Which browsers are supported?
Use a current version of Chrome, Edge, Firefox or Safari.
Does it work on phones?
Yes, but large files are usually easier to process on a computer with more memory.
Why is preview unavailable?
The browser may lack memory, block a component or be using a damaged PDF.
Can extensions interfere?
