This extension resizes images directly on Airtable. You just need to name the field where the images are stored and it will resize their dimensions + upload them to a new field. You can also set it up to automatically process any new records going forward (unlimited records).
Note: an additional feature that is not shown in the video is the ability to save the resized images as JPEG.
Works with standard file types: JPEG, JPG, PNG.
⚠️ file names are not maintained after being resized.
