## Overview

This PNG viewer renders raster images locally in your browser. It handles the most common web formats — PNG, BMP, AVIF, ICO and JXL — so you can inspect a screenshot, a transparent logo or an icon without installing anything. Pick a sample or choose your own image file to preview it instantly.

## When to use

- You received a PNG, AVIF or HEIC image and want to view it without special software.
- You need to check a transparent PNG logo or icon against different backgrounds.
- You want a quick preview of a modern format (AVIF, HEIC, JXL) your default app will not open.

## How it works

- Select a built-in sample or choose your own image file from your device.
- The viewer decodes the image entirely in your browser — nothing is uploaded.
- Inspect the image at full resolution, then switch samples or load another file any time.

## Use cases

- Previewing PNG screenshots and transparent logos.
- Opening AVIF, HEIC and JXL images that older viewers cannot decode.
- Quickly checking icon (.ico) files for favicons and app assets.

## Frequently asked questions

### Which image formats does this viewer support?

PNG, BMP, AVIF, ICO, HEIC, HEIF and JXL. All decoding happens in your browser using the platform's native image support.

### Are my images uploaded to a server?

No. Files opened from your device stay on your device. Only the public sample images are served from the server.

### Can it open very large PNG files?

Yes. The browser decodes the image locally, so the limit is your device's memory rather than an upload cap.
