Neon plan limitations
The file size limit is 20MB for the free Neon version. Here's the good news: There is no limit for the total uploads for a padlet. If you can upload it, you can post as many similar files as you please. 🦄
You can make up to three padlets. You can free up space by deleting or archiving padlets you no longer use.
There's no limit to the number of users you can share a padlet with. They can even add to the padlet at the same time!
