Frequently asked questions
What does the Image Upscaler do?
It uses AI to enlarge your photo to 2x or 4x its original size while enhancing sharpness and detail, giving you a high-resolution PNG — perfect for prints, thumbnails, product photos and old low-quality pictures.
How do I upscale a photo?
Drag and drop a photo (or click to browse), choose 2x or 4x, then click Enhance Image. Compare the result with the before/after slider and download the sharper PNG. No sign-up or installation is needed.
Is the Image Upscaler really 100% free?
Yes — completely free, forever. No sign-up, no watermark, no download limits and no hidden paid version. Every tool on SEO Tools is free.
Is my photo private when I use the Image Upscaler?
Yes. The AI runs entirely in your browser, so your photo never leaves your device. Nothing is uploaded, stored or shared.
Why does the first enhancement take longer?
The first time you use the tool, your browser downloads the AI model once (a few megabytes). After that it is cached and every enhancement is faster.
