What this tool is for
Use local Real-ESRGAN inference to double image width and height; the verified model is cached after its first download and the page shows the current device limit.
How to use it
Check the input-pixel budget reported for this device, then download and cache the 2× model. Width and height are both doubled; inspect faces, lettering, and fine textures for model artefacts before using the result.
Results and next steps
Each selected source produces one result card with preview, pixel dimensions, format, and size. Download one file, selected files, or the complete ZIP.
Privacy and local processing

Before you start
Your browser must decode images into memory. Very large files, long animations, and large batches may require substantial memory. Check the preview and export details, and verify the latest official requirements before submitting identity, application, or print-ready images.
