Frequently Asked Questions
Here are some common questions about our PDF tools. If you have any other questions, feel free to contact us.
Q. Are my files safe?
Yes! Most of our tools process your files locally in your browser. This means your files never leave your device. For tools that require server processing (like AI Summary), files are encrypted during transfer and deleted permanently immediately after processing.
Q. Is it really 100% free?
Yes, our basic PDF tools are completely free to use without any hidden fees. You can process your files without restrictions.
Q. Is there a file size limit?
For local processing tools, the limit mainly depends on your browser's memory capabilities (usually up to 100MB works well). For server-based tools, there is a strict 50MB limit per file.
Q. Can I use it offline?
While you need an internet connection to load the website initially, most tools that process files locally will continue to work even if you lose your internet connection.
