Questions
Does this upload or store my files?
No. Parsing and previews stay in this browser tab. Contents and filenames are not sent to analytics, and no server or cookie storage is used.
What are the limits?
Up to 10,000 requests. Transferred size uses the recorded transfer size or known body plus header bytes; unavailable sizes display zero. Details may contain credentials, so no export or sharing service is provided.
