Convert HTML files to PDF with Aspose.HTML Cloud API


HTML files are usually the basic building block of the websites. HTML file format lets you manipulate or organize text, images, tables or any other page contents. Modern web applications generate reports or information in HTML format because almost all devices support this format without needing any additional or complex configuration. However, often we need to protect a document from modifications by means of document privileges or digital signing. You may also need to archive data for longer periods of time. In such cases, you can convert HTML files to PDF documents. There could be many other reasons to convert HTML files to PDF. Here we will be discussing this use case in connection with Aspose.HTML Cloud APIs.

Aspose.HTML Cloud API for HTML to PDF Conversion

Aspose.HTML Cloud is a REST API that allows you to convert or manipulate HTML documents and several other Supported File Formats. You can use it on any platform you may plan to work with, because it can be used with cURL commands or SDKs including PHP, Ruby, Python, Node.js and many others. You only need to sign up for free and test the API in its full capacity. We have already compiled all the necessary information about Creating and Managing accounts in the documentation article.

Convert HTML files to PDF

Here we will be discussing two popular but different use cases of HTML to PDF conversion using cURL. First of all, let’s consider the conversion of HTML file to PDF where HTML file exists on your local disk and the result PDF will be saved in your storage.

  1. Get your App Key and App SID after signing up
  2. Get JSON Web Token
  3. Call the API
  4. Generated PDF file will be saved in a specified folder on the Storage

Below code snippet shows all these steps and converts the HTML file to PDF:

Input HTML file displayed by browser (Google Chrome)

HTML to PDF rendering

Output PDF file generated by Aspose.HTML Cloud API

PDF output

Likewise, you can also convert HTML to PDF by using a URL. In response to your request, a PDF file will be received which you may save in your local file system. Below are the steps for converting a web page to PDF by specifying the URL.

  1. Get your App Key and App SID after signing up
  2. Get JSON Web Token
  3. Call the API where you need to pass the URL as parameter
  4. Generated PDF file will be saved in your local file system

Following code snippet follows these steps and can simply generate a PDF document:

Webpage displayed by browser (Google Chrome)

Source HTML file

Output PDF file generated by Aspose.HTML Cloud


As you can notice the generated PDF file is a true depiction of WYSIWYG rendering. The API performs high fidelity rendering thus it could be a perfect candidate to be integrated into your applications. Feel free to test the APIs prior to purchasing it and we would love to hear your concerns, questions or suggestions via our Free Support Forums.

Aspose Cloud December Pricing Update

Simplifying Pricing for New Customers

We have updated the Aspose Cloud pricing structure to simplify it for new customers. Previously some API calls were “chargeable” while other API calls were not. If an API call created a document or meaningful result, then it was chargeable. If an API call did not create a document or result, then it was not chargeable. However, there were some ‘grey areas’ with certain Aspose Cloud products where customers were confused about whether they should be charged for some calls.

To resolve this issue we have updated our pricing to now charge for every API call made, regardless of what the API call does. At the same time, the cost of each API call on the new pricing scheme has been reduced by 1/3.

How does this affect Existing Customers?

Since the effect of this change is different for every customer we have not automatically switched existing customers to the new pricing. Instead as with every pricing change we have “grandfathered” existing customers who will continue to be charged based on the pricing when they signed up.

If you are an existing customer who wishes to switch to the new pricing, you can do this by visiting the “Buy Now” page within your Aspose Cloud account.

You can find more information on the new pricing here:

Aspose.Storage Cloud has been Discontinued

Aspose Storage Cloud

Aspose is glad to share with you that Aspose.Storage Cloud API features are now more simplified. Files and folders storage and their manipulation are no more dependent on the separate Aspose.Storage Cloud API, however, these features have been integrated within every Aspose Cloud API. To be very precise, “Aspose.Storage Cloud has been discontinued as a separate product”.

What existing users can do?

Aspose.Storage Cloud API and following SDKs will remain available on the public repositories like GitHub, NuGet, etc for the existing customers until 31.12.2020:

  • Aspose.Storage Cloud SDK for .NET
  • Aspose.Storage Cloud SDK for Java
  • Aspose.Storage Cloud SDK for PHP
  • Aspose.Storage Cloud SDK for Python
  • Aspose.Storage Cloud SDK for Ruby

Therefore, we recommend updating your applications to the latest versions of SDKs / Endpoints as soon as possible.

Aspose.Storage Cloud will neither be available for purchase separately nor as a part of Aspose.Total Cloud Product Family any more. However, the technical support welcomes you for any further queries about the migration to the latest versions.

How to work with new APIs?

The below sample shows how you were using Aspose.Storage Cloud API to upload the file to Cloud Storage:

// cURL example to upload file to Cloud Storage
curl -v "" \
-X PUT \
-T sample.docx \
-H "Content-Type: multipart/form-data" \
-H "Accept: application/json" \
-H "Authorization: Bearer <jwt token>"

Now you can achieve this using any of the Aspose Cloud APIs. Below sample shows Aspose.Words Cloud API to upload the file to Cloud Storage:

// cURL example to upload file to Cloud Storage
curl -v "" \
-X PUT \
-T sample.docx \
-H "Content-Type: multipart/form-data" \
-H "Accept: application/json" \
-H "Authorization: Bearer <jwt token>"

The most notable change is the Base URL of the API.

Show Data Labels Over the Maximum of the Chart with Aspose.Slides Cloud 19.10

Our Aspose.Slide Cloud monthly releases continue, and we’re happy to announce the latest version, 19.10. It’s available on production server. It improves the Chart manipulation feature of the API .It includes a new chart property ShowDataLabelsOverMaximum to show data labels over the maximum of the chart, custom HTTP headers support and issue fixes in API Explorer. Check the release notes of this version for a complete list of enhancements and improvements.

Let me give you a quick overview of some of these features, carried in this new release.

Add Chart with ShowDataLabelsOverMaximum

While working with charts, there is a scenario where your maximum data value is greater than the maximum value of the axis and data goes off the chart canvas and data label does not show up in the chart. With the introduction of new property now you can specify to show data labels over the maximum of the chart in that case.

For example, in following chart maximum value of the vertical axis is 6 but Column 04 in Category 2 has value 7, so the data label is not reflected in this case.

Now starting from this release, you can control the Data Labels appearance in discussing scenario. You can set ShowDataLablesOverMaximum to true and get the data labels in the chart:

A cURL example to update the Chart properties:

Custom HTTP Header Support

Custom HTTP headers are commonly meant to provide additional information in the HTTP request. These are used for troubleshooting, informational purposes, and even implementing particular logic on the server-side.

In this release, we have implemented a new feature to pass custom HTTP headers in Aspose.Slides Cloud SDKs. The SDKs are wrapped around Cloud APIs and support all the features of Aspose.Slides Cloud API in your favorite programming language without worrying about the underlying REST API calls.

Here you can check how to pass custom HTTP header using Aspose.Slides Cloud SDK for .NET:
