How it works
- Best quality that fits — it searches for the highest JPEG quality under your limit instead of guessing, so your photo stays as sharp as possible.
- Shrinks only when needed — if a photo can't fit even at lower quality, it's scaled down step by step, keeping its proportions.
- Safe for every form — “100 KB” is treated as 100,000 bytes, so the file is under the limit whether the site counts 1,000 or 1,024 bytes per KB.
- Private — ID photos and documents never leave your device.
Common size limits
- Passport and visa photos on many portals: 50–240 KB.
- Job and exam applications: often 20–100 KB for photos and 10–50 KB for signatures.
- Email-friendly photos: 200–500 KB.
Frequently asked questions
Will my photo look bad at 20 KB?
It's scaled to a smaller size so it stays clear — a 20 KB photo is usually around 300–450 px wide, which is what most forms expect anyway.
The form also needs exact dimensions — what do I do?
Fill in max width and height (for example 200 × 230). The photo is fitted inside that box first, then compressed to the size limit.
Can I compress a PDF to 100 KB?
Use Compress PDF — it works best on scanned documents.
