NativeConvert
Convert files in your browser, nothing is uploaded
NativeConvert converts and edits files inside your browser tab with WebAssembly, so your photos, PDFs and recordings never leave your device. 160+ image, audio and video format pairs (HEIC, WebP, AVIF, MP4, MOV, MP3, FLAC) plus PDF, image, video and audio tools. Free, no account, no watermark.
Hi Product Hunt! I'm Dmitriy, and I built NativeConvert.
It started with a simple annoyance: every online converter I tried uploaded my files to its servers first, even for a quick HEIC to JPG. That felt wrong for things like scanned contracts, ID photos or voice notes.
NativeConvert does the work inside your browser tab with WebAssembly: FFmpeg.wasm for audio and video, pdf.js and pdf-lib for PDFs, Tesseract for OCR, Whisper on ONNX Runtime Web for speech to text. Your files never leave your device. You can check it yourself: open DevTools, go to the Network tab and convert a file.
What's inside: 160+ image, audio and video format pairs (HEIC, WebP, AVIF, MP4, MOV, MP3, FLAC...), PDF tools (compress, merge, split, sign, OCR, redact), image tools (background remover, AI upscaler, GIF maker) and audio/video tools (trim, compress, subtitles). Free, no account, no watermark.
Honest limits: very large videos are slower than on a server because your own CPU does the work, and there is no Word to PDF yet.
I'd love your feedback: which tool or format should I add next?
