Use cases
Shrinking the canvas often saves more than over-editing quality settings. Resize first for cleaner, more predictable output.
Match what the platform asks for so crops and previews don’t surprise you.
Keep heroes and inline images under your layout width so the page doesn’t jump, and under attachment limits when you’re emailing.
Run one width or preset across a folder so every listing lines up in the grid.

Making it smaller usually still looks sharp. Making it bigger invents pixels; you’ll see softness or blockiness no matter which app you use. We resample with a decent filter so enlarging isn’t worse than it needs to be.
Leave aspect ratio locked: change width and height tracks along. Turn the lock off only when you deliberately want a squashed or stretched frame.
Examples people still reach for: 1080×1350 portrait posts (Instagram-style), 1280×720 for YouTube thumbs, 1584×396 for a LinkedIn banner. Platforms change specs sometimes, so double-check their help pages if something gets rejected.
In the editor you can load many files and apply the same width/height or preset to each. Good when every product photo needs the same long edge.
Other tools on the site work the same way: open, edit, download.
