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.

Convert PNG to WebP

Convert PNG images to modern WebP for much smaller files while keeping transparency. Great for faster websites. All conversion happens locally — no uploads.

Privacy-first: every image is processed locally in your browser. Nothing is uploaded, stored or transmitted to any server.

Why WebP shrinks PNGs so dramatically

PNG dates from 1996 and compresses losslessly, which is why screenshots and graphics saved as PNG are often surprisingly heavy. WebP uses modern prediction-based compression and typically cuts PNG file sizes by 60–80% at visually identical quality — and unlike JPG, it keeps alpha transparency, so logos and UI assets survive the conversion intact.

The web-performance case

Images are usually the heaviest thing on a page, and page speed feeds directly into Core Web Vitals and search rankings. Swapping PNGs for WebP is one of the highest-leverage one-off optimizations a site can make. Every browser has supported WebP since 2020, so there is no compatibility penalty left to worry about.

Batch-convert locally

Drop an entire assets folder here and it is re-encoded to WebP by your own browser — no upload queue, no per-file limits, no watermarks. Transparent areas stay transparent, and you can download everything as a ZIP when it finishes.
