Help & clarification
Frequently Asked Questions
Will my JPG lose quality?
At quality 70–85 the difference is practically invisible while the file is much smaller. If a file can't be made smaller, your original is kept unchanged.
Does it keep my file format?
Yes. Your images stay JPG — only the file size changes.
Are my images uploaded to a server?
No. Every operation runs locally in your browser using the HTML5 Canvas engine. Your files never leave your device, so they stay completely private.
Is this tool free to use?
Yes — it's completely free with no sign-up, no watermarks added to your output and no daily limits.
