Submit the HTML as document_content to DocRaptor, then inspect the resulting PDF using representative text from the language and styles you need. “Indian-language” can mean several scripts, including Devanagari, Bengali, Gurmukhi, Gujarati, Odia, Tamil, Telugu, Kannada, and Malayalam; there is no single font choice that fits them all.
1. Choose a font and confirm the renderer can shape the script
A font needs to do more than display individual characters: it must include the glyphs in your text, and the renderer must correctly shape the script, including substitutions and mark placement. Prince, the renderer documented by DocRaptor, describes Indic shaping and font fallback in its styling documentation.

For Devanagari and Hindi, Prince lists Lohit Devanagari and Noto Serif among font examples. Its Prince 13 release notes, dated November 2019, identify Indic2 OpenType shaping support as needed for newer fonts such as Noto Serif Devanagari and Nirmala. That is a renderer-version-specific statement; it does not establish which Prince version DocRaptor currently assigns to an individual account. Prince’s release history records support for shaping in Devanagari, Bengali, Gurmukhi, Gujarati, Oriya (now commonly called Odia), Tamil, Telugu, Kannada, and Malayalam. See the Prince 13 release notes and release history.
- Identify the language and script in the actual document rather than choosing a font based on the broad label “Indian.”
- Check that the font covers the characters, signs, and numerals your content uses.
- Check that the renderer supports the font’s shaping needs.
- Confirm that the font format and required weights are available in your DocRaptor rendering environment.
There are two practical font-supply routes: use a font already available to the renderer, or provide a web font with @font-face. The examples below use the second route.
2. Declare the font in HTML and apply it to your text
DocRaptor documents web-style @font-face declarations. Replace the sample font URL, family, language tag, and text with values for your own font and content. The font resource must be reachable by the rendering service.
<!doctype html>
<html lang="hi">
<head>
<meta charset="utf-8">
<style>
@font-face {
font-family: "IndianText";
src: url("https://your-host.example/fonts/your-script-font.woff2") format("woff2");
font-style: normal;
font-weight: 400;
}
.indian-text {
font-family: "IndianText", sans-serif;
}
</style>
</head>
<body>
<p class="indian-text" lang="hi">यहाँ अपना परीक्षण पाठ रखें।</p>
</body>
</html>The font-family value must match the font-family name declared in @font-face. Keep the fallback family as a safety net, not as proof that the requested font rendered every character: Prince can fall back when a glyph is missing. DocRaptor’s custom fonts documentation and custom fonts tutorial describe the font declaration and PDF workflow.
Account for format and text styles
DocRaptor says WOFF2 requires Pipeline 8 or higher. The public documentation does not establish which pipeline version is assigned to a particular account, so confirm compatibility before relying on WOFF2. Prince lists WOFF/WOFF2, TrueType, and OpenType support, but the DocRaptor pipeline requirement is the service-specific constraint to check.
If your document uses bold or italic, declare the corresponding font files and their matching font-weight and font-style values when available. Prince may synthesize bold or italic when a matching face is absent, which can change its appearance. Validate every style used in the finished document.

3. Submit the HTML as a PDF to DocRaptor
Send the HTML string as document_content to DocRaptor’s PDF API. The following Python example uses the documented API pattern; replace the API key and HTML with your own. The custom font URL inside the HTML must be accessible to DocRaptor.
import requests
html = """<!doctype html>
<html lang="hi">
<head>
<meta charset="utf-8">
<style>
@font-face {
font-family: "IndianText";
src: url("https://your-host.example/fonts/your-script-font.woff2") format("woff2");
font-style: normal;
font-weight: 400;
}
.indian-text { font-family: "IndianText", sans-serif; }
</style>
</head>
<body>
<p class="indian-text">यहाँ अपना परीक्षण पाठ रखें।</p>
</body>
</html>"""
response = requests.post(
"https://docraptor.com/docs",
auth=("YOUR_API_KEY", ""),
data={
"doc[document_content]": html,
"doc[document_type]": "pdf",
"doc[test]": "true",
},
timeout=90,
)
response.raise_for_status()
with open("indian-language.pdf", "wb") as pdf:
pdf.write(response.content)The example requests DocRaptor test mode, which returns a watermarked test document. Follow the current DocRaptor tutorial for the API workflow and account-specific production settings.
4. Validate the PDF with representative content
A PDF that shows visible text may still have used fallback for some characters. Test a short sample that reflects the real document, then inspect the output visually and, when relevant, check that text remains selectable and searchable.

- Include script-specific combinations, conjuncts, vowel signs, and marks—not only isolated basic letters.
- Include the numerals and punctuation that appear in production content.
- Check normal, bold, and italic text separately if the document uses those styles.
- Look for missing-glyph boxes, unexpected changes in letter forms, misplaced marks, and altered line breaks.
This validation is important because glyph coverage, shaping, and fallback are separate concerns. Prince documents automatic fallback and script shaping, but the output must be checked for your chosen font, text, and rendering environment.

5. Troubleshoot common font problems
| Symptom | Likely cause | What to check or change |
|---|---|---|
| Some characters appear as boxes or disappear. | The selected font may lack those glyphs, or the font resource may not have loaded. | Check font coverage for the actual text, verify the URL is reachable by the renderer, and confirm the CSS family name and selector apply to the text. |
| Text is visible but some characters look different from the intended font. | Prince may have used a fallback font for missing glyphs. | Check the font’s glyph coverage and inspect the PDF; Prince documents fallback behavior in its styling documentation. Where available, Prince’s prince-no-fallback mechanism can make missing glyphs warn rather than switch silently. |
| WOFF2 does not load. | The account may be using a DocRaptor pipeline below Pipeline 8. | Confirm the account’s pipeline version with DocRaptor or use a font format supported by that environment. |
| Conjuncts or marks are incorrectly formed or positioned. | The font may not suit the script, or the rendering pipeline may not provide the required OpenType shaping behavior. | Try a font intended for the target script, reduce the test to representative text, and check the renderer version with DocRaptor. |
| Bold or italic text looks wrong while regular text looks correct. | The corresponding face may be missing and synthesized. | Provide the matching weight or style file where available, declare it in @font-face, and render that style again. |
| Legacy text is incorrect despite a suitable font. | The input may use a legacy-font encoding rather than Unicode. | Confirm the text contains the intended Unicode characters. Legacy-encoding conversion is outside the documented font workflow and needs separate handling. |
If the problem persists, reduce the document to a small HTML file with the same font and text. This isolates font loading and shaping from other page content. Ask DocRaptor which rendering pipeline/version applies to your account; the public documentation does not establish individual account assignments.

For website screenshots rather than generated PDFs, ScreenshotNeo is a screenshot API and MCP server: one GET request can return a PNG, JPEG, WebP, or PDF. It removes cookie banners, newsletter popups, and chat widgets before capture; bot checks, blank pages, and failed loads are never billed. AI agents can take screenshots through its MCP server, and the free plan includes 1,000 screenshots a month with no card; paid plans start at $5 for 3,000.
ScreenshotNeo is not a replacement for DocRaptor’s HTML-to-PDF workflow when you need a composed document with embedded Indian-language fonts. For a website capture, here is the one-call cURL example; see the ScreenshotNeo documentation for options and API details.
