Why do so many forms ask for 100KB?

It's small enough to store and process cheaply at scale, but large enough to keep a usable photo — so portals settled on it as a standard limit.

Will the photo still be accepted?

Yes — the image stays in its original dimensions and format (unless it needs slight downscaling), just under the 100KB size cap the portal requires.

Compress Image to 100KB

Shrink an image to exactly 100KB — the most common upload limit for visa, exam and job portals.

processed on your device — never uploaded

100KB is the single most requested image size on the web: visa applications, university exam portals, job sites and countless government forms all reject photos larger than 100KB. Drop your image and it's compressed to fit on the first try — no back-and-forth.

It all happens in your browser, so your document photo is never sent to a server.
