OnyxPDF
50 PDF tools that never upload your files
Every 'free PDF tools' site uploads your file to their server — your contracts, bank statements and ID scans sit on a stranger's computer for a retention period you can't verify. OnyxPDF removes the server: 50 PDF and image tools run 100% in your browser via WebAssembly — merge, split, compress, convert, OCR in 7 languages, true redaction, signing, and AES-256 encryption, all on your device. No upload. No account. No cost. Test it in airplane mode — every tool still works.

Hi Product Hunt — I'm Muhammad Mohsin, a solo developer from Pakistan building Onyx AI Labs. I built OnyxPDF after a simple realisation: the documents people most need to process — contracts, bank statements, scanned IDs, signed forms — are exactly the ones they should least be uploading to a random server. Upload-based tools made sense when browsers were weak. With WebAssembly, they're not weak anymore. Your laptop is already a capable PDF machine; the upload is a habit, not a necessity. So I built the toolset I wanted to exist: 50 PDF and image tools, all running locally in the browser. Files never upload because there is no server to upload to. That includes the jobs that felt impossible client-side a few years ago — real AES-256 encryption, OCR in 7 languages, and background removal with a proper segmentation model running on-device. Don't take my word for the privacy claim — please test it. Open the site, go into airplane mode, and process a file. Or watch your browser's network tab while a document converts. That's the demo. I'd genuinely love feedback: which tool is missing, which one misbehaves on your files, what would make you switch from your current PDF site? I'll be here answering everything myself.
