PhotoEnlarger.com

PhotoEnlarger.com is a free online tool that enlarges and enhances your photos without quality loss. It runs entirely in your browser, processing images locally to ensure privacy—no uploads, no storage. The tool offers six different enlargement algorithms: Magic Kernel Sharp, Lanczos 3, Hermite, Nearest neighbor (no smoothing), Nearest neighbor (smoothing), and the AI-based Esrgan-thick. This AI algorithm (ESRGAN) provides intelligent upscaling, though it may be slower for large images. After enlargement, you can preview results and download them in JPG, PNG, or WebP format. The tool also includes a cropping feature to fine-tune your output. No registration or payment is required, and there are no usage limits, making it accessible for quick image upscaling tasks.
