Smart crop or fit

Frequently asked questions
How do I resize multiple images at once?
Drop all of them into the resizer, choose a size, and click Resize. Download each one or click Download all to get a ZIP.
What size should an Instagram post be?
1080 × 1080 pixels for a square post, 1080 × 1350 for portrait, and 1080 × 1920 for Stories and Reels. All three are built-in presets.
Will resizing reduce quality?
Making an image smaller keeps it sharp. Making it much larger than the original adds no new detail — use the AI Upscaler for that.
Does it keep the aspect ratio?
Yes, by default. In Pixels mode, unlock the chain icon to set an exact width and height instead.
Are my images uploaded?
No. All resizing is done in your browser and nothing is sent to a server.
