Why HEIC Killer?

We built the tool we wanted to use. No ads, no uploads, just pure performance.

Zero Server Upload

Your files never leave your computer. We use WebAssembly to process everything locally. This guarantees 100% privacy for your sensitive documents.

Multi-Core Processing

Built for speed. We spawn a dedicated worker thread for each conversion, utilizing your CPU's multi-core capabilities for blazing fast batch processing.

Batch Conversion

Drag and drop 100+ files at once. Our smart queue system manages memory usage to ensure your browser never crashes, even with huge batches.

ProRAW Support

Handle massive 48MP ProRAW files (up to 100MB per file) from the latest iPhones with ease. We output high-fidelity JPGs or PNGs.

Metadata Preservation

Keep your EXIF data intact. Location, date taken, camera settings—everything is preserved in the converted file.

Instant ZIP Download

Don't click generic 'Download' buttons 50 times. One click gets you a neatly packaged ZIP file of all your converted images.
