Frequently Asked Questions (FAQs)

Q: Will this affect existing preview and thumbnails?
A: No, this setting only affects files uploaded after the change.
Q: I have preview and thumbnails turned on, but they don't seem to be generating?
A: If you're in a Sandbox or Release Preview environment, confirm that file migration and file conversion processes (thumbnail and preview generation) aren't disabled (see Restricting File Migration and File Conversion in Sandbox & Release Preview Environments). If they aren't disabled or you're in a Production environment, see eXtendFiles Preview & Thumbnail Generation.
Q: Are there file size limitations for preview and thumbnail generation?
A: Without a dedicated image conversion service, file conversion for preview and thumbnail images is limited to files smaller than 200 MB. Larger files won't be sent for conversion due to their exponential increase in conversion time and potential delays in the shared conversion queue. When using a dedicated file conversion service (available as an eXtendFiles add-on), files larger than 200 MB will be considered for file conversion as well.
