Hey Product Hunt! 👋 I built ZeroConvert (https://getzeroconvert.com) because I got tired of uploading private PDFs, tax documents, and personal photos (like iPhone HEIC files) to cloud servers just to convert a file—only to hit a "2 files per day" paywall. How ZeroConvert works under the hood: • 100% Client-Side Privacy: Your files never touch a remote server. Everything runs inside your browser's local memory (RAM). • Audio & Video: Powered by single-threaded FFmpeg.wasm and native C++ OfflineAudioContext (decodes a 30MB audio file in ~1.5 seconds locally before MP3 encoding, plus ultra-fast stream-copy muxing for MP4). • Images (HEIC, WebP, AVIF, PNG, JPG, SVG): Instant client-side decoding via WebAssembly (libheif) and HTML5 Canvas. • PDFs & Data (PDF, XLSX, CSV, JSON, XML): Processed locally in RAM with PDF-Lib and SheetJS. It is completely free to use with zero daily limits, no watermarks, and no signups. I'd love for you to test it out with your files and let me know what formats or features I should add next!

Welcome to ZeroConvert! What file formats or batch tools should we build next?

Hey everyone!

Thanks for checking out ZeroConvert (https://getzeroconvert.com).

I built ZeroConvert so you can convert PDFs, images (HEIC, WebP, AVIF, PNG, JPG, SVG), audio/video (MP4, MP3, WAV, WebM, GIF), and spreadsheets (XLSX, CSV, JSON, XML) 100% locally inside your browser's RAM without ever uploading private files to a cloud server.

Currently supported under the hood:
