FAQ
Questions before you begin
When does the free quota return?
Each successful file drops out of the count 24 hours later. You do not need to wait until midnight.
Do failed files use quota?
No. A file counts only after the browser successfully creates its result.
Are images uploaded?
No. Conversion, crop and compression run in this browser. Use the separate local image OCR tool when you need to extract text.
