Frequently Asked Questions
How large a file opens?
Tens of megabytes smoothly via chunked rendering — only visible pages sit in DOM. Editors crash where this streams.
Search in huge files?
Yes — incremental search scans chunks with match counts. Thousand-hit queries paginate instead of freezing.
Editing too?
Viewing optimized; large edits belong in proper editors or sed. Copy sections out for modification elsewhere.
Is file content uploaded?
No — reading streams locally via FileReader. Content never leaves your device.
