Are my uploaded images secure?

Absolutely. Our tool operates entirely within your browser, which means your image files never leave your computer and are not uploaded to our servers. Your privacy is 100% protected.

What file formats does this tool support?

You can upload images in PNG, JPG/JPEG, and WebP formats. When exporting, you can also choose to save the image in any of these three formats.

What is the maximum size for resizing?

To ensure stable browser performance, we have set the maximum width and height to 8000 pixels. This is sufficient for the vast majority of high-resolution use cases.

Why can't I adjust the quality of PNG images?

PNG is a "lossless" compression format, meaning it retains all original image data to ensure the highest quality. Therefore, there is no "quality" slider like there is for JPG or WebP. If you need a smaller file, consider converting it to WebP.
