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 HEIC to PNG

Convert iPhone HEIC photos to lossless PNG, decoded entirely in your browser. Ideal when you need a pixel-perfect copy with transparency support. Nothing is uploaded.

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

When PNG beats JPG for HEIC conversion

Most people convert HEIC to JPG, but there is a case for PNG: it is lossless. A JPG re-encode throws away a little detail every time; a PNG stores the decoded pixels exactly. If the photo is headed into an editor, a print workflow, or anywhere it will be saved repeatedly, converting to PNG once avoids stacking up generation loss.

Mind the file size

The trade-off is size. HEIC is a highly compressed format, and a 12-megapixel photo that weighs 2 MB as HEIC can easily become a 20+ MB PNG, because photographic images do not compress well losslessly. Use PNG when fidelity matters more than weight; if you just need the photo to open everywhere, JPG is the smaller choice.

Decoded on your device

The HEIC decoder here runs inside your browser tab — the photo is decoded, converted and saved without touching a network. That matters for camera-roll photos, which tend to be the most personal files people own. You can convert a whole batch and nothing ever leaves your machine.
