The Bytefuse API

Document work, distilled
to a single call.

Compress, convert and extract from PDF, DOCX and image files over one REST API. No SDK, no async plumbing — every tool is a plain HTTPS request that returns a finished file.

The toolkit

Three families of tools

Each is a single, focused endpoint. Call it from any language — here are the three documented so far.

01Compresspdf.compressShrink PDFs by up to 85% with quality held steady — strength scales to your plan tier.02Convertconvert.documentPDF ↔ Word, PDF → image, image → PDF and more, with formatting kept intact. AI vision for hard scans.03Extract tablespdf.to_xlsxDetect tables in a PDF and rebuild them as a typed Excel workbook — one sheet per table.

How it behaves

Learn it once, everywhere

Three things hold true of every tool. Internalise them and the whole surface becomes predictable.

1

One key, every tool

Authenticate once with a dt_live_ API key or a dashboard JWT. Light tools even run with no credentials at all.

2

Pay only for success

Credits are debited before the work and refunded automatically if a call fails. You are charged if and only if it succeeded.

3

Synchronous by default

Core tools finish the work in-request and hand back a ready download URL — no jobs to poll, no webhooks to wire.

Hello, world

Your first call

Compressing a PDF runs on the free-try path — no key required. Here it is in three languages; the Quickstart walks through the whole round-trip.

curl -X POST https://api.bytefuse.in/api/v1/compression/single \
  -H "Content-Type: application/json" \
  -d '{
    "file_data": "JVBERi0xLjQK...BASE64_PDF...",
    "filename": "report.pdf"
  }'

Then unlock the rest

Create a key in your dashboard to lift the anonymous rate limits and reach the full catalog — AI tools, OCR, redaction, certificates and more. Local backend? The same paths live at https://api.bytefuse.in/api/v1.
