Frequently asked questions
How does the JPEG Compressor work?
It re-encodes your image using the HTML Canvas API at a lower quality setting, producing a smaller file that looks nearly identical. Everything happens locally in your browser - nothing is uploaded.
Is my image uploaded to a server?
No. Every ImageEditPro tool processes your image directly inside your browser using JavaScript and the Canvas API. Files never leave your device, so your photos stay 100% private - even when you're editing sensitive documents or personal photos.
Is it really free? Any watermark or signup?
Yes, completely free. No account, no sign-up, no watermark, no daily limit. ImageEditPro is supported by unobtrusive ads so you can use every tool as many times as you need without paying.
