Privacy: images are processed locally in your browser and never uploaded. Simply download the converted file when it is ready.
Three quick steps
- Choose an output format
JPG is the default. Switch to PNG when you need a lossless file. - Select your HEIC files
Drag & drop or use the file picker to load photos and screenshots straight from your camera roll. - Download instantly
Save the result and continue working. Blob URLs are revoked immediately so nothing lingers in memory.
Typical conversion time: Safari < 1s / Chromium 2–4s / Wasm fallback up to 40s on first load.
Why creative teams pick HEIC Savvy
Privacy first
Everything runs in the browser and once the conversion finishes the in-memory data is discarded automatically.
Hybrid performance
We fall back in order: Safari native decoders, Chromium WebCodecs, then libheif Wasm so you always hit the fastest available route.
Popular workflows
- Design & marketing: convert HEIC proofs to JPG before sharing with clients (files are normalized to sRGB for consistent color).
- IT help desks: turn employee screenshots into PNG in seconds before filing tickets or documenting fixes.
Latest from the blog
We publish updates on HEIC workflows and browser performance on the HEIC Savvy blog (Japanese).
