Frequently asked questions
Does resizing reduce file size too?
Usually yes, since fewer pixels means less data to encode, but the main goal here is changing dimensions. Use the Compress Image tool afterward if you want to squeeze the file size down further at the same dimensions.
What happens if I unlock the aspect ratio?
You can set width and height independently, which will stretch or squash the image if the ratio doesn’t match the original. Keep it locked unless you specifically want that effect.
Are the social media presets exact?
Yes, they match the current recommended dimensions for each platform (e.g. 1080×1080 for an Instagram square post). Platforms occasionally change their preferred sizes, so double-check if it’s been a while.
