Two things decide it: the font, and how it shapes your script
This tool ships with fonts for 20 languages and scripts, and whether yours is one of them comes down to two separate questions: does a bundled font actually contain every letter your language needs, and does that font draw conjuncts, vowel signs and joined letters the same way in the file you download as it does on your screen. Both are checked against the real font files rather than assumed, which is what this page reports.
The table further down is checked against that same coverage data by a test that fails the build the moment the two disagree, so it cannot quietly drift from what ships. It shows a selection: the full list of all 20 languages and scripts lives on the Sign page's languages card, with its own row for each one.
A missing letter is flagged while you type, not after you download
As you type, the editor checks every character against the font you picked and tells you the moment one cannot be drawn, switching automatically to a font that can and naming the change. That check runs from the same generated glyph data the export itself uses, not a guess made on the fly.
If a character still cannot be drawn by anything bundled, because it belongs to a script this tool has no font for at all, the download itself refuses rather than quietly producing empty rectangles where your text should be. You find out before you have filled in the whole form, not after.
Hebrew, Arabic and Urdu boxes grow the way you actually write
A Hebrew or Arabic text box grows leftward from a fixed right edge as you type, the same direction the script itself runs, instead of stretching rightward the way a left-to-right box does. Letters join and change shape depending on their neighbours in Arabic and Urdu, the way handwriting actually connects.
That direction is not only a screen effect: the exported PDF keeps the underlying characters in the correct order too, following the Unicode bidirectional algorithm from the box's own declared direction rather than guessing it from the text. What you see while typing is what opens in the downloaded file.
Eight of the twenty languages, and what to know about each
| Language | Font that draws it | Handwriting face? | What to know |
|---|---|---|---|
| Hebrew | Heebo, or Gveret Levin for a handwritten signature | Yes, Gveret Levin or Amatic SC | Grows leftward from a fixed right edge; vowel points placed correctly for the download, not just on screen. |
| Arabic | Scheherazade New, or Vazirmatn | No | Letters join like handwriting; box grows leftward from a fixed right edge, same as Hebrew. |
| Urdu | Scheherazade New, or Vazirmatn | No | Same two fonts as Arabic; both are upright, not Nastaliq, the sloped calligraphic style Urdu is usually set in. |
| Devanagari (Hindi) | Mukta, or Kalam for a handwritten look | Yes, Kalam or Tillana | Conjunct letters and vowel signs reordered and reshaped correctly for the download; the same fonts cover Marathi too. |
| Bengali (Bangla) | Noto Sans Bengali, or Hind Siliguri | No | Noto Sans Bengali draws six rare conjunct clusters slightly differently in the download than on screen, named below; Hind Siliguri has none of those six. |
| Punjabi (Gurmukhi) | Mukta Mahee, or Tiro Gurmukhi | No | Ships on these two, not the Noto face: Noto Sans Gurmukhi breaks the download on common words such as the surname Singh, written ਸਿੰਘ. |
| Telugu | Anek Telugu, or Suranna | No | Ships on these two, not the Noto face: Noto Sans Telugu miscrafts a cluster inside the state name Andhra Pradesh itself, ఆంధ్రప్రదేశ్. |
| Japanese | Noto Sans JP | No | Covers hiragana, katakana and the two government kanji lists, 2,999 characters, not all of Han; anything outside them is flagged as you type. |
This is a selection, not the full list: it favours the languages with something specific to say, a right-to-left direction, a named divergence, or a script limit, over the ones that simply work end to end. Every one of the 20 languages and scripts has its own row on the Sign page's languages card.
What does not match perfectly, said plainly rather than buried
- 1Bengali: Noto Sans Bengali draws six rare conjunct clusters slightly differently in the downloaded file than on screen; Hind Siliguri, the second bundled Bengali font, has none of those six.
- 2Punjabi and Telugu: both ship on a font other than the default Noto one, because Noto Sans Gurmukhi and Noto Sans Telugu each miscraft a cluster common enough to break ordinary words in that language.
- 3Urdu: the two bundled fonts draw every letter and join them correctly, but both are upright. Urdu is conventionally set in Nastaliq, a sloped, cascading style, and neither font offers it.
- 4Chinese, Japanese and Korean: each covers a defined, curated set of characters rather than the full Han block Unicode allows, and anything outside that set is flagged as you type rather than left to guess.
- 5Emoji: no bundled font draws it at all, in any language.
Some scripts have no bundled font yet
A handful of scripts have no bundled font at all today: Gujarati, Kannada, Odia, Sinhala, Khmer, Lao, Burmese, Amharic, Armenian and Georgian among them. A form in one of those languages cannot be filled or signed here yet, and the tool would tell you the moment you tried rather than let it slip into a download.
Languages get added on request, not on a fixed schedule, so this list is honest about today and likely to shrink. Ask for yours and it moves to the front of the queue.
Try it in your own language before you trust it with a form
Open the free PDF signer, pick your language's font from the menu, and type a real line to see it filled in before you commit to a whole form. Nothing you type leaves your device, there is no account to create, and a draft of your work saves itself in this browser if you need to come back to it.
