Before
0 / 400,000After
0 / 400,000UTF-8 only · up to 400,000 characters, 12,000 lines, or 512 KiB per file · imported line endings stay exact until that box is edited; the browser editor then uses LF · very different texts may need to be split into sections.
What counts as a change?
Comparison is line by line and preserves exact characters, including Thai, emoji, spaces, blank lines and LF, CRLF or CR endings. A removed and added line in the same change block is shown as “changed,” with before and after text kept separate.
Does the text leave this device?
No. Contents are read, compared and exported in this browser. Text, filenames and report contents are not sent to a server or analytics.
Which report formats are available?
Download a readable TXT report or a table-based HTML report. User text is escaped as inert content in HTML, and the report blocks scripts and external connections.
