format, so the target size cannot be applied to it.
Are my photos uploaded to a server?
No. Everything happens in your browser, so your photos never leave your device.
