What scale factors are available?

We offer 4 scale factors: 1.5x, 2x, 3x, and 4x. These options allow you to choose the right level of enhancement based on your needs, from moderate improvement to maximum resolution increase.

Does upscaling maintain image quality?

Yes, our advanced enhancement technology is designed to maintain image quality while increasing resolution. The enhancement algorithms work to preserve details and reduce artifacts during the upscaling process.

What file formats are supported?

We support all common image formats including JPEG, PNG, WebP, BMP, and more. The output format matches the input format to maintain compatibility.

How long does upscaling take?

Processing time depends on the image size and selected scale factor. Small images (<1MB) typically process in 1-2 minutes, while larger images may take longer. File size warnings are shown for images that may take additional time.

Can I upscale multiple images at once?

Yes, you can upload multiple images and process them together. Each image will be upscaled with the same scale factor settings, and results can be downloaded individually.

What is the maximum output resolution?

The output resolution depends on the original image size and selected scale factor. For example, a 1920×1080 image upscaled 4x becomes 7680×4320 pixels. There's no hard limit on output resolution.
