HEIC.dev
Convert HEIC photos to JPG, PNG, WebP, AVIF, PDF & TIFF — free, instantly, in your browser. No uploads, no account. Batch convert Apple HEIC photos in seconds.
100% Client-Side Processing
Unlike traditional online converters that upload your files to remote cloud servers, HEIC.dev leverages WebAssembly (Wasm) to process your images directly in your browser tab. This ensures your private photos never leave your device.
The HEVC Decoding Process
HEIC files use the HEVC (H.265) video compression standard for static images. Our tool uses a high-performance decoder compiled into Wasm, allowing your browser to read these complex files natively. Once decoded, the image data is re-encoded into universally compatible formats like JPG, PNG, or WebP.
Privacy by Design
By shifting the processing from the server to the client (your computer), we eliminate the primary security risk of online tools: data transit. You can even load this website and then disconnect from the internet; the conversion tools will continue to function perfectly offline because the entire "engine" is already running locally in your RAM.
Compatibility & Performance
Our tool is optimized for Google Chrome, Apple Safari, and Microsoft Edge. By utilizing your device's multi-core CPU, we can batch convert hundreds of photos faster than many server-based tools, without the bottleneck of high-speed internet uploads.
