HEIC Converter

HEIC (a HEIF file compressed with HEVC) is the default photo format on iPhones and many Android phones. It saves space, but Windows apps, older software and many upload forms refuse it. This converter turns HEIC and HEIF photos into JPG, PNG or WebP right in your browser, handles whole batches and burst files, and shows what is inside each HEIF container. Your photos are not uploaded.

How to use this tool

1. Choose one or more .heic or .heif files.
2. Pick the output: JPG for compatibility, PNG for lossless editing, or WebP for small web images. Set the quality (92% looks identical to the original).
3. Optionally cap the long side for email or social media, and tick “every image” to unpack bursts and multi-image files.
4. Download the converted photos one by one or as a ZIP, and check the HEIF details table.

Formula

Long side limit L: scale = L ÷ max(width, height), applied only when the photo is larger than L

Safari 17 and later decode HEIC natively and are used first. Other browsers load the libheif decoder compiled to WebAssembly (about 1.5 MB, once) and decode each file in a fresh copy of it, so a damaged photo cannot stall the next one; the pixels are then encoded in the chosen format. Transparency in a HEIF is kept in PNG and WebP (JPG gets a white background), and the file’s full- or limited-range colour setting is honoured. The brand column shows the HEIF brand from the file’s ftyp box (heic, heix, mif1…).

Example

A 4032 × 3024 px iPhone photo of 2.1 MB converted to WebP at 92% with Max 1600 px becomes 1600 × 1200 px and typically about 300–500 KB. As a full-size JPG at 92% it would usually be 3–5 MB — larger than the HEIC, because HEVC compresses better than JPEG.
