How to make an image bigger

  1. Add your pictures

    Drop them above or choose them.

  2. Set it up

    Choose how many times larger, and AI or Fast. The line under them says the new size.

  3. Save the result

    Download the larger file.

What stays and what doesn't

The result is a new file. These are the things that do not come along to it:

  • camera and capture details such as make, model and date taken
  • the GPS location
  • titles, authors, keywords and comments
  • the small preview stored inside the file
  • content credentials and edit history (C2PA)
  • the embedded colour profile (colours are changed to sRGB first; very saturated colours can look slightly flatter)
  • the stored print resolution
  • other data stored in or after the picture, such as a motion-photo clip, program-specific blocks or a modification time

A JPEG or WebP saved again loses a little detail.

When it won't run

Two things stop a run before it writes anything, and each is said on the file's row. A file that cannot be read is reported as damaged, and a picture too large for this device says so, with the limit. In both cases nothing is changed and your original stays as it was. A file in a format the page does not take, such as a GIF, gets a sentence instead of a row.

  • The picture is an animation. This tool would keep only the first frame, so it leaves the file alone.
  • The picture stores its colours as CMYK. This tool can't change it without altering the colours.
  • The picture stores 16 bits per colour. This tool works in 8 bits and would flatten it, so it leaves the file alone.
  • The model could not start on this device.

Enlarging a picture: what to expect

AI adds plausible detail, so edges look sharper than with plain resampling. It can also change faces and text, so look at the result before you use it. It runs in your browser, so the picture stays on your device.

The AI model is downloaded once and takes small pictures, because it is slow on a single processor. A bigger picture is enlarged with Fast, which is plain Lanczos resampling and a light sharpen. The page says which one it will use.

Questions

Are my pictures uploaded?

No. Your pictures are processed inside your browser, on your own phone or computer, and saved straight from this page. The reading at the top of the page counts every byte sent, and it stays at 0 B.

Is the picture sent anywhere?

No. The model is downloaded to your device and runs there. Your picture is never sent anywhere.

Why does AI only take small pictures?

The model works on small blocks and is slow on a phone or laptop processor. Where the browser has WebGPU it takes bigger pictures. Fast has no limit beyond what your device can hold.
