Is my photo uploaded to a server?

No. All conversion happens inside your browser using the Canvas API. Your image data never leaves your device.

Why does my HEIC file fail to convert?

HEIC/HEIF decoding depends on your browser's built-in codec support. Safari on macOS/iOS has full HEIC support. Chrome and Firefox may not decode HEIC natively — try Safari if you see an error.

What quality setting should I use?

Quality 85 is a good default — it produces sharp images at roughly 60–70% of the original file size. Lower values (60–75) shrink files more but may introduce visible artifacts on photos with fine detail.

What is WebP and why use it?

WebP is a modern image format developed by Google. It provides 25–40% smaller file sizes than JPEG at comparable visual quality, and supports transparency like PNG. All major browsers support WebP.

Can I convert HEIF files too?

Yes. HEIF and HEIC are closely related — HEIF is the container format and HEIC is the codec variant used by Apple. Both are handled the same way by the converter.

Will the converted image look different?

At quality 85 or above, the difference is imperceptible to the human eye. At very low quality settings (below 60) you may notice some compression artifacts in areas with gradients or fine texture.

Summary

This tool converts HEIC and HEIF photos — the default format on modern iPhones and iPads — to WebP, a next-gen image format with excellent compression and broad browser support. The conversion happens entirely in your browser using the Canvas API, so your images are never sent to any server. WebP files are typically 25–40% smaller than JPEG at equivalent quality, making them ideal for websites, apps, and general sharing.

How it works

Click "Choose HEIC File" or drag and drop a HEIC/HEIF image onto the drop zone.
The browser decodes the image using its built-in image codec support.
A canvas element re-encodes the image as WebP at your chosen quality setting.
A preview of the converted WebP image appears alongside file size details.
Click "Download WebP" to save the converted file to your device.

Use cases

Prepare iPhone photos for use on websites that require WebP.
