Make small images sharp and big.

Yes — the upscaler on this page runs entirely in your browser: no signup, no watermark, no card, and no limit on how many images you run, because it never touches our servers at all. If you want the Studio's full generative AI super-resolution model instead, that's a separate paid tool (see below) — but the free one on this page is the real thing, not a limited trial.

It uses Lanczos resampling plus an edge-preserving sharpening pass to enlarge your image 2x or 4x, reconstructing crisp edges and recovering texture as it goes — the same kind of reconstruction filter used in professional photo software, running client-side in your tab. It is a real resampling algorithm, not a neural network, so it works instantly with no upload and no account.

It noticeably sharpens soft, small, or compressed images by reconstructing edges and detail as it enlarges. Results are best when there is some real detail to work from — resampling recovers what is already there rather than inventing a brand-new photo. For the toughest sources, the Studio's AI super-resolution model can add plausible detail beyond that limit.

The free tool on this page is a resampling algorithm (Lanczos + sharpening) that runs in your browser — fast, private, and genuinely free with no signup. The Studio's upscaler is an actual AI model that can reconstruct detail generatively, useful on very degraded sources. It is one of 100+ models on a paid plan, with the exact credit cost shown before each run.

Yes — the tool on this page. Upload an image, pick 2x or 4x, and download the result with no account, no email, and nothing uploaded to a server. Signup is only needed for the Studio's AI models (image generation, background removal, video, and the AI super-resolution upscaler), which start with a one-time 3 free credits, no card.

Yes. Pick 2x or 4x on the free tool above to enlarge a smaller photo toward 4K resolution, with edges and texture reconstructed as it goes. Start from the largest source you have for the cleanest result — very large sources get resized first to keep processing fast, and the page tells you when that happens.

Plain resizing stretches pixels and softens the image. This upscaler reconstructs detail as it enlarges — sharpening edges and recovering texture — so the result holds up at larger sizes instead of looking blurry, whether you use the free browser tool or the Studio's AI model.

The free browser tool on this page never adds a watermark, on any use — it is not tied to an account. If you use the Studio's AI upscaler on the free credit tier, downloads carry a small watermark; paid plans (Standard $10, Pro $15, ProPlus $30, Ultimate $50 per 30 days) remove it and add a commercial-use license.

2x doubles each dimension (a 1000px image becomes 2000px); 4x quadruples it (1000px becomes 4000px). Pick 2x for a modest cleanup and 4x for print or large displays — both run free, right on this page.

Generate images, edit photos with a prompt, remove backgrounds, make logos, turn stills into video, add AI voiceover, and caption clips, plus the AI super-resolution upscaler — 100+ models on one subscription, with the cost shown before each generation.
