A PNG that is too small is a familiar problem. The logo exists only as a 300 pixel file from an old website. The illustration was exported at screen size and is now wanted in a brochure. The cut-out product picture is fine on a phone and soft on a desktop. This page doubles the width and the height with a super-resolution model and returns a PNG, so the transparent parts of the picture are still transparent afterwards.
PNG has one advantage as a starting point. It is lossless, so the model works from clean pixels and not from the blocks and noise a JPEG would bring with it. Clean input is what these models handle best.
Images of up to one megapixel can be upscaled free, 2.25 megapixels on Pro. The model runs on our own servers, with no outside service involved. The upload is encrypted, and the picture and its result are deleted within one hour.
It suits some PNGs far better than others
The model was trained on photographs and natural images. Photographic PNGs, such as cut-out products, portraits on transparency and scanned pictures, are its home ground and gain the most. Illustrations with shading and painted artwork usually do well too, because their soft transitions resemble photographs.
Flat graphics are less predictable. A simple logo with clean curves generally comes out with smooth, sharp edges. A screenshot of an interface may show slight wobble in small text, since the model treats letters as texture. Pixel art is the clear mismatch: the model rounds off the hard squares that are the whole point of the style, so use nearest-neighbour scaling in a pixel-art editor for that.
When a vector file is the real answer
If the picture you are enlarging is a logo, stop and ask whether a vector version exists. An SVG, an EPS or an Illustrator file can be rendered at any size with perfect edges, and no model can match that. Designers nearly always have one, and brand pages on company websites often offer it for download. This site converts all three to PNG.
Upscaling is for the case where the vector is lost for good. It will make a 300 pixel logo usable at 600. It will not make it usable on a banner two metres wide.
Expect a much larger file
The output is a lossless PNG with four times the pixels. For flat graphics that is still a small file. For a photographic image it is not: a cut-out of 1000 by 1000 pixels that weighed 1.5 MB can come back at 2000 by 2000 and 6 MB.
Change the output format in the editor if that is too heavy. WebP keeps the transparency in a fraction of the size and suits anything going onto a website. If you need PNG and the picture has flat colours, run the result through the PNG compressor on this site, which reduces the palette and leaves the transparency alone.
Frequently asked questions
Is the transparent background kept?
Yes. A transparent PNG comes back transparent, at twice the size, with its soft edges intact.
Will my logo get sharper edges?
Usually smoother and cleaner than plain enlarging gives. Very thin lines and tiny lettering can come out uneven. Check the result at full size.
Can I upscale pixel art?
It will be smoothed, which defeats the style. Pixel art needs nearest-neighbour scaling at a whole multiple, and this tool does not do that.
How large can the PNG be?
One megapixel on the free plan, for example 1000 by 1000, and 2.25 megapixels on Pro, measured before upscaling.
Can I get more than twice the size?
Each pass doubles the picture. Run the result again while it is still under the limit: 500 by 500 becomes 2000 by 2000 in two passes on the free plan.
Is the upscaled PNG lossless?
The file is, in the sense that it stores the model's output exactly. The added detail itself is the model's estimate and not information from your original.
