FAQ
What is the best image size for a LinkedIn post?
1200×1350 pixels (4:5 portrait) takes up the most feed space and is the preset most creators use. LinkedIn banners are 1584×396 and profile photos 400×400 — all available as one-click presets above.
Does resizing here upload my image anywhere?
No. Resizing happens entirely in your browser on your own device. Nothing is sent to a server, which also makes it faster than upload-based resizers.
How does the tool handle a different aspect ratio?
When you pick a preset, the image is scaled to fill the exact dimensions and centered, cropping the overflow — the same way social platforms crop. Uncheck presets and use lock aspect ratio to scale without cropping.
