How it works
- 1Drop your image — everything runs in your browser, nothing is uploaded anywhere.
- 2We binary-search JPEG quality to find the highest setting that still lands under 500KB — generous enough that compression is rarely visible.
- 3Dimensions stay untouched in almost all cases; only extremely high-resolution originals need any downscaling.
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
- Which portals ask for a 500KB image limit?
- 500KB is a common cap for photo uploads on job portals and some visa/document systems — loose enough that most smartphone photos only need light compression to clear it.
- Does 500KB compression look bad?
- No — at this size compression is usually invisible to the eye. The tool searches for the highest JPEG quality that still fits under 500KB rather than applying a fixed setting.
- 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.
