HEIC to WebP Converter
WebP gives you JPG-like or better compression with modern browser support and optional transparency, making it a great fit for websites, product photos, and anywhere page speed matters. This tool converts your HEIC photos to WebP entirely on your device — no server upload involved.
Your photos never leave your device. Open DevTools → Network and convert a photo — you’ll see zero uploads. Learn how to verify this.
When to use HEIC to WebP
- You are publishing images to a website and want smaller files for faster page loads
- You want better quality-per-byte than JPG at the same visual quality
- You need optional transparency alongside good compression
- Your CMS or image pipeline accepts WebP but rejects HEIC uploads
How it works
- 1
Drop your HEIC photos
Drag and drop .heic files, or click to select them from your device.
- 2
Automatic local conversion
Your browser decodes the HEIC and encodes WebP locally, using WebAssembly only where it has no WebP encoder of its own — nothing is uploaded.

Download WebPs
Download files individually or as a single ZIP for the whole batch.

Frequently asked questions
Why convert HEIC to WebP instead of JPG?
WebP typically produces smaller files than JPG at the same visual quality, which helps web pages load faster. If you need maximum compatibility with older software, JPG is still the safer default.
Does every browser support WebP?
Yes — Chrome, Firefox, Safari, and Edge have all supported WebP for several years, so it is safe to use on the web today.
Can I control the WebP quality?
Yes, use the quality slider (default 90) before converting. Lower values produce smaller files at the cost of some visual detail.
Is my photo uploaded anywhere during conversion?
No. Decoding and encoding both happen locally in your browser. Check DevTools → Network during a conversion and you will see no upload requests.
Can I batch convert many HEIC files to WebP at once?
Yes. A folder drop reads up to 10,000 files, and how large a batch can run depends on your device’s memory. Download results individually or as one ZIP file.
