Frequently Asked Questions
Are my confidential contracts or tax PDFs uploaded to any remote server?
No. All PDF operations (merging, splitting, compressing, rasterizing, and signing) run 100% locally in your web browser using WebAssembly and client-side Web Workers. Your files are never sent over the internet and never touch a cloud disk.
How do I extract specific page ranges or burst a PDF into single pages?
Open Split PDF (/pdf/split), load your document, and enter your desired page numbers (e.g. '1-3, 5, 8-12') or select individual thumbnail pages visually to download extracted sections or individual pages in a ZIP archive.
Can I combine multiple PDFs with different orientations or page sizes?
Yes! Merge PDF (/pdf/merge) allows you to drag and drop multiple documents together, reorder files or individual pages visually, and export a clean consolidated PDF document.
How does PDF compression reduce file size while preserving text legibility?
Our in-browser PDF compressor downsamples embedded bitmap images (with selectable DPI options like 150 DPI for screens or 72 DPI for email) and cleans redundant font subsets while preserving crisp vector text rendering.
Are digital signatures added using Sign PDF legally compliant?
Our Sign PDF (/pdf/sign) tool renders electronic signature visuals and audit stamps directly into the PDF coordinate system. Because documents are processed locally, your sensitive signatures are never stored on external databases.
