From zero to first PDF in a minute

No SDKs to learn, no services to configure. Three steps and you're converting.

  1. 1

    Create an API key

    Sign up for free and generate a key in Settings > API keys. Your 1,000 monthly credits are ready immediately.

  2. 2

    Call the endpoint

    Send one HTTP request with your key in the Authorization header. Works from any language or framework.

  3. 3

    Get your file back

    The response is your PDF or image, ready to store, email, or serve. Each call costs exactly one credit.

Built for the jobs you'd rather not build

PDF rendering and screenshot capture are the classic "sounds easy, becomes a project" features. Skip the browser farm and ship the feature instead.

Frequently asked questions

Everything you need to know about the free tools API

Are the Ploi Cloud tools really free?

Yes. Every user receives 1,000 API credits per month at no cost, and they reset automatically on the 1st of each month. Each tool call costs one credit, and checking your balance or the service health is always free.

What can I do with the free tools API?

You can convert web pages, HTML, Markdown, and Office documents to PDF, merge multiple PDFs into one file, and capture screenshots of web pages or raw HTML in PNG or JPEG format.

Do I need a credit card to use the tools?

No. Create a free Ploi Cloud account, generate an API key in Settings > API keys, and start making requests. The 1,000 monthly credits are included with every account.

Which Office formats can I convert to PDF?

The office conversion endpoint supports .docx, .doc, .xlsx, .xls, .pptx, .ppt, .odt, .ods, .odp, .rtf, .txt, and .csv files.

How do screenshots work and what options are there?

Send a URL or raw HTML to the screenshot endpoints and you get an image back. You can set the viewport width and height between 100 and 4096 pixels and choose PNG or JPEG output. The default viewport is 1920 by 1080 pixels.

How do I authenticate my requests?

Create an API key in Settings > API keys and pass it in the Authorization header as a Bearer token. The same key also works for the rest of the Ploi Cloud API.

What happens when I run out of credits?

Requests return a 402 response until your credits reset on the 1st of the next month. You can check your remaining balance at any time for free via the balance endpoint or in Settings > API credits.
