Question 1

How is this different from resizing an image?

Accepted Answer

Resizing stretches the pixels you already have, so a small photo made large just gets softer and blockier - there is no extra detail to show. This runs the image through an AI model that reconstructs detail at the new size: edges stay crisp, texture in fabric, hair and foliage comes back, and the result holds up when printed or viewed full screen. If your image is already big enough and you only need different dimensions, the free Image Resizer is the right tool and costs nothing.

Question 2

What do the sizes mean, and which should I pick?

Accepted Answer

Each option is a target for the finished image, measured in megapixels - width multiplied by height. Up to 4 MP is roughly 2,400 by 1,600 and is plenty for web use, social posts, and screens; it is free. Up to 8 MP matches a typical phone photo. From 16 MP upwards you are in print territory - 16 MP prints cleanly at A3, and the largest sizes are for posters, banners, and large-format work. Pick the smallest one that covers what you need, because a bigger target means a much bigger file rather than a better-looking image at normal viewing size. Whichever you pick has to be larger than the photo you are enlarging - sizes your images have already outgrown are greyed out.

Question 3

What happens if my photo is already larger than the size I picked?

Accepted Answer

It is refused, before anything is charged. The size you choose is a target the model works to, not a floor, so running a 40 MP photo at the 8 MP size would deliver it at about 8 MP - smaller than you started with, at the price of an enlargement. Sizes your photos have already outgrown are greyed out as soon as you add them, so pick one above your largest image. If you want a photo made smaller, the free Image Resizer does that and costs nothing.

Question 4

Is the smallest size really free?

Accepted Answer

Yes, up to 5 images a day, for images under 4 MP - a typical phone photo is already larger than that, so it needs one of the paid sizes. It needs an account, because the work runs on our servers and the allowance is counted per account, but no credits are held or spent and nothing appears on your credit history. Once you have used the day's allowance you can either pick a larger paid size or come back tomorrow - the allowance resets at midnight UTC.

Question 5

Is the result exactly my original photo, only bigger?

Accepted Answer

Not exactly, and it is worth knowing why. The model generates the new detail rather than recovering detail that was captured, because that detail was never in the file. On photographs the result is usually indistinguishable from a genuinely higher-resolution shot, but small text, logos, licence plates and faces at a distance can shift, because the model is inventing plausible detail rather than reading it. For anything where the exact pixels matter as evidence or as a record, treat the result as an enhanced version rather than the original.

Question 6

What do Enhance realism and Enhance details do?

Accepted Answer

Both are optional and neither changes the price. Enhance realism pushes the result towards a photographic look and helps most on AI-generated or heavily edited images, which can otherwise come out looking synthetic at a larger size. Enhance details sharpens fine texture and small features, and may raise contrast a little. Both move the result further from the original, so they are off by default - if you want the most faithful enlargement, leave them alone.

Question 7

Should I download JPEG or PNG?

Accepted Answer

JPEG unless you have a reason not to. At these sizes a PNG is lossless but enormous - a 128 MP PNG runs to several hundred megabytes, against roughly twenty for the same image as a high-quality JPEG - and the difference is not visible in a photograph. Choose PNG if the image will be edited further and re-saved several times, or if it contains flat colour and hard edges like a logo or a screenshot, where JPEG compression is easier to spot.

Question 8

What happens to my images?

Accepted Answer

Your photos are uploaded to our servers and sent to an AI model to be processed - this tool cannot run in your browser. The files are deleted four hours after you download them, or within two days if you do not. Images that fail are never charged for.
