SwiftPDFLab - Edit PDF Text in your Browser - No Overlay

by•
SwiftPDFLab is a privacy-first PDF toolkit that lets you edit, merge, compress, convert, and sign PDFs entirely in your browser. Browser-based PDF toolkit with 100+ tools. PDF files and document contents are processed locally in your browser. Merge, split, compress, sign, redact, OCR, convert and more — plus edit supported existing PDF text directly, including font size and Bold or Italic where compatible genuine font faces are available. Unsupported edits are refused rather than guessed.

Hey Product Hunt 👋 I built SwiftPDFLab because most online PDF tools require uploading sensitive files to external servers — even for simple edits. SwiftPDFLab works differently. All PDF processing happens directly in your browser using client-side technology. Your files never leave your device, and many tools even work offline once loaded. There’s no signup, no usage limits, and it’s completely free. My goal was to create a fast, simple, and privacy-respecting alternative for anyone who works with PDFs regularly. I’d love your feedback — especially on performance, UX, and which tools you’d like to see next.
