Frequently asked questions
What does a PDF's metadata contain?
The title, author, subject, keywords, creation and modification dates, and the software that created the file. It is visible in the document properties.
Are my files uploaded to a server?
No. Processing happens entirely in your browser, on your device. No file is uploaded or stored. You can check: once the page has loaded, disconnect from the internet and the tool still works.
Is there a file size or number limit?
No. Since nothing goes through our servers, there is no quota. The only limit is your device's memory: a computer handles very large files more easily than a phone.
Is it really free?
Yes. No sign-up, no watermark added to your documents and no usage limit.
