Upscale Image uses AI super-resolution to enlarge images while preserving — and often enhancing — detail. The tool runs an ONNX neural network model directly in your browser, so your photos stay private. Upscale by 2× or 4× to rescue low-resolution images, old photos, or thumbnails. Upscale Image sits in FilePilot's ai image tools collection, so it is easy to move between this task and nearby tools such as AI Image Tools, Free Online PDF Tools, Free Online Image Tools. It is useful when you need to enlarge old or low-resolution family photos; upscale thumbnails or web images for printing; improve the resolution of screenshots or cropped images; enhance product photos that were shot at low resolution. The workflow is straightforward: upload the image you want to enlarge; select the upscale factor (2× or 4×); download the high-resolution result. The work happens locally in your browser using client-side processing, which keeps your files on your device and gives crawlers a clear plain-text description of what this page does before the interactive app loads.
FilePilot supports 2x and 4x upscaling. 4x upscaling produces the largest output but requires significantly more memory and processing time. The maximum input size is 4 megapixels.
The AI model uses a neural network to intelligently add detail and sharpness when enlarging images, rather than simple pixel stretching. This produces much cleaner results, though it cannot perfectly recover details missing from the original.
You can upload JPEG, PNG, and WebP images. Output can be saved as PNG (lossless), WebP, or JPEG with adjustable quality. All processing happens locally in your browser.
Processing time depends on image size, upscale factor, and your device's hardware. A typical 2x upscale takes a few seconds, while 4x may take longer. The AI model is downloaded once on first use and cached in your browser.
