AI-Style Image Upscaler
Upscale images 2×, 3×, or 4× using multi-step high-quality resampling with optional sharpening — all directly in your browser, no uploads needed.
Upload Source Image
Upload
Drop any PNG, JPEG, or WEBP image up to 20 MB.
Configure
Pick scale factor (2×–4×), sharpening mode, and output format.
Download
Save your high-resolution upscaled image instantly.
100% Client-Side Privacy
Your images never leave your device. All upscaling happens directly in your browser using the HTML Canvas API.
Multi-Step Upscaling
Instead of a single stretch, we upscale in incremental steps to minimize aliasing and preserve more detail.
Sharpening Filter
Apply an unsharp mask post-upscale to restore edge clarity, perfect for low-res logos, text, and line art.
Format & Quality Control
Export as PNG (lossless), JPEG, or WEBP with adjustable quality from 60–100% to balance file size and sharpness.
Note on Quality: This tool uses high-quality canvas resampling with optional sharpening — the same technique used by professional image editors like Photoshop's "Bicubic Smoother". Results are excellent for illustrations, UI assets, and moderate photo enlargements. For extreme AI super-resolution (e.g., 8× low-quality photos), a dedicated AI model would be needed.
