Frequently Asked Questions
Are my PDFs uploaded to a server when I use these tools?
No. Every PDF tool on EveryFreeTool runs entirely in your browser using JavaScript and WebAssembly. Your files never leave your device, are never stored on any server, and are never accessible to anyone but you. This makes our tools safe for confidential documents, legal files, and sensitive business materials.
Is there a file size limit for PDF processing?
Since processing happens in your browser, the practical limit depends on your device's available memory. Most modern computers and phones can handle PDFs up to 100MB without issues. For very large PDFs (200MB+), performance may vary depending on your device. There are no artificial limits imposed by our tools.
Can I merge PDFs with different page sizes and orientations?
Yes. The merge tool preserves each page's original size and orientation. You can combine letter-size documents with A4 pages, portrait with landscape, and even pages with different margins. The resulting PDF maintains every page exactly as it was in the original files.
How does PDF compression work without losing quality?
Our PDF compressor offers multiple compression levels. The light setting recompresses images at high quality and removes redundant data, typically reducing file size by 30-50% with no visible quality loss. Medium and heavy compression further reduce image quality for smaller files. You can preview the result before downloading.
Can I password protect a PDF so it cannot be printed or copied?
Yes. The Protect PDF tool lets you set both an open password (required to view the document) and permissions passwords that restrict printing, copying text, and editing. It uses AES-256 encryption, which is the same standard used by banks and government agencies.
