Fix a low-resolution photo

Old phone photos, downloads, profile pictures, anything that is too small to use. PixelUp increases the resolution and rebuilds the detail at the same time.

Resolution is only half of it

Making a file bigger is easy. Making it sharp at the new size is the job. PixelUp does both in one pass.

Four to eight times the pixels, with detail

A 300-pixel photo comes back at 1K, 2K or 4K. Edges, hair and fabric are reconstructed at the new size rather than stretched, so the result reads as a real photo.

Any input size, output up to 4K

Old phone cameras

Photos from early smartphones are small, noisy and soft. The pass handles all three, so a 2010 photo can look like it was taken on a current phone.

Profile pictures and avatars

A profile photo saved from a site is often 150 to 400 pixels. It enlarges cleanly enough to reuse on a larger screen or print at small size.

Good for 200 to 800 pixel sources

How to increase a photo's resolution

Three steps, no software to install.

Upload the photo

Click the button or drop the file on this page. JPG, PNG, WEBP or HEIC up to 20 MB, straight from a phone is fine.

See the result

In about 15 seconds you see a full before/after. Drag the handle to check the exact spot you care about.

Download in HD

The download is included in the run. 2K and 4K are extra runs at 10 and 16 credits.

Questions people ask before uploading

Is this free?

Sign in with your email and get 12 free credits, enough for two runs. After that each run costs 6 credits at 1K, 10 at 2K, 16 at 4K, with the download included.

How much can resolution increase?

Up to 4K on the long edge from any input. The useful increase depends on the source: from 400 pixels, 2K looks natural and 4K starts to look painted. The preview shows you before you spend credits.

Is it the same as making the image bigger in an editor?

No. An editor stretches existing pixels and blurs between them. PixelUp reconstructs detail, so edges and texture are sharp at the new size.

Will a low-resolution face look like the person?

Yes, as long as the face is recognisable in the source. Identity, expression and age are preserved by design.

Can I fix a low-resolution logo or graphic?

Yes, with clean edges on shapes and text that are still partly readable. For a vector-style logo, a dedicated vectoriser gives cleaner results.

What sizes can I download?

1K, 2K or 4K on the long edge, as JPG or PNG. 4K is about 4096 pixels, enough for an A3 print.
