PDFCatalyst
Browser-only PDF editor — your files never leave the tab
Edit PDFs entirely in your browser — no upload, no signup. Merge, split, sign, fill forms, redact, edit text, compress, watermark, image↔PDF. 24 tools. Free. Built with pdf.js + pdf-lib + IndexedDB. Your files literally never leave the tab. EN + VI.
Hey Product Hunt 👋
Mark here — solo maker. Why I built this:
Every "free online PDF editor" uploads your file to their server. The privacy policies all say "deleted in 1 hour" but you have to trust them. PDFCatalyst is the version where "didn't upload" is verifiable in DevTools, not promised in a policy.
24 tools, all client-side: merge, split, compress, sign (draw/type/upload), fill AcroForms with a saved profile that auto-fills name/address/KYC across any form, redact, edit existing text, watermark, page numbers, image↔PDF, deskew, QR stamp. EN + VI.
Stack: React 19 + pdf.js + pdf-lib + IndexedDB. ~150 KB initial; heavy engines lazy-load per tool.
Honest limits: encrypted PDFs come back rasterised after unlock (pdf-lib quirk). Files >100 MB hit browser memory limits. No server-side OCR.
Free, no signup, no paywall. Would love feedback — especially on the autofill profile flow, and any Vietnamese government form that trips up the AcroForm detection.
Thanks 🙏
