LocalJPG
Convert HEIC & WebP to JPG — entirely on your device
LocalJPG converts HEIC, WebP, PNG, AVIF and BMP to JPG directly in your browser using WebAssembly — no uploads, no account, no server ever sees your photos. - MozJPEG compression with EXIF preserved - Works offline (PWA) after first visit - Batch convert + download as ZIP - Free for individual files; ZIP is $0.50 TON or $5 card
The reason I built this: I kept needing to convert iPhone HEIC photos and every tool I found uploads your files to a server. That felt wrong for personal photos vacations, family, documents.
So I built a converter that runs entirely in WebAssembly inside your browser. libheif for HEIC, @jsquash/webp for WebP, MozJPEG for compression. Your photos never leave your device not even temporarily.
A few things I'm especially happy with:
EXIF data is preserved (GPS, camera model, timestamps all intact)
Works fully offline as a PWA after the first visit
Streaming ZIP batch 100+ files without blowing up RAM
One file is always free. ZIP archive costs $0.50 that's the whole business model, no subscription, no account.
PH exclusive🎁: use code PH2026 at checkout to get the ZIP free
Would love feedback on two things:
Does it work on your device? iOS Safari has been the trickiest
Are there formats you'd want added?
Happy to answer any questions about the WASM implementation.
