Dear miniExtensions Community, We hope this message finds you well. As part of our ongoing efforts to enhance the user experience and optimize system performance, we would like to inform you of an upcoming change regarding the Public URL for Attachments. Starting December 21, 2023 5:00 AM (UTC), the Public URL for Attachments will no longer support files exceeding 30MB in size. This adjustment is aimed at ensuring smoother operations and faster access to shared content. This is now a good time to use an extension to calculate the file size of the attachment field to determine which files are going to be affected. > **[Calculate Airtable Attachment File Sizes - miniExtensions for Airtable](https://miniextensions.com/airtable-attachment-sizes/)** > > Identify which records have the attachments that are taking up the most storage space. This extension helps making the cleaning up process easier! If you are working on images and found files that are over 30MB, you can use this extensions to make the file size lower. > **[Compress, Resize, or Rotate Images on Airtable - miniExtensions for Airtable](https://miniextensions.com/bulk-image-compression-on-airtable/)** > > A tool to modify the images in bulk on Airtable with a single click!
