FAQ

Image resizer: questions

Are my photos uploaded?

No. The file is read by your browser and processed on your device; nothing is uploaded to a server, so there is nothing for us to keep.

What is the difference between Fit and Fill?

Fit scales the photo so all of it shows inside the size you chose, which can leave a smaller side. Fill covers the whole frame and crops what does not fit, so the output is exactly the size you asked for.

What size is an Instagram post?

1080 by 1080 for a square post, 1080 by 1350 for portrait and 1080 by 1920 for Stories and Reels. The presets here use those sizes.
