When you need this
Online application forms, government portals, university admissions, job sites and e-mail attachments often reject files over a strict limit. FileNorm finds the best quality that fits under that limit, so your document is accepted the first time.
Frequently asked questions
- Why do some portals require exactly 100KB?
- Portals like CursusUp, DGSN, and many other Moroccan concours and government sites enforce a strict 100KB cap on ID/identity photos to keep their systems fast and predictable across huge numbers of applicants. It's not a soft guideline — files over the limit are rejected outright, so hitting the number exactly matters.
- Will compressing to 100KB reduce image quality noticeably?
- We binary-search the highest JPEG quality that fits your target, and only downscale dimensions as a last resort. At 100KB most portrait-style ID photos stay clearly legible; very high-detail or high-resolution originals may show mild softening.
- What file formats does this accept?
- JPEG, PNG and WebP as input. Output is JPEG (PNG transparency is composited onto white).
- Is my photo uploaded to a server?
- No. All compression happens in your browser via WebAssembly. Your file never leaves your device.
- Is it really free?
- Yes — no account, no watermark, no limit on the number of files.
