How to upscale image online?
Here are the 3 easy steps on how to upscale an image:
- Upload the image you want to upscale
- Set up processing options: 2X, 4X, 6X, 8X.
- Wait for 10-40 seconds while the upscale process goes
- Preview the result and download the image.
Upscale Image up to 16K
You can increase the size of an image up to 16K, depending on its initial size. If the image size is less than 2000 pixels, it will be multiplied by the number of times described below.
If an image is 1000×1000 and you use 4x, the final image will be 4000×4000. However, images larger than 2000 pixels will first be reduced to 2000 pixels, and then upscale using the following method:
- Upscale 2Ñ… image resolution up to 4K (4000*4000 px)
- Upscale 4Ñ… image resolution up to 8K (8000*8000 px)
- Upscale 6Ñ… image resolution up to 12K (12000*12000 px)
- Upscale 8Ñ… image resolution up to 16K (16000*16000 px)
How does image upscaling work
Upscaling a picture is a way to increase photo resolution by generating new pixel data that wasn’t originally present in the file. Instead of relying on standard resizing — which simply stretches the image and blurs the pixels into a soft gradient — the system analyses the photo to understand its shapes and textures. It studies edges, contrast, repeated patterns, and other visual cues to determine what the image is composed of.
Once the model has a general idea of the scene, it moves to reconstruction. Our tool uses a GAN-based approach trained on a large set of real photographs. Because the model has seen many examples of natural detail, it can form a reasonable expectation of what finer structure should appear when the image is enlarged.
During processing, the upscaler fills the areas where information is missing and generates pixels that match the style of the original photo. This method helps restore small details and improves clarity without changing the character of the image.
Tips for Successful Upscaling up to 4,8 and 16K
To ensure your 8K upscaling journey is as effective as it is thrilling, consider these expert tips:
Start with the Best Quality You Have: The better the original, the better the outcome. Even though our technology works wonders, beginning with the highest quality image available to you will produce superior results.
Understand the Limits: Upscaling can achieve remarkable improvements, but it’s not a miracle worker. Our AI Upscale Image tool can provide a maximum resolution of 8K.
Use the Right Format: For the best results, use images in formats that retain quality, such as PNG or TIFF. These formats are less likely to introduce artifacts during the upscaling process compared to more compressed options like JPEG.
