Frequently asked questions

How do I resize an image to 400×400 pixels?

Drop your photo into the tool above — width 400 and height 400 are already set. Choose how it should fit and click Download.

What is the difference between “Crop to fill” and “Fit inside”?

Crop to fill covers the whole 400×400 area and trims the edges, so there are no borders. Fit inside keeps the whole picture and fills the empty space with a colour or transparency.

What aspect ratio is 400×400?

400×400 has an aspect ratio of 1:1. Photos with a different shape are cropped or padded to match it.

Are my photos uploaded?

No. FileCrafty resizes images directly in your browser, so your files never leave your device.

Does resizing reduce quality?

Making an image smaller keeps it sharp. Making it much larger than the original cannot add detail, so upscaled images may look soft.
