Frequently asked questions
Is the folder uploaded?
No. Folder drag-and-drop only adds the local File objects exposed by the browser.
Which images are supported?
Common PNG, JPG, WEBP and static GIF frames supported by the browser can be processed. Transparency and animation vary by output format.
Is the ZIP generated on a server?
No. Canvas, File and JSZip generate each Blob and the ZIP in the browser.
