PixelBoost AI
Free in-browser AI image enhancer and upscaler
About PixelBoost AI
PixelBoost AI is a free online tool for sharpening, denoising and upscaling low-quality photos. It is aimed at photographers, online sellers and anyone with old phone snaps or scanned prints that look soft, grainy or blurry.
Users upload a PNG, JPG or WebP file of up to 24 MB, pick an intensity (Subtle, Balanced or Strong) and choose between an AI mode, which runs a Real-ESRGAN neural network, and a faster mode that finishes in about a second. Results can be saved as JPG, PNG or WebP, and small images are upscaled to add resolution.
What sets it apart is that processing happens on the user's own device in the browser, so photos are never sent to a server or stored. The site states that it needs no account or credit card, adds no watermark and has no usage limit. It also links to related tools for background removal, image-to-text, resizing and cropping.
