Open. Size. Check. Export.

How to upscale images on your Mac: open, size, check, export. The same four steps run on one photo or a whole folder.
01

Open

Drop in a photo, a selection of files, or a whole folder. JPEG, PNG, TIFF, HEIC and WebP. Or skip the window: right-click in Finder.
02

Choose the size

Pick 2×, 4× or 8×, or set the size by Longest side, Exact width, Exact height, Fit within, or Enlarge by %. See the output dimensions before you start. One approved image, every output size you need.
03

Check at 100%

Compare the source and the result at output pixel scale before exporting.
04

Export

Save as PNG, JPEG, TIFF or WebP. Keep colour profiles and supported metadata, preserve orientation, and remove GPS data if you choose.
Batches run in the background with progress you can follow and a stop button. Failed or stopped exports never count against your trial.

Right-click. Done.

Select photos in Finder, right-click, and choose MacnifyIt ▸ Enlarge 2×, 4× or 8×. The upscaled exports land next to the originals as name_4x.png, with a progress window you can stop at any time. No app window needed.
