AI Image Upscaler
Upscale a low-resolution image into a sharper, higher-res version using AI. Free to use, no signup required for occasional use.
What is the Image Upscaler?
The Image Upscaler is a free online tool that uses an AI super-resolution model to increase the resolution of a photo while adding back plausible fine detail, producing a noticeably sharper result than a simple resize would. Stretching a small or low-resolution image up with a basic resize just spreads the existing pixels out, resulting in a soft, blurry image; this tool instead uses a model trained specifically to reconstruct edges, textures, and detail that a naive resize can't recover, giving old photos, small product images, or compressed screenshots a cleaner, more usable result at a larger size. It's useful for restoring old or low-quality family photos, preparing a small product image for a larger print or listing, or salvaging a screenshot or scanned image that needs to look sharper at a bigger size. After upscaling, the tool shows a before/after comparison slider so you can drag between the original and upscaled version and directly see the improvement in detail and sharpness before downloading.
How to use it
Upload the low-resolution image you want to improve — JPG, PNG, or WebP are all supported. Click 'Upscale image' and the tool sends your photo through an AI super-resolution model that reconstructs detail while enlarging the image. Processing can take a little longer than a simple resize since the model is doing real reconstruction work, so allow a few seconds depending on the image size. Once complete, use the before/after slider to drag across the result and compare the original resolution against the upscaled version directly on top of each other. When you're happy with the result, click 'Download' to save the higher-resolution image to your device. For best results, start with the clearest, least-compressed version of the original image you have available, since the model works from whatever detail is present in your upload.
Frequently asked questions
How much larger does the upscaled image get?
The tool upscales your image using a fixed enlargement factor from the underlying AI model, producing a noticeably sharper and larger result than a basic resize.
Is this different from just resizing an image bigger?
Yes. A plain resize just stretches existing pixels and looks blurry; this tool uses an AI model trained to reconstruct plausible detail and edges, giving a sharper result.
Can I compare the before and after result?
Yes, a before/after slider lets you drag across the image to directly compare the original and upscaled versions before downloading.
What image formats are supported?
You can upload JPG, PNG, or WebP images, and the upscaled result is returned as a downloadable image file.
