Handling very strict 100KB upload limits
Very strict forms fail uploads because they are built for tiny assets, not full camera photos. A platform may cap files at 100KB for profile images, exam portals, government IDs, or legacy document systems. If your image is even slightly above the limit, the form rejects it, often with a confusing message that gives no clear fix.
Typical limits in these environments range from 50KB to 200KB, with 100KB being especially common for avatars and signature-style images. Raw photos from phones are usually far above that threshold, even before editing. That is why users repeatedly retry uploads and still get blocked, despite having a valid image format.
Compressing under 100KB solves this by prioritizing essential visual detail and removing non-critical data. You get a file that can pass strict validators and upload faster on any connection. Privacy is still protected: processing happens entirely in your browser on your own device, so your image is never sent to a remote server or database.

Frequently asked questions
Can a photo still be usable under 100KB?
Yes for many profile, ID, and signature use cases, especially when the display area is small. Extremely detailed images may need stronger quality reduction.
Why do some sites enforce 100KB exactly?
Older systems and high-volume portals use strict limits to control storage and improve speed for millions of records.
Will this work for passport-style uploads?
It can help meet file-size requirements, but you should still check the portal's dimension and background rules before final submission.
Do my files leave my device?
No. Compression runs locally in your browser and no image is uploaded or stored on our servers.
