Images Upscale

Features

• 2x and 4x upscaling with four modes. Choose 2x or 4x and a Basic, Photo, Anime or Screenshot mode; Basic, Photo and Screenshot use RealESRGAN_x4plus and Anime mode uses the anime-specific RealESRGAN_x4plus_anime_6B model. Official source 1 ↗ · Official source 2 ↗
• Batch uploads. Drop several files at once or a ZIP (up to 25 MB per file), and download a selection of signed-in results as one ZIP. Official source 1 ↗ · Official source 2 ↗
• Exact 4K export. The 4K page lets you preview the expected output and export exactly 3840×2160 or 2160×3840, either cropping the centre to fill the frame or adding borders to keep the whole image. Official source 1 ↗
• Background removal and unblur. Background removal (BiRefNet v2) produces transparent PNGs, and an unblur tool uses ByteDance's SeedVR2 restoration model at the original size; each costs 1 credit. Official source 1 ↗ · Official source 2 ↗
• Alt text, image to prompt and image to text. Gemini 3.1 Flash-Lite via OpenRouter writes alt text, titles, descriptions and keywords, a prompt for recreating the image, or extracts and translates the text in a picture, for 1 credit each. Official source 1 ↗ · Official source 2 ↗
• Workspace history. Guest results are kept for 7 days; signed-in results stay in your workspace until you delete them individually or in bulk. Official source 1 ↗

• Input size ceiling. Large images are scaled down before processing (about 6 megapixels at 2x and 2.25 at 4x in Basic, Photo and Screenshot modes), so 4x output is capped by that processed size. Official source 1 ↗
• Upscaling invents detail. Results can contain mistakes or invented detail, especially for blurry or damaged images, and no scale undoes motion blur or restores detail that was never captured. Official source 1 ↗ · Official source 2 ↗
