Xenmark's free browser tools are built on open-source software. This page lists everything that reaches your browser when you use one, and reproduces the full licence text for each. Several of these licences require exactly that: the text has to travel with the software, and a link to it does not satisfy them.
The package list is taken from the tools' own generated notice file rather than from memory, so it is what actually ships; the icons and the fonts are vendored rather than installed, so they are recorded here by hand and are named in their own sections below. Xenmark's own code is not open source. The tools are free to use; that is not the same thing, and nothing here licenses Xenmark's code for reuse.
1. What reaches your browser
Five packages:
| Package | Version | Licence |
|---|---|---|
| @astrojs/preact | 6.0.5 | MIT |
| @preact/signals | 2.11.2 | MIT |
| @preact/signals-core | 1.14.4 | MIT |
| pdfjs-dist | 6.3.289 | Apache-2.0 |
| preact | 10.29.8 | MIT |
Packages used only for building, testing or checking the tools — Astro, TypeScript, the Vite toolchain — never reach a browser and are not listed. Adding them would make this page wrong rather than thorough.
2. PDF.js assets
pdfjs-dist also contributes four static files that are copied into the site rather than bundled into its JavaScript:
- The PDF.js worker — Apache-2.0, as the package.
- One character-map bundle — carries Adobe's BSD-3-Clause CMap terms in addition to the package's Apache-2.0 licence, so both texts apply.
jbig2.wasm— PDFium's JBIG2 decoder, BSD-3-Clause with parts under Apache-2.0, inside Mozilla's Apache-2.0 wrapper. It exists so scanned drawings can be drawn.openjpeg.wasm— the OpenJPEG JPEG 2000 decoder, BSD-2-Clause, inside Mozilla's BSD-2-Clause wrapper. That licence grants no patent rights; this was considered and accepted when the decoder was admitted on 17 September 2026.
All six licence texts covering those files ship inside the tool site itself, under pdfjs/licenses/, beside the files they cover. The build fails if either decoder ships without them. Each one is also reproduced in section 5 below.
Deliberately not copied, because a reader who knows PDF.js will wonder: standard-font bundles, the colour-management WebAssembly module, the JavaScript decoder fallbacks, ICC profiles, sandbox resources and source maps.
3. Icons
42 Lucide icons are vendored as SVG markup and rendered inline in the page. There is no npm package, no sprite sheet and no icon font, so nothing appears in the table above — the geometry ships inside the HTML.
The set carries two licences, not one. Lucide is ISC, copyright © 2026 Lucide Icons and Contributors. The icons Lucide derived from the Feather project are additionally MIT, copyright 2013–present Cole Bemis. Of the icons used in the tools, exactly one is Feather-derived: type. The upstream licence file covers both and is reproduced in full below.
4. Fonts
This whole site uses three typefaces — Instrument Serif for headings, Geist for body text and Geist Mono for labels — and serves them from Xenmark's own domain rather than fetching them from Google Fonts. That is a privacy decision before it is a licensing one: a page that loaded a font from another company would send every visitor’s IP address there before a word rendered, and the claim on the privacy page that these pages make no third-party request would be false. The tool pages stopped doing it first; the rest of the site followed on 22 September 2026.
Serving them ourselves means redistributing them, so their licence applies to us. Both are under the SIL Open Font License 1.1, which permits redistribution — bundled with other software, and with or without a fee — provided the copyright notice and licence travel with the fonts and the fonts are not sold on their own. Neither condition constrains anything Xenmark does here.
Eight files ship, 176 KB in total: Latin and Latin Extended subsets of each family, plus an italic for Instrument Serif. It is eight rather than eighteen because Geist and Geist Mono are variable fonts — one file carries every weight and the browser picks the instance — so the weights we use resolve to a single file per family and subset.
Both licence texts ship inside the tool site, under fonts/, beside the files they cover, and the build refuses to release the fonts without them. Each is also reproduced in section 5 below.
The same eight files are served from /fonts/ for the rest of the site, and their licence texts sit beside them there too. Google Fonts remains listed as a processor on the privacy page because the signed-in application still loads two different families from it; no page on this domain does.
5. Licence texts
Each text below is the complete licence, copied unchanged. Open one to read it; the text is present whether it is open or closed, so your browser's find-in-page will reach it either way.

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the
Work (including but not limited to damages for loss of goodwill,
work stoppage, computer failure or malfunction, or any and all
other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing
the Work or Derivative Works thereof, You may choose to offer,
and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this
License. However, in accepting such obligations, You may act only
on Your own behalf and on Your sole responsibility, not on behalf

names, trademarks, service marks, or product names of the Licensor,
except as required for reasonable and customary use in describing the

7. Disclaimer of Warranty. Unless required by applicable law or
agreed to in writing, Licensor provides the Work (and each

WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
implied, including, without limitation, any warranties or conditions

incidental, or consequential damages of any character arising as a
result of this License or out of the use or inability to use the

other commercial damages or losses), even if such Contributor
has been advised of the possibility of such damages.
9. Accepting Warranty or Additional Liability. While redistributing

and charge a fee for, acceptance of support, warranty, indemnity,
or other liability obligations and/or rights consistent with this

6. Xenmark's own code
Everything Xenmark wrote — the tools, their processing code, their content and their design — is proprietary. It is not open source and is not licensed for reuse, redistribution or modification.
The tools are free to use, including for commercial work, and files you create with them are yours. Free to use and open source are different things, and only the first is true here.
7. Standards material
No licence requires this and no attribution is owed, but it is the kind of thing a careful reader asks about. The greyscale JPEG encoder used when compressing a PDF uses the example quantisation and Huffman tables printed in the JPEG standard (ITU-T T.81, Annex K). Every baseline JPEG encoder carries the same numbers; they are numeric tables rather than protected expression.
8. Keeping this page current
This page was last checked against the tools' generated notice file, their vendored icon set and their vendored fonts on 22 September 2026. When a dependency of the tools changes, the notice file is regenerated by the build and this page is updated to match it in the same week. The icons and the fonts are not in that file — they are vendored, not installed — so a change to either has to be brought here deliberately. That is the most likely way this page goes wrong, and it already has once: the fonts were self-hosted on 22 September 2026 and reached browsers before this section named them.
