Frequently asked questions
Are my photos uploaded?
No. Normal processing happens locally in your browser, and your selected image is not uploaded to our server.
Can the tool always reach an exact KB size?
Not always. If the selected dimensions and minimum quality cannot meet the limit, the result clearly reports a close or impossible target.
Which image formats are supported?
The tools accept JPG, PNG, and WebP. JPG and WebP support quality-based size optimization; PNG is lossless.
Does it work on mobile phones?
Yes. The workflow is designed for touch, small screens, low memory, and modern mobile browsers.
