HEIC → JPG Converter

Does my HEIC file leave my device?

No. All conversion happens locally in your browser. Your HEIC files, decoded pixels, output JPGs, and filenames never leave your device. No uploads, no cloud processing.

What is HEIC and why does my iPhone use it?

HEIC (High Efficiency Image Container) is Apple's format for HEIF images, using HEVC compression. It's the default photo format since iOS 11, producing smaller files at higher quality than JPEG.

Can I convert multiple HEIC files at once?

Yes. Drag a folder or select multiple files to batch-convert them all. Each file is processed individually and you can download the results as a single ZIP archive.

Will I lose quality converting HEIC to JPG?

HEIC uses more efficient compression than JPEG, so the same visual quality can be stored in a smaller file. Converting to JPG at high quality (85–95) preserves most detail, but JPEG introduces its own compression artifacts. Use quality 95+ for lossless-looking output.

What is the difference between HEIC and HEIF?

HEIF is the container format specification; HEIC is Apple's specific implementation of HEIF using HEVC video compression. For practical purposes they are the same when converting photos.

Can I convert Live Photos or burst sequences?

Yes. In Mode step, choose 'One JPG per frame' to extract every frame from a burst or sequence HEIC, or 'Contact sheet' to produce a single grid image. Sequence detection is automatic.

Does this work offline after the page loads?

Yes. Once the page has loaded and the decoder is ready, conversion works entirely offline. No network requests are made during conversion.

Why does conversion fail in Firefox?

Firefox does not natively support HEIC decoding. The tool uses your browser's built-in HEIC decoder as primary path, and falls back to a WASM decoder. If both fail, try Safari or Chrome on macOS/iOS which have native HEIC support.
