How We Tested Image Upscalers
We tested each upscaler with three images: a 480p photograph, a 720p screenshot with text, and a low-resolution AI-generated illustration. We upscaled to 2x and 4x and compared detail recovery, artifact introduction, and how well text remained readable.
Which Free Upscaler Should You Use?
For general photos, EditThisPic is the best free option because it intelligently adds detail during upscaling rather than just smoothing. For maximum quality with no budget constraints, Topaz Photo AI is unmatched. For anime and illustration upscaling, Bigjpg and Waifu2x handle stylized content better. Upscayl is the best choice for privacy-conscious users who want to process locally.
Step-by-Step Guide
Upload Your Low-Resolution Image
Drop your image into EditThisPic. It works with any resolution, but the AI has more to work with when starting from at least 300-500 pixels wide.
Describe the Upscaling
Type: 'upscale this image to higher resolution and enhance the details.' For specific needs: 'upscale this and sharpen the face details' or 'upscale and make the text crisp.'
Download Your Enhanced Image
Save the upscaled result. The AI-enhanced version should have visibly more detail than simple interpolation would produce.
