The world's most-requested JPEG size
If a form specifies both a format and a size, 'JPEG, under 100 KB' is far and away the most common combination. It's the default for official systems that need a clearly legible photo but can't afford to store large files across millions of applicants.
- University and college admission portals.
- Tax filing and government e-service uploads.
- Recruitment and HR document systems.
- Exam and licensing registration forms.
How this page guarantees a compliant file
The output is always a real .jpg, and the tool works down from high quality until the file fits under 100 KB — first by adjusting compression, then by reducing dimensions if it has to. That means you get the sharpest possible photo that still meets the limit, without trial and error.
100 KB is comfortable for JPEG at typical document dimensions (around 600–1200 px), so ID and passport-style photos stay clear enough to pass a manual check. The preview lets you confirm legibility before you download and submit.

Frequently asked questions
My form says 'JPEG only, max 100 KB'. Will this work?
Yes — that exact requirement is what this page is built for. The output is a standard JPEG under 100 KB that any upload form will accept.
Is my image uploaded to a server?
No. Compression happens entirely in your browser using the Canvas API — your image never leaves your device, which is also why it's instant.
What if my image can't reach 100 KB?
The tool first lowers the compression quality, and if that's not enough it gradually reduces the dimensions until the file fits under 100 KB. Extremely detailed images may lose visible quality at very small targets — the preview shows you exactly what you'll get.
