Frequently asked questions
Everything you need to know about PixThisApp.
Is PixThisApp really free?
Yes, 100% free. No subscriptions, no ads, no upselling. Because all processing runs in your browser, we have zero server costs, and it is built to stay that way.
Where are my files stored?
Nowhere. Your files are processed entirely inside your browser and are never uploaded to any server. When you close the tab, your data is gone. We have zero access to your files, by design.
What browsers are supported?
PixThisApp works on Chrome, Edge, Firefox, Safari, and Opera. Every tool runs on WebAssembly, which all five support, so there is no fastest browser and no second-class fallback: the same code runs everywhere. Mobile browsers on iOS and Android are supported, though the AI tools are slower on older phones because WebAssembly runs on the CPU.
How does the AI work without a server?
We use WebAssembly (WASM) and ONNX Runtime to run AI models directly in your browser. The models download once and are cached locally. After that, AI features like background removal and OCR run on your device's CPU. We do not use your GPU: the WebGPU path is faster on paper, but it caused crashes in testing, so we chose the slower option that always works. Note that Upscale Image is not AI. It uses high-quality bicubic resampling, because the neural upscaler we tried ran out of memory on real devices.
Is there a file size limit?
There's no hard limit, but performance depends on your device. Most tools handle files up to 50MB comfortably. Very large files may be slower on older or low-memory devices.
Do you use cookies or track users?
No individual-level tracking, no marketing cookies, no third-party trackers. We use Cloudflare Web Analytics, which measures aggregate page traffic only. It is cookieless, doesn't fingerprint visitors, and is GDPR/CCPA compliant. We see how many people visit which page; we never see who you are.
Does it work offline?
PixThisApp needs an internet connection to load the website, the code each tool uses, and (for the AI tools) their model the first time you use them. Your files are never uploaded at any point. Once a tool has finished downloading everything it needs, the processing itself runs on your device. We do not offer full offline support today: that needs a service worker, which we have not built.
Who built this?
