Tips & best practices

  • Sensitive drafts and assets remain in your browser tab for the duration of the task.
  • Related tools in the text category appear below—chain tasks without re-uploading elsewhere.

Limitations

  • Very large files may stress browser memory—split batches on low-RAM devices.
  • Always verify platform rule changes on official docs—presets approximate common specs.
  • Common mistake — skipping spot-check on the first file in a batch: confirm settings on one sample before queueing hundreds.
