Signature and photo uploads on government and exam sites often cap files at 20–50KB. Small dimensions are the key: a signature rarely needs more than 400 px width.

How to do it

1. Open the Compress Image tool.
2. For signatures set width 400 and quality 0.7; for photos width 500 and quality 0.6.
3. Compress and check the size; lower values slightly if needed.

Tips

• Crop away empty margins first – it saves bytes.
• Scan signatures on plain white paper for smaller files.
