Frequently Asked Questions

Do you store the images I upload?

No. All image processing (compress, resize, crop, convert, etc.) happens in your browser using the Canvas API. No image data ever leaves your device.

Which image formats are supported?

Most tools support JPG, PNG, WebP, GIF, BMP, SVG and TIFF. The output format depends on the specific tool — you can usually choose JPG or PNG.

Will compressing images reduce their visual quality?

We use quality-optimised compression. You can control the quality level with the Quality slider. JPG compression above 70% is generally indistinguishable to the human eye.

Can I process multiple images at once?

Yes — tools like Batch Resize and Compress Image accept multiple files at once and package the results in a ZIP download.

Why is WebP a good format?

WebP typically produces files 25–35% smaller than equivalent JPG or PNG images at the same visual quality, making it ideal for websites and apps.
