HEIC to JPG/PNG Converter

1. Drag and drop a HEIC/HEIF file or click to select one.
2. Choose the output format (JPG or PNG).
3. Click "Convert" to decode and re-encode the image.
4. Preview the result and compare file sizes.
5. Click "Download" to save the converted image.

What is HEIC Format?

HEIC (High Efficiency Image Container) is an image format based on the HEIF standard that uses HEVC (H.265) compression. Apple adopted HEIC as the default photo format starting with iOS 11 because it produces files roughly 30 to 50 percent smaller than equivalent JPEGs while maintaining the same visual quality. HEIC also supports features that JPEG lacks, including transparency, depth maps, image sequences (live photos), and 16-bit color depth. Despite these advantages, HEIC compatibility remains limited across many platforms, websites, and applications.

How the Conversion Works

This tool uses a WebAssembly-based HEIC decoder that runs entirely in your browser. The decoder reads the HEVC-compressed image data from the HEIC container and decodes it into raw pixel data. That pixel data is then re-encoded into your chosen output format (JPG or PNG) using the browser's Canvas API. The result is a standard image file that works everywhere. Since all processing happens client-side, your photos never leave your device, making this safe for personal and sensitive images.

Common Use Cases

• Converting iPhone photos for upload to websites that do not accept HEIC
• Preparing photos for email attachments in a universally compatible format
• Converting HEIC files for use in image editors that lack HEIC support
• Batch converting photos after transferring them from an Apple device
• Creating PNG versions to preserve transparency from HEIC originals

JPG vs PNG: Which Output to Choose

Choose JPG when converting photographs and you want the smallest possible file size. JPG uses lossy compression, which discards subtle visual details that are hard to notice, producing files that are significantly smaller than PNG. At quality settings of 90% or higher, the difference from the original is virtually imperceptible. Choose PNG when you need lossless quality or when the original HEIC image contains transparency (such as portrait mode cutouts). PNG preserves every pixel exactly but produces larger files. For most photo conversion scenarios, JPG at high quality is the practical choice.
