Will converting HEIC to WEBP significantly reduce my file size?

Images

HEIC → WEBP

Learn about the formats: What is WEBP? What is HEIC?

Convert HEIC raster images from Apple devices into modern WEBP raster images instantly. Ideal for web developers and platform administrators who need browser-ready graphics.

HEIC is Apple’s native container format used extensively in iOS and macOS for storing high-efficiency raster images. WEBP is an advanced raster image format developed by Google specifically for high-performance web delivery, supporting superior compression algorithms. During the HEIC to WEBP conversion, the underlying pixel grid is re-encoded from HEIF container structures into container-native WEBP blocks.

Since both HEIC and WEBP are lossy raster image formats, this conversion involves transcoding between two compressed structures, meaning repeated compression steps will progressively degrade image fidelity.

Tips

Convert HEIC to WEBP right before uploading assets to your website to ensure native browser compatibility.
Expect the file size to change insignificantly because both formats utilize highly efficient modern compression algorithms.
Avoid converting the same WEBP file back to HEIC multiple times to prevent compounding compression artifacts.

Common use cases

Publishing photos shot on iPhones directly onto web blogs and e-commerce platforms that lack native HEIC support.
Optimizing website media pipelines by replacing Apple-specific image assets with universally supported web formats.
