Free Online AI Tools — 8+ Tools, No Signup

Toolkiya's AI tools are unusual in that the models actually run in your browser. Most online AI tools — image upscalers, background removers, photo enhancers — upload your image to a server, run inference there, and return the result. Toolkiya runs the same families of models locally using ONNX Runtime Web and WebGPU, so your images never leave your device.

The trade-off is honest: open-source models do not match the absolute state-of-the-art proprietary ones from companies like Topaz or Adobe. For a portrait with very fine hair against a busy background, Remove.bg's commercial model still produces cleaner edges. For most inputs, the gap is small or invisible, and the cost difference (free vs $0.20–$1 per high-res output) makes browser-native the right default for bulk work.

Models are cached after first download, so subsequent runs are fast. WebGPU acceleration (where supported) gives 5–10× speedup over CPU-only inference, comparable to a small GPU server. On a recent laptop, a 1080p image can be background-removed in under two seconds.
