Is transparency preserved?

WebP and HEIC are both modern, efficient formats - WebP optimised for the web, HEIC optimised for Apple's ecosystem. Converting WebP to HEIC makes sense when images downloaded from the web need to live alongside your iPhone photo library: Apple Photos, iCloud, and macOS tools treat HEIC as a first-class citizen, and HEVC compression typically shaves a further 10–30% off the WebP's size at equivalent quality.

WebP files accumulate quickly when saving images from Chrome or Edge - Browsers save images in their original web format, which is increasingly WebP. If your downstream tools are Apple-centric (Photos, Final Cut, Pages) or you simply want one consistent format across a photo archive, converting those strays to HEIC unifies the library.

Both formats support alpha transparency, so transparent WebP graphics carry their alpha channel into the HEIC intact. Note that both encodings are lossy (unless the WebP was lossless), so this is a lossy-to-lossy conversion: at quality 85%+ the second-generation loss is invisible, but keep originals if you expect repeated re-encoding.

Reasons to convert WebP to HEIC usually come down to compatibility, file-size, or specific feature requirements. Common situations:

• An app or platform only accepts HEIC uploads.
• You need a feature unique to HEIC (e.g. transparency, vector scaling, animation, multi-page pages, etc.) that WebP doesn't provide.
• You're optimising file size — modern formats often produce smaller files than the older format you started with.
• You need a single archival format across a project so files behave consistently in the same viewer.

1. Open the WebP → HEIC tool on heic.now.
2. Drag your WebP file onto the drop zone, or click Select files. You can drop a whole folder of files at once.
3. The output is fixed to HEIC. If the format supports extra options (page size, transparency background, quality, EXIF stripping), tweak them in the right-hand panel.
4. Click Convert. The job runs on our server and finishes in a few seconds for typical photos.
5. Download the result. Files stay in storage for 24 hours and are then permanently deleted.

The entire flow is free for the first 10 jobs per day with no signup required. A free account doubles that quota; a premium plan removes the limit entirely.

• Use quality 85–90% to minimise additional quality loss when converting a lossy WebP to HEIC.
• Transparency in the WebP is preserved - HEIC supports a full alpha channel.
• Animated WebP files convert as a still image of the first frame - Animation is not carried across.
• Remember the output is Apple-ecosystem-friendly but web-hostile: browsers cannot display HEIC, so convert back to WebP or JPG before publishing online.
