80KB is a peculiarly specific upper bound enforced by several government and institutional upload forms. Japan's My Number Card application portal requires 20–80KB JPEG photos, and many Asian visa and university portals enforce the same limit.
Instead of guessing quality sliders, ImageMint's Target Size tool binary-searches the exact JPEG quality that fits under 80KB while preserving as much facial or document detail as possible.
How to Compress
- 1
Upload Your Image
Drop a JPG, PNG, or HEIC photo. Your file stays on-device.
- 2
Set Target to 80KB
Enter 80 in the target field and pick JPEG output for best form compatibility.
- 3
Download the Result
Confirm the file is between 20KB and 80KB before submitting to the form.
Tips
- My Number Card photos must be 480-6000px wide. Resize before compressing if needed.
- If output is below 20KB, raise quality slightly — many portals reject files that are too small.
- Strip EXIF metadata before submitting: extra bytes can push you over 80KB for nothing.
FAQ
Why 80KB exactly?
Multiple Asian government portals (Japan, Taiwan, Korea) historically cap ID photos at 80KB to keep server storage predictable.
Is 80KB enough for a clear ID photo?
Yes, at typical ID dimensions (600x800) the result remains clearly legible for face-match systems.
Can I use WebP?
Only if the form explicitly accepts it. Most government forms require JPEG.
