Frequently Asked Questions
4 Q&AWhat PDF operations are supported?
Twelve tools: merge multiple PDFs, split a PDF into pages, edit content, compress size, convert to/from images, convert to/from Word, unlock password-protected PDFs, convert HTML to PDF, and convert between PDF and Excel.Are my PDF files uploaded to a server?
No. All twelve PDF tools run in your browser using PDF.js, pdf-lib, and SheetJS. Your documents never leave your device. The "100% private, browser-based" promise is enforced by the client-side architecture.How large a PDF can I process?
Browser memory is the limit. In practice PDFs up to about 100 MB work reliably for merge, split, and convert. Compression of large scanned PDFs may take a few seconds; very large files (500 MB+) may exhaust tab memory.Are these PDF tools free for commercial use?
Yes. There is no signup, no watermark, no per-file fee, and no usage limit. You can use them for personal, business, or client work without restriction.How to Use These PDF Tools
