Convert HEIC to WEBP: Free Online Guide
If you're uploading photos to a website, online store, or blog, file size directly affects how fast your pages load. WEBP, a modern format built by Google specifically for the web, typically produces noticeably smaller files than JPG or PNG at similar visual quality — making it the better target format for HEIC photos headed for the web rather than for sharing or printing.
This guide covers how to convert HEIC to WEBP for free, directly in your browser, with no upload and no sign-up.
How to convert HEIC to WEBP online for free
Heicly decodes and re-encodes your images entirely inside your browser tab — nothing is sent to a server, so there's no upload wait and nothing stored anywhere afterward.
- Open Heicly in any modern browser — desktop or mobile.
- Set the output format dropdown to WEBP.
- Drag and drop your HEIC files onto the page, or click to browse — up to 15 at once.
- Download each WEBP individually, or grab all of them together as a single zip file.
Why it's private: since conversion runs with JavaScript in your own browser, there's no upload endpoint your photos ever pass through — not even briefly. Nothing about the image reaches Heicly's servers.
Why choose WEBP for HEIC conversion?
- Smaller file sizes — WEBP typically compresses more efficiently than JPG or PNG at comparable quality, meaning faster page loads.
- Modern browser support — all current major browsers display WEBP without any plugin or fallback needed.
- Good for e-commerce and content sites — smaller images mean faster load times, which matters for SEO and user experience alike.
- Supports both lossy and lossless modes — WEBP can be tuned depending on whether file size or fidelity matters more for a given image.
One caveat: while WEBP is very well supported today, it's still slightly less universal than JPG for things like sending a photo to someone via email or messaging apps — for that use case, see our HEIC to JPG guide instead.
