Batch HEIC Converter — Convert Multiple HEIC Files at Once

iPhone photos piling up in HEIC format? Convert them all at once — free, private, and directly in your browser.

Why Batch Convert HEIC?

HEIC is great for saving storage space on iPhones, but it causes problems when you need to share photos, upload to websites, or open them on older devices. Converting one HEIC at a time is tedious. Batch conversion saves you hours.

How to Batch Convert HEIC to JPG or PNG

1
Go to Formly and select multiple HEIC files — drag them all at once or use the file picker with multi-select.
2
Choose your output format: JPG for smallest files, PNG for lossless quality, WebP for web optimization.
3
Set the quality slider — 85% is recommended for most photos.
4
Click Convert All. Each file is processed in sequence with a progress indicator.
5
Download all converted files as a single ZIP — one click, everything saved.

Why This Works Without Any Upload

Formly uses WebAssembly to decode HEIC files directly in your browser. The HEIC data never leaves your device — no server, no upload, no privacy risk. This is also why there's no file size limit: since nothing is uploaded, you can process files of any size your device can handle.
