About Pixauro

What is Pixauro?

Pixauro is a collection of free, browser-based image tools — convert, compress, and process images without installing software or creating an account. Every tool runs entirely on your device; nothing is uploaded to any server.

The project is built as an independent tool site focused on doing one category of tasks extremely well: working with images. There is no paid tier, no login wall, and no file size limit imposed by a server — your hardware is the only constraint.

How conversion works

When you drop a file into any Pixauro tool, processing happens in three steps, all inside your browser tab:

1. Decode — the browser reads the source file using the built-in Canvas API (createImageBitmap) or, for HEIC/HEIF files, a WebAssembly decoder that runs locally in the tab.
2. Render — the decoded pixels are drawn onto an offscreen HTML Canvas element at full resolution.
3. Encode — the canvas is serialised to the target format (PNG, JPEG, WebP) via canvas.toBlob() at the quality level you choose. The result is a Blob in memory; the download link points directly to it without any network round-trip.

The WASM decoder for HEIC is loaded on demand — only when you actually open a HEIC tool — so it does not affect page load time for any other converter.

Why you can trust it

• —No uploads. Your files are processed in JavaScript memory inside the browser tab. They are never sent to Pixauro's servers because Pixauro has no file-processing servers. You can verify this by opening your browser's Network tab and watching: no outbound requests for your image data.
• —Works offline. After the page loads, you can disconnect from the internet and every tool will continue to work. The only network dependency is the initial page load and the WASM bundle for HEIC.
• —No account, no tracking of your files. Pixauro does not know what files you process, how many, or their contents.
• —Static hosting. The site is a pre-rendered static bundle served from Cloudflare's CDN. There is no application server that could intercept traffic.
