Convert HEIC to WebP
Decode iPhone HEIC photos locally and re-save them as small, modern WebP files — ideal for the web. Your photos never leave your device.
Privacy-first: every image is processed locally in your browser. Nothing is uploaded, stored or transmitted to any server.
iPhone photo to web-ready in one step
If an iPhone photo is destined for a website, converting HEIC to JPG first and WebP second re-encodes it twice and wastes quality both times. Going HEIC → WebP directly decodes the photo once and encodes straight into the web’s best-supported modern format — smaller than an equivalent JPG by around 30%.
When to choose WebP over JPG
Choose WebP when the destination is a browser: websites, blogs, web shops, anything embedded in a page. Choose JPG when the file goes to people or print — email attachments, shared folders, office documents — where older software may still balk at WebP. Either way, the bundled HEIC decoder runs in your browser and your camera roll never leaves your device.
Frequently asked questions
- Which formats are supported?
- You can convert to and from JPG, PNG, WebP, AVIF and BMP, and convert from HEIC/HEIF (iPhone photos). Browsers cannot create HEIC files, so HEIC is input-only. Output formats your browser cannot encode are detected and disabled automatically.
- Can I convert HEIC to JPG?
- Yes. Drop in a HEIC photo from an iPhone and choose JPG (or PNG/WebP). The HEIC file is decoded locally in your browser with a bundled decoder — it is never uploaded anywhere.
- Is transparency preserved?
- Yes, when converting to a format that supports an alpha channel (PNG, WebP, AVIF). For formats without transparency (JPG, BMP), you can pick a background color for transparent areas.
- Is my image uploaded?
- No. Conversion runs entirely in your browser — your images never touch a server.
- What is AVIF and should I use it?
- AVIF produces the smallest high-quality files. Encoding support varies by browser, so PixelVault enables it only when your browser can create AVIF files.
- Can I convert many images at once?
- Yes. Batch-convert a whole folder of images and export them together as a ZIP.
