Image Upscaler
What is this tool?
Image Upscaler is a client-side tool that uses an in-browser machine learning model to enlarge a photo to 2x or 4x its original resolution. Unlike simple resizing, the AI model is trained to reconstruct plausible detail as it scales the image up, rather than just stretching existing pixels.
When to use it
- Enlarging an old or low-resolution photo for printing
- Upscaling a small product image so it looks sharper on a website
- Increasing the resolution of a scanned photo or document image
- Preparing a low-res logo or graphic for a larger display
- Improving a downloaded web image that's too small for your intended use
How to use it
- 1Open the Image Upscaler and upload your photo.
- 2Choose the upscale factor — 2x or 4x.
- 3Wait while the in-browser AI model processes the image.
- 4Preview the upscaled result next to the original.
- 5Download the higher-resolution image.
Frequently asked questions
Does upscaling actually add real detail, or just stretch the image?
The AI model is trained to reconstruct plausible detail as it enlarges the image, which generally looks sharper than simple stretching, though it can't recover information the original photo never had.
How long does upscaling take?
Processing time depends on your device's hardware since the model runs locally in your browser.
What's the difference between 2x and 4x?
2x doubles the image's width and height, while 4x quadruples them; higher factors take more processing time and work best on reasonably clear source images.
Is my photo uploaded to a server for upscaling?
No, the entire process runs locally in your browser using an in-browser AI model.
Can I upscale a very blurry photo and expect it to become sharp?
Upscaling can improve resolution and add plausible detail, but it won't fully fix an already blurry or low-quality source image.
