The 500KB sweet spot

500KB is generous enough to keep near-original quality while still being light for the web and email. The tool targets just under 500KB at maximum quality, so your image stays detailed while loading fast and slipping under common attachment limits.

Frequently asked questions

Will a 500KB image still look high quality?

Yes. 500KB is enough headroom that most photos keep near-original clarity, especially at typical screen and print-preview sizes.

Do I lose the original?

No — the tool creates a new compressed copy for download and leaves your original file untouched.

Is anything uploaded?

No. Compression is 100% local to your browser.
