Frequently asked questions
Are images sent to the cloud?
No. The browser File, Image and Canvas APIs process the image on your device.
How do I handle multiple images?
Use this page for one carefully adjusted image; use the image batch converter for multiple files and ZIP download.
Why does the output size change?
Format, dimensions and quality settings affect the Blob size. Lossy JPG and WEBP quality also changes file weight.
