PDF parsing keeps the document in memory. Limits of 25 MB per PDF, 60 MB per batch and 300 pages help bound memory on mobile devices. Rendering is limited to 16 megapixels per page, and exports to 120 MB. Very complex files can still exceed device memory.
Added text supports the Latin characters available in Helvetica, Times and Courier. Unsupported characters are rejected. Original embedded fonts are preserved.
Questions and answers
Are my documents uploaded?
No. Processing and preview run in your browser. Reloading or starting again releases the session. Nothing is saved to a user account.
