There is no PaperStack upload quota because files are not sent to our servers. Practical limits come from your browser and device memory. Very large PDFs or spreadsheets may fail on a phone.

No. Tools produce a new result for you to download. Your original stays on disk until you choose to replace it.

Some tools, such as Merge PDF and JPG to PDF, accept multiple files in one session. Others work on one document at a time. Check the tool page for details.

Refresh the tab and try again with a smaller file, or unlock a password-protected PDF first. If it still fails, email support@paperstack.in with the tool name and browser — do not send the confidential file unless we ask.
