Why use ImgZero for Free Private PDF Tools?
Frequently Asked Questions
Are my documents uploaded to a remote server?
No. All ImgZero PDF tools operate entirely on your device using client-side JavaScript, WebAssembly, and Web Workers. Your files, camera frames, and text never leave your browser.
Which PDF tools preserve selectable text versus raster images?
HTML to PDF, PDF Organizer, PDF Merge, and PDF Split preserve crisp vector text and document structures. PDF Compressor uses a safe raster mode specifically intended for scanned image documents.
Does ImgZero store or track any document data?
Never. No filenames, document contents, extracted text, passwords, or thumbnails are ever sent to analytics, servers, or session replay.
100% Client-Side Privacy Guarantee
Your files stay on your machine. No server uploads and no file-content tracking.
