Set the longest side in pixels, drop your images and download them at that size, with the proportions kept. Photos smaller than the target are never enlarged. It all runs in your browser, so nothing is uploaded and there is no limit on the number of files.

Pixels and print size
Print size is pixels divided by the print resolution. At 300 dpi, the usual standard for photo prints, 3000 px give 10 inches (25.4 cm) and 2048 px give about 6.8 inches (17.3 cm). If a photo is going to a print lab, resize only as far as the print needs, or send the original.
Good to know
The resized file does not keep camera data or GPS location, and transparent areas become white in JPG. Choose PNG or WebP to keep transparency.
Galerly galleries serve every photo at the right size for each screen, so you upload once at full resolution.
See client galleriesFrequently asked questions
Does resizing reduce quality?
Fewer pixels means less detail if you zoom in, but at the size the image is shown it looks sharp. The tool scales in steps for a cleaner result than a single jump.
Can I make a small image bigger?
No. Enlarging cannot add detail that was never captured, so images smaller than the target keep their size.
Are my images uploaded?
No. Resizing runs in your browser and the files stay on your device.
