Upscale Image
Enlarge images with standard resampling or browser-local AI super-resolution — free, private, no upload required. Batch process up to 20 files at once, right in your browser.
100% Private
Every file is decoded, upscaled, and packaged entirely on your device. Nothing is uploaded, stored, or transmitted to any server — including the AI model, which runs locally in your browser.
What it does
Enlarge images by an arbitrary factor using standard resampling, or use browser-local AI super-resolution for sharper detail. Preserves the original format when possible. Batch process up to 20 files.
Limitations
AI mode requires a one-time 64 MB model download and a capable device. Images above 12 MP or 4096 px longest side are not supported in AI mode. HEIC/HEIF inputs fall back to PNG or JPEG output.
