PrivaX is a privacy-first Chrome extension for image & PDF processing. Everything runs 100% locally via WebAssembly — no uploads, no cloud, no tracking.
Compress JPEG/PNG/WebP/AVIF, convert formats, batch 50+ files, strip EXIF metadata. For PDFs: compress (3 modes), split, merge with drag-drop reorder, convert pages to HD images, combine images into PDF.
Open source, free forever.
Hey PH! 👋
I built PrivaX out of a real workplace problem.
I work in banking, and my documents are strictly confidential before they go into production. Every time I needed to compress images or split/merge a PDF, the only options were online tools that upload your files to their servers. That's a hard no when you're handling financial materials.
So I thought — what if everything just happened locally?
PrivaX processes files 100% in your browser using WebAssembly. Not "we delete your files after processing" — literally zero network requests. Don't trust me? Open DevTools → Network tab while using it. You'll see nothing. 🔍
What it does:
Image compression: PNG 4.2MB → 890KB (79% reduction), batch 50+ files, supports JPEG/PNG/WebP/AVIF
PDF compression: 4 modes from metadata-only cleanup to aggressive image recompression
PDF split & merge with drag-and-drop page reorder
PDF to HD images: export pages as PNG/JPG/WebP at 72/150/300 DPI
Images to PDF: combine into A4/Letter with customizable margins and orientation
EXIF metadata stripping (GPS, camera info, all sensitive data)
All with no visible quality loss, works fully offline
It's completely free.
I'd love your feedback:
