What is PhotoEnlarger.com?
PhotoEnlarger.com offers six image enlargement algorithms—Magic Kernel Sharp, Lanczos 3, Hermite, Nearest Neighbor (without smoothing), Nearest Neighbor (with smoothing), and the AI-based ESRGAN-thick. After uploading an image, users can customize the scaling ratio and target dimensions (in pixels), and the system instantly generates multiple versions for comparison and selection. It supports input and output in JPG, PNG, and WebP formats, provides image cropping functionality, and operates entirely without installation, usage limits, or membership requirements.

Frequently asked questions
Why does the ESRGAN-thick AI algorithm respond more slowly?
ESRGAN-thick is an AI algorithm that runs more slowly when processing larger images; if your browser displays “Page Not Responding,” please wait patiently for the generation to complete.
Will my photo be uploaded to the server?
No. All enlargement operations are performed locally in your browser; your photos never leave your device—there’s no uploading and no storage.
