Try it on your own photos.
Ten full-resolution exports. Unlimited previews. No account. Open the disk image and drag MacnifyIt to Applications; the Finder menu switches on from the app’s first-run screen. Your first successful export uses one of ten; previews, failed and stopped exports never count.

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×, 8×, or a target long edge in pixels. 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 or TIFF. 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 exports land next to the originals as name_4x.png, with a progress window you can stop at any time. No app window needed.
