TSV to MHT Converter
Processing entirely on your device — large files may take a moment.
Convert MHT archives to PDF for clean printing, or extract the readable document from a saved page. If your files are still in TSV format, this page is the shortcut: TSV (Tab-Separated Values) is CSV’s cousin that uses tab characters as separators — common in bioinformatics, data-warehouse exports and Excel clipboard data.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the TSV format
TSV is CSV's tab-separated sibling: rows as lines, columns split by tabs, everything plain text. Its quiet superpower is the clipboard — copy a range in Excel or Sheets, paste into a text editor, and you are looking at TSV; paste it back and the grid restores. That round-trip makes it the Lingua franca of ad-hoc spreadsheet work.
The tab delimiter avoids CSV's comma-in-text quoting dance, at the price of being broken by any value that itself contains a tab — there is no standard quoting. Like CSV it is untyped, single-table, and happiest as a quick exchange or import format.
+ Strengths
- ✓Round-trips through the clipboard with spreadsheets
- ✓No quoting rules to worry about
- ✓Columns align visually in monospace editors
! Limitations
- −A tab inside any value corrupts the file
- −Untyped and single-table like CSV
- −Some tools assume CSV only
About the MHT format
HTML is the markup language of the web itself. A document is plain text decorated with tags that describe structure — headings, paragraphs, lists, links, tables, images — and browsers turn that structure into a rendered, styled page. It is both a format and a program target: CSS styles it and JavaScript makes it interactive.
As a document format, HTML's strength is universality: any device with a browser displays it, text stays selectable and searchable, and links make it navigable. Its weakness is that rendering depends on the surrounding CSS and viewport, so it is a flowing document, not a fixed-layout one — printing or archiving an HTML page is inherently an approximation.
+ Strengths
- ✓Displays on every device with a browser
- ✓Semantic structure: headings, links, tables, media
- ✓Text remains selectable, searchable and accessible
! Limitations
- −Final look depends on CSS and viewport
- −Not a fixed-layout or print format
- −Untrusted HTML must be sanitized before display

Frequently asked questions
Is this TSV to MHT converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
What about special characters and non-English text?
Everything is handled as UTF-8. When you export CSV for Excel, a UTF-8 BOM is included automatically so Chinese, Japanese, Korean and accented characters display correctly on both Windows and macOS.
Are formulas, styles or multiple sheets converted?
No — this conversion extracts the data itself into MHT. Formulas are exported as their current values, styling is not carried over, and multi-sheet workbooks convert sheet by sheet. For full fidelity between spreadsheet formats, exchange within the same tool family.
How large can my TSV file be?
Since everything runs locally in your browser, the real limit is your device memory rather than an upload cap. Files up to a few hundred megabytes are usually fine on a modern computer; extremely large ones simply take longer.
