Frequently Asked Questions.
Everything you need to know about secure, private PDF editing in your browser.
Browser-based tools can reduce exposure when they process files locally. Lyonite’s current file workflows run in your browser rather than sending the file to Lyonite for processing. You should still review the output before sharing sensitive documents.
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 can include fields such as author, creator, producer, dates, document identifiers, XMP, and custom properties. To reduce that exposure, select the PDF in Lyonite’s metadata cleaner and download the rewritten copy. Review the result before sharing sensitive documents because visible content and some embedded objects are separate from document metadata.
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 browsers can handle many common PDF tasks without installing desktop software. Lyonite uses browser JavaScript and file APIs for its current workflows, so supported operations can run locally on the device. Desktop software can still be better for advanced editing, very large files, or specialized PDF features.
