PrivaX is a privacy-first Chrome extension for image or PDF processing. Unlike most online tools, your files never leave your device.
Built with WebAssembly, everything runs 100% locally in your browser ā no uploads, no cloud processing, no tracking, no network requests.
Compress JPEG/PNG/WebP/AVIF images, convert formats, batch process 50+ files, split or merge PDFs, convert PDF pages to HD images, combine images into PDF, and strip EXIF metadata.
Fully offline, open source, and free forever.

Hey PH! š
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 ā what if everything just happened locally?
PrivaX processes files 100% in your browser using WebAssembly. Not "we delete your files after processing" ā literally zero network requests. Don't trust me? Open DevTools ā Network tab while using it. You'll see nothing. š
What it does:
ā¢ Image compression: PNG 4.2MB ā 890KB (79% reduction), batch 50+ files
ā¢ PDF split & merge with drag-and-drop page reorder
ā¢ PDF ā Image conversion (export pages as PNG/JPG/WebP, or combine images into PDF)
ā¢ EXIF metadata stripping
ā¢ All with no visible quality loss, works fully offline
It's completely free.
I'd love your feedback:
ā What file processing tasks do you wish could be done locally?
ā Any features you'd want to see next?
Happy to answer anything! š
