About Image Enlarger

Lanczos-3 is the resampling filter photo editors use for resizing: it keeps edges clean and avoids the blocky look of simple scaling, and an optional light sharpen counters the softness every enlargement brings.

It is not AI upscaling. It cannot add detail that is not in the file - a 200 px photo blown up to 800 px will be smooth, not sharp.

How to use it

  1. 1Drop your JPG, PNG, WebP and GIF files into the box, paste them, or tap browse.
  2. 2Adjust the settings if the defaults are not what you need.
  3. 3Run the tool. The work happens on your own device.
  4. 4Download each result, or all of them as one ZIP.
