Frequently Asked Questions
Upload a JPG, PNG, or WebP image to the Upscale Image tool. Choose 2x HD (doubles width and height) or 4x Ultra HD (quadruples both dimensions). Click "Upscale Image" and download the higher-resolution PNG.
2x doubles each dimension, producing 4x as many pixels - great for general sharpening or moderate print use. 4x quadruples each dimension (16x more pixels), pushing a 1080p image to 4320p - ideal for large-format printing or extreme crops.
OCRFire uses high-quality multi-pass bicubic interpolation via the browser's Canvas API - fast and entirely client-side. For AI-based super-resolution that can hallucinate fine details, a dedicated AI upscaling service would be needed.
Upscaling enlarges the image and smooths edges through interpolation, but it cannot reconstruct detail that wasn't in the original. Severely blurry or low-resolution originals will be larger but not meaningfully sharper.
