Keep document processing out of your core application

Dependable document conversion and editing takes more than a standalone library. DocBox provides one clear integration boundary, so your team can focus on the workflow that makes your product valuable.

One versioned API

Every tool has a fixed route and a strictly validated contract. That keeps your integration predictable as the document flow grows.

Made for real business files

Work with HTML, DOCX, XLSX, PDF, PNG and JPEG—formats that appear every day in business processes and customer-facing products.

Dependable background jobs

Track longer work through clear states and download results only after every output has passed validation. DocBox publishes no partial result on failure.

Two clear processing flows

From source file to useful result

Use direct conversion when you immediately need one PDF. Choose artifacts and jobs for every other tool and for results that need more processing time.

1

Supply the source

Send HTML, DOCX or XLSX directly to PDF conversion, or upload a supported file as a private artifact.

2

Choose the tool

Start one focused job for conversion, PDF editing, templates, spreadsheets, images or metadata.

3

Use the result

Receive a PDF directly, or track the job until it completes and then download every published result artifact.

Supported input

HTML DOCX XLSX PDF PNG JPEG

Possible results

PDF PNG HTML XLSX JSON

Artifacts are temporary and expire exactly 24 hours after publication; DocBox deliberately is not a document archive.

One toolbox, 17 focused capabilities

Build the document flow your product needs

Every tool performs one clearly bounded task and creates a new result. Source and overlay artifacts remain unchanged.

Convert and render

Create clean images or PDF output and turn pages into PNG.

  • document.convert-to-pdfHTML, DOCX or XLSX to PDF
  • pdf.render-pagesPDF pages to PNG
  • image.to-pdfPNG or JPEG on a controlled A4 page
  • image.normalizeApply orientation and remove metadata

Organise PDFs

Compose new documents and control exactly which pages appear where.

  • pdf.mergeCombine 2–10 PDFs
  • pdf.splitSplit by intervals or ranges
  • pdf.extract-pagesSelect, repeat and reorder pages
  • pdf.rotateRotate all or selected pages

Finish and protect PDFs

Add visible marks, make content static or protect the result.

  • pdf.watermarkText or image behind the content
  • pdf.stampText or image above the content
  • pdf.flattenMake form fields and annotations static
  • pdf.encryptApply a password and usage permissions

Templates, images and metadata

Populate controlled templates, annotate images and manage allowlisted PDF metadata.

  • html.render-templateSafely place typed values in HTML
  • xlsx.populateFill cells, repeats, page breaks and QR codes
  • image.annotateAdd text and QR overlays
  • pdf.metadata.readRead a bounded metadata projection
  • pdf.metadata.writeUpdate allowlisted metadata fields
Designed with boundaries

Keep control of your documents and integration

DocBox is designed to make the conversion capability useful without widening the trust boundary around it.

Every request authenticated

Every public request requires an active DocBox API key in the X-DocBox-Api-Key header.

Ownership per API key

Only the same active API key can use, inspect, download, cancel or clean up its artifacts and jobs.

Private and short-lived

Source and result artifacts expire after 24 hours. DocBox does not retain them as a permanent document archive.

Predictable failures

Safe error codes, trace IDs and atomic publication help your integration respond without logging document contents.

A complete document flow in four fixed steps

Upload a source, start exactly one tool, track the job and download the result. The public API keeps every step explicit and controllable.

Base URL: https://api.docboxtools.com
