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
- Is my image uploaded to a server?
- No. All compression happens in your browser via WebAssembly. Your file never leaves your device.
- Will the quality be bad?
- We binary-search the highest JPEG quality that fits your target, and only downscale dimensions as a last resort.
- What formats are supported?
- JPEG, PNG and WebP as input. Output is JPEG (PNG transparency is composited onto white).
- Is it really free?
- Yes — no account, no watermark, no limit on the number of files.
