There is a face enhancement option that rebuilds eyes, mouths and skin, which helps a lot on old portraits. Leave it off for landscapes, documents and product photos, where it can soften detail. A rebuilt face is a plausible reconstruction, not a recovered photograph, so do not treat it as evidence of what someone looked like.

AI Image Upscaler: Enhance and Enlarge Photos

Q: Does the quality really improve?

Yes, on the kind of picture it is built for. The model was trained on millions of image pairs, so it predicts the edge, texture and lettering that a small or compressed photo lost. A soft phone photo or an old scan gains a great deal. A picture that is already large and sharp has little left to recover.

Q: Is my photo stored anywhere?

No. Your photo is sent to an AI service to be processed, because rebuilding detail needs a graphics card Bubixo does not have. The provider deletes the inputs, outputs and logs of an API request within an hour, and the copy on the Bubixo side is deleted after 24 hours. Your browser never contacts the provider directly.

Q: Is it free, and is there a daily limit?

It is free with no account. Because every image costs real money to process, there is a fair-use limit of five images per person per day, and a 4x job counts as two.

Q: How large an image can I upload?

Up to 12 MB. For 2x the picture can be about 1920x1080; for 4x it must be about 1280x720 or smaller. A photo that is too big to enlarge is not rejected: the no-enlarging mode repairs the faces and returns the photo at its original size, up to about 16 megapixels.

Make a Small Photo Sharp Again

Upload a blurry or low resolution picture and get it back enlarged two or four times, with the detail rebuilt rather than stretched. Free, no account, and you compare before and after before downloading.

Rebuilt Detail, Not Stretched Pixels

It invents the detail back

Ordinary enlarging spreads the pixels you already have, so you get a bigger blur. This model was trained on millions of sharp and degraded image pairs, so it predicts what an edge or a piece of lettering should look like and draws it in.

Two sizes

2× suits most photos and takes pictures up to about 1920 × 1080. 4× is for genuinely tiny images and takes up to about 1280 × 720. A photo too big to enlarge can still have its faces repaired at its original size, up to about 16 megapixels.

Faces, if you want

A separate model can rebuild eyes, mouths and skin. It transforms old portraits but softens landscapes and product shots, so it is a checkbox rather than always on.

Three Steps

Choose a photo. Drop a JPG, PNG or WebP onto the page. Small and soft pictures gain the most.

Pick the size and whether to repair faces. The page shows the exact resolution you will get before anything is sent. If the photo is already too big to enlarge, it offers to repair the faces instead and keep the size unchanged.

Compare, then download. Drag the handle across the result to see what changed before you save it.

Where Your Photo Actually Goes

This tool works differently from most tools on Bubixo, and it is worth being plain about it. Rebuilding detail needs a graphics card our server does not have, so your photo is sent to an AI service that runs the Real-ESRGAN model and returns the enlarged image. Other Bubixo tools work in your browser or on our own machine; this one does not.

Your photo is not stored. The AI provider deletes the inputs, outputs and logs of an API request within an hour by default, and the copy on the Bubixo side is deleted after 24 hours.

Your browser never talks to the provider directly. The request goes through Bubixo, so no key, account or tracking from the provider reaches you.

No account, no email address and no payment details are asked for at any point.

Because a third party does the processing, please do not upload identity documents, medical images or anything else you would not want processed outside Bubixo.

What It Can and Cannot Do

Super-resolution is a prediction, not a recovery. It gives you the most likely sharp version of what it sees, which is exactly right for a soft holiday photo. It cannot read a number plate that was never captured, and a rebuilt face is a plausible face rather than a recovered one, so it is never evidence.

Heavy JPEG artefacts, motion blur and very dark images are the hardest cases. If the first attempt disappoints you, try the other scale or turn face enhancement off.
