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.
