Frequently asked questions

Do the images need to be the same size?

For accurate pixel diffs, yes - resize one to match the other first. For visual comparison the tool auto-fits both images to the same preview size.

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.
