HEIC to WebP Converter - Free Online Tool
What is a HEIC to WebP converter?
A HEIC to WebP converter transforms Apple's High Efficiency Image Format (HEIC/HEIF) into WebP, Google's modern image format designed for the web. Both formats offer excellent compression, but WebP has far broader support across browsers, websites, and platforms. This tool decodes HEIC images entirely in your browser and outputs optimized WebP files ready for web use.
How to use the HEIC to WebP converter
- Upload your HEIC file: Drag and drop or click to select a HEIC/HEIF image from your device. Files up to 10MB are supported.
- Adjust quality settings: Use the quality slider to balance file size and image clarity. WebP excels at lower quality settings while maintaining visual fidelity.
- Download your WebP: Click the download button to save the converted image instantly to your device.
Why use this HEIC to WebP tool?
- Superior web performance: WebP files are 25–35% smaller than equivalent JPGs, speeding up page loads.
- Modern browser support: All major browsers (Chrome, Firefox, Safari, Edge) support WebP natively.
- Transparency and animation: WebP supports alpha channels and animation, unlike JPG.

Common errors
File won't upload
Ensure the file extension is .heic or .heif. Some cloud services convert HEIC to JPG automatically—check that you have the original file.
WebP not opening on older system
Windows 10 (pre-2018) and older macOS versions need codec updates to view WebP. The file is fine; the system needs updating.
Quality seems lower than expected
WebP uses aggressive compression. If the result looks soft, increase the quality slider to 85–95 for photos with fine details.
Tips and proven approaches
- Quality 75–85 works well for most web photos; use 85–95 for images with text or fine details.
- WebP supports lossless compression too—useful for screenshots and graphics.
- Test WebP images on your target audience's browsers before deploying site-wide.
- For maximum compatibility with old browsers, provide JPG fallbacks alongside WebP.
