Any file up to 500 MB. Drop several files and they come back as one ZIP. Many image, audio and video conversions run in your browser; anything else is uploaded and removed within the hour.
Convert WEBP raster images to Apple's HEIC format instantly using ConvertX. This tool is designed for users needing to move web graphics into the Apple ecosystem.
Both WEBP and HEIC are modern raster image formats, but they serve different environments. WEBP was created by Google primarily for web optimization, while HEIC is based on the HEIF standard and optimized for iOS and macOS devices. During the conversion from WEBP to HEIC, the pixel data is repackaged, but because both formats use lossy compression techniques, moving between them requires a transcode that changes the compression structure.
Since both WEBP and HEIC formats use lossy compression, repeated re-encoding between them will inevitably degrade image quality. Try to convert from the original master file whenever possible to minimize cumulative compression artifacts.
We built this project so anyone can convert files without paywalls, accounts, or hidden limits. Here is what that promise means in practice.
Every converter on ConvertX is free to use: no trials, no premium tiers, and no credit packs. We will never put core conversion features behind a subscription. Whether you convert one photo or a hundred files a week, the price stays zero.
Many image, audio, and video conversions run entirely in your browser. Your files never leave your device for those jobs. When server processing is required for documents or specialized formats, uploads are handled securely and removed automatically — typically within one hour.
A quick guide to strengths and trade-offs of popular formats — so you pick the right one before converting.
