How to convert HEIF to WebP
Drag and drop your HEIF files into the upload zone, or click to browse and select them from your device.
Click Convert to WebP. The conversion runs in your browser when supported, with secure server fallback if needed.
Download each converted WebP file individually, or use Download all after multiple files finish.
HEIF and WebP - what's the difference?
WebP: Choose WebP when the output is going to a web context and you want a modern format with good compression. JPG: Choose JPG instead when maximum compatibility across all platforms and older software is the priority.
Why People Convert HEIF to WebP
Convert HEIF files to WebP online for free. WebP is a modern, widely supported format that works in all major browsers and many platforms — making it a practical output for HEIF photos that need to go online.
HEIF photos from Apple devices are not widely compatible outside Apple's ecosystem. WebP is broadly supported in web browsers and many platforms, and it produces smaller files than PNG while maintaining good visual quality. Converting HEIF to WebP is practical when the photos are going to a web context — a website, CMS, or web app.
WebP strikes a balance between the efficiency of HEIF and the broad compatibility of older formats like JPG and PNG, making it a sensible delivery format for Apple device photos used in web projects.
Common situations where this helps
HEIF photos from an iPhone or Mac need to be published on a website or uploaded to a CMS that supports WebP.
Apple device photos need a web-optimised version with smaller file sizes than PNG for use in a web project.
A web developer needs to convert HEIF assets to WebP as part of an image processing pipeline.
HEIF images need to be uploaded to a platform that supports WebP but not HEIF.
Common problems and fixes
The HEIF file is not being processed.
HEIF decoding depends on browser support. Chrome and Edge handle HEIF most reliably. Try a different browser if the file is rejected.
The WebP output is not accepted by the platform.
WebP is widely supported in modern browsers but some older platforms do not accept it. Use JPG if the destination requires a more universally accepted format.
The photo colours look different in the WebP output.
HEIF can use wide colour gamut profiles. If the WebP output looks different, the colour profile may not have been fully converted. This is a known edge case with some HEIF source files.
