About this tool
Thirty kilobytes is a common upload ceiling for signatures and low-resolution passport-style photos on Indian government and university portals. It is small enough to be strict, but generous enough to preserve legibility. This landing tunes the compressor to aim close to 30 KB, and gently resizes only when the source is far larger than the target size can accommodate. Everything happens locally in your browser tab.
FAQ
For a small on-portal photo, usually yes. For a full passport photo, aim for ~50 KB.
Boost contrast in the source scan before compressing; darker input holds up better at 30 KB.
No account is required.
Yes, standard JPG and PNG outputs are compatible with virtually all portals.
No. The 30 KB target compression runs locally in your browser.
More about this tool
How it works
- Add one image that needs to land near about 30 KB.
- The tool aims for about 30 KB for signature and ID photo ceilings. Results are approximate, not exact bytes.
- Check the preview. If the target is unrealistic, crop or resize the source and try again, then download.
Tips
- Aim near 1200 px on the long edge — Oversized sensors waste attempts before compression starts helping.
- Neutral lighting helps — Noisy night photos need more bits; daylight portraits compress cleaner.
- Compare with 50 KB — If text or edges look crunchy, jump to Compress Image to 50KB.
- One subject per frame — Busy backgrounds soak bytes that could protect faces.
Supported formats
Input: JPG, PNG, WebP, AVIF. Output: JPG for photos, PNG when transparency is needed.
