POST /v1/pdf/from-html HTML to PDF
Raw HTML and CSS rendered by a real, sandboxed Chromium — web fonts, flexbox, grid and JavaScript behave exactly as in a browser tab.
Everything the API can do
One multilingual rendering pipeline behind every endpoint — the same fonts, the same error envelope, the same zero-retention handling.
Inputs & outputs
Send whatever you have — markup, a link, your data or Markdown — and get a PDF or an image back.
POST /v1/pdf/from-url URL to PDF
Point at a public page and get it back as a print-ready PDF.
POST /v1/pdf/from-template Templates + your data
Send a LiquidJS template and a JSON payload; the template runs in a sandbox and the result is rendered to PDF — ideal for invoices and reports.
POST /v1/pdf/from-markdown Markdown to PDF
Send Markdown — from an AI agent, a note or an automation — and get back a clean, print-ready PDF with tables, lists and code, in any language.
POST /v1/image/from-html · /from-url · /from-template · /from-markdown HTML, URL, template or Markdown to image
PNG, JPEG or WebP for social cards, receipts, chart snapshots and thumbnails — from the same inputs as PDFs, including templates with your data and Markdown. Capture the full page, the viewport or a single element, at 2× or 3× for sharp output.
POST /v1/pdf/merge · /v1/pdf/split Merge and split PDFs
Combine existing PDFs into one, or cut one into parts by page, range or every N pages. Pages are copied as they are, so every script looks exactly as in the original files. Split parts take the same output options as a merge — document properties, compression, a password or PDF/A — and files made with Legebla keep their searchable text in PDF/A.
Every language, archival-ready
The reason Legebla exists: documents that read correctly in every script your customers use.
25 languages · CJK · RTL · emoji Zero tofu
Full Unicode coverage with OS-level fonts baked in — Chinese, Japanese, Korean, Arabic, Hebrew, Hindi and more. No missing-glyph boxes, no broken right-to-left layout.
options.pdfa: "PDF/A-3b" Archival PDF/A that stays searchable
PDF/A-3b output from every render endpoint keeps the selectable, searchable text exactly as rendered — Hindi, Arabic, Chinese, emoji and the rest — along with accessibility tags and the document language.
options.zugferd ZUGFeRD e-invoices
Embed your EN16931 (CII) invoice XML into a PDF/A-3 file for ZUGFeRD / Factur-X e-invoicing — built on the same searchable, multilingual base.
options.watermark Watermarks in any language
Drawn with the same fonts as the page, so an Arabic, Chinese or Hindi "DRAFT" renders correctly — centered or tiled, with your own opacity. Or stamp your logo as an image watermark.
options.metadata Document properties
Set title, author, subject, keywords, creator and language — in any script — for PDF viewers, search and document managers.
Control the capture
Shape the page before it becomes a document.
css · javascript · waitFor.delayMs · lazyLoad Adjust the page before capture
Inject CSS or JavaScript (hide cookie banners, fix print layout), wait a fixed delay for late charts, and scroll the page so lazy-loaded images appear.
from-url: headers · cookies · auth Pages behind a login
Render pages that need a session cookie, custom headers or HTTP Basic auth. Credentials are sent only to the target URL's origin — never to CDNs, analytics or redirects elsewhere.
options.compress Smaller files
Recompress and resize images and store repeated images and fonts once — handy for email attachments and upload limits. For some complex scripts and emoji the copy-and-search text may differ after compression; the response warns you when that applies.
Security & delivery
Your documents are processed in memory and handed back — or straight to you.
zero data retention Nothing stored by default
Renders run in isolated, ephemeral workers. Nothing is written to a database or disk by default — the document is discarded after delivery.
options.encryption Passwords and permissions
AES-256 encryption with a user and/or owner password, and control over printing, copying, editing, annotating and form filling.
upload Deliver to your own storage
Pass a pre-signed PUT URL (Amazon S3, Cloudflare R2, Google Cloud Storage, Azure Blob) and the file goes straight from memory into your own bucket. Nothing is kept on our side.
Build & test
Made to be wired into code or automations without guesswork.
GET /v1/openapi.json OpenAPI 3.1 spec
A complete spec is the single source of truth — import it to generate a typed client in any language, or call the REST endpoints directly.
options.sandbox Sandbox mode for testing
Wire up a workflow with real output that doesn't count against your quota. Sandbox files are stamped "SAMPLE — sandbox" on every page.
