Open AI Image Upscaler 2× →1. Prepare your input
Enhance a small picture with a trained on-device model and save a PNG at twice its dimensions. Keep the original input and review the result before sharing.
2. Worked example
A 256 × 128 picture becomes a 512 × 256 PNG. Inspect letters, faces and tile boundaries before sharing.
3. Supported inputs and limits
PNG/JPEG/WebP up to 5 MB, 262,144 input pixels and 1,024 pixels per side. WebGL-capable current browser required; three-minute processing budget. 64-pixel tiles with overlap use the MIT-licensed UpscalerJS default RDN 2× model. Inferred texture may be inaccurate; not recovery of authentic missing detail. Transparency becomes white and metadata is omitted. No guaranteed quality improvement or competitor parity.
4. Recover and verify
If processing fails, read the error and reduce the input or correct its format. Choosing a new input or changing settings clears the previous result. Download the result, open it independently and check its content; a download click alone does not verify a saved file.
Try the workflow
Start with a small example and check the result before using your own data.
