Does Sora's Pixel Converter Upload My Images to a Server?

No. Sora's Pixel Converter processes everything locally in your browser. According to the site, images are never uploaded to any server and no data is stored. The conversion runs on your own device using palette color approximation — no AI service, no remote processing. This makes it suitable for images you'd rather not hand to an online service, such as personal photos, unreleased design work, or client material.

How the local processing works

The tool does not send your file anywhere for analysis. Instead, it performs the conversion in the browser tab:

1. You load an image by dragging and dropping it onto the window, clicking to select a file, or pasting from the clipboard with Ctrl+V / Cmd+V.
2. The browser downsamples the image to the pixel size you choose (2–5 px).
3. Each pixel is mapped to the nearest color in your selected palette (18 options, including Game Boy, NES, CGA, C64, and PICO-8), optionally with Floyd-Steinberg dithering.
4. You fine-tune with dithering, line erosion, and brightness/contrast/saturation controls, then optionally edit pixels, add a dialog overlay, or stack effects.
5. You export a PNG or a video (MP4/WebM).

Every step above happens on your machine. The site explicitly states that no AI is used and that all processing runs entirely in the browser.

What this means in practice

The offline capability is a useful confirmation of the local-processing claim: once the PWA is loaded, it can run without a network connection, which would not be possible if conversion depended on a remote server.

When local processing matters — and when it doesn't

Local-only processing is the main reason to pick this tool over a cloud-based converter if your image is sensitive. For example, if you need to pixelate a photo of a document, a personal portrait, or an unreleased product mockup, keeping the file in the browser avoids the question of what happens to it after upload.

If your image is already public or generic — a stock photo, a game screenshot, a logo you plan to publish — the privacy difference is less important, and you can choose a converter based on output quality and features instead.

Limits to keep in mind

• "No upload" is a claim about this tool's behavior, not a guarantee about your browser, extensions, or clipboard. If you paste from the clipboard, the image passes through your operating system's clipboard, which is outside the tool's control.
• The site does not describe account systems or cloud saving, so there is no server-side project storage to rely on. Save your PNG or video export before closing the tab.
• PWA offline mode requires an initial load while online; after that, the cached app can run offline.

For a quick privacy check on any browser-based converter, open your browser's developer tools, switch to the Network tab, load an image, and watch for outgoing requests during conversion. With a truly local tool, you should see no request carrying your image data.
