How does image upscaling work?
Upscaling increases an image's width and height in pixels. This upscaler enlarges in 2× steps with high-quality smoothing, which avoids the blocky look of simple enlargement, then applies edge enhancement so outlines and text stay crisp.
It works well for logos, screenshots, product photos and small images that need to fill a bigger space. It can't invent detail that isn't in the original, so a tiny blurry photo won't become a sharp one. Everything happens in your browser, so your images are never uploaded.

Questions
How much can I enlarge an image?
Up to 4×, with results up to 16 megapixels (for example 4000 × 4000), which is the most every browser can process reliably.
Will upscaling make a blurry photo sharp?
It will look smoother and crisper than a plain enlargement, but no upscaler can recover detail that was never captured. It works best on images that are small but already clear.
Is this an AI upscaler?
No. It uses high-quality resampling and edge enhancement in your browser, so it's instant and keeps logos and text exactly as drawn. For blurry or low-quality photos, try the AI photo enhancer, which rebuilds detail with AI.
Which format should I save as?
PNG for logos, screenshots and graphics; JPG or WebP for photos to keep file sizes down.
