Why is my file rejected?
Check the supported format and the size or page limit shown in the upload area.
Can I drag more files after the first one?
Yes. Drag them into the selected-file area or use Add files.
Why is the preview still loading?
Large or complex PDFs can take longer to preview. You can still retry or check browser help.
Is the original file changed?
No. The site creates a new result and does not modify your local original.
