Frequently Asked Questions.
Everything you need to know about secure, private PDF editing in your browser.
Yes, when using browser-based tools like Lyonite. Your files are processed entirely in your browser using WebAssembly technology — they never leave your device or get uploaded to any server. This is the safest way to edit PDFs online because your data stays completely private.
Use a smart compression tool that optimizes images and removes unnecessary data while preserving text clarity. Lyonite's PDF compressor lets you choose compression levels — from minimal (best quality) to maximum (smallest file size) — so you control the balance between quality and file size.
Absolutely. Lyonite lets you merge multiple PDFs into one document without creating an account. Just upload your files, arrange them in order, and download the combined PDF. No email required, no watermarks added.
PDF metadata includes hidden information like author name, creation date, and editing history. To remove it, use a metadata removal tool — upload your PDF, click remove, and download a clean version. This is important for privacy when sharing documents publicly.
Splitting a PDF divides it into multiple separate files (e.g., a 10-page PDF becomes 10 single-page PDFs). Extracting pages creates one new PDF containing only the specific pages you select. Both are useful depending on whether you need individual files or a curated document.
Modern browser-based tools using WebAssembly can match desktop software for most common tasks — compression, merging, splitting, and editing metadata. The main advantage is convenience: no installation, works on any device, and with tools like Lyonite, your files stay completely private since processing happens locally.
