Frequently Asked Questions
- Are these PDF tools safe to use with confidential documents?
- Yes. Every PDF tool on brevio runs entirely in your browser using pdf-lib via WebAssembly. Your files never leave your device — there is no server upload.
- Do I need to create an account to use these PDF tools?
- No. All tools are free and require no signup, account, or email address.
- Do the tools work on large PDF files?
- Yes, with practical limits. Processing runs in your browser's memory. Files up to 200MB work on most modern devices; very large files may be slow on older hardware.
- Can I use these PDF tools offline?
- Once loaded in your browser, the tools work offline. The processing runs locally using WebAssembly — no internet connection is required after the initial page load.
