FAQ
Are my images uploaded to a server?
No. The image is processed locally in your browser with canvas APIs and is not uploaded to ToolNova.
Why is the final file size not exactly the target size?
Browser image encoding is approximate. The tool aims to get close to the target while keeping the image usable.
Which image formats are supported?
Most modern browsers support common JPEG, PNG, and WebP files. Support may vary slightly by browser.
