Get Started NowCustomer Reviews
We have found our experience with Zamzar over the years we have used it to be fantastic.
They were receptive to a tiered pricing structure as our requirements changed, have a friendly support team that is always helpful and their API that we use daily to send documents to for conversion has always been available and had no issues.
Robin L
The service just works. We've tried other file conversion services in the past, and the results were very disappointing.
With Zamzar, the results are consistently good. Also, their support is friendly and responsive.
Bruno D
We needed a product to upload HTML content, convert and download as a PDF. Zamzar's API provided not only the service required but easy to understand stepped-process to implement.
This business process was critical - but I don't believe we ever had a failure over years of daily use.

Firewalls
Zamzar uses multiple different firewall technologies to ensure that different components of its systems are logically isolated from one another.
Using PPT with PHP
Powerpoint files can be manipulated through a number of open source tools. You could consider using the PHP Presentation open source software library which is written in pure PHP (and licensed under LGPL version 3). It supports both the reading and writing of Powerpoint files, but does have some limitations around rendering - for example losing styling in some cases. It is however actively updated so over time bugs and issues are being fixed.
Another option is to use LibreOffice Impress, this is an actively developed solution for reading and writing Powerpoint files, however it's automation API is limited in PHP. It does have some fairly well documented rendering issues too, for example with SmartArt presentations. Think carefully before using it if rendering is an important cog in your conversion needs, but as a low cost solution this might suffice.
If you need commercial software that renders as accurately as the native Microsoft Office tooling then you could consider using the Zamzar API. With a dedicated support team, code examples in many of the major languages including PHP, simple low cost conversion credits and support for direct import and export to S3, it may cover most of the use cases you require. Feel free to reach out to our support team with any questions or dip into the getting started guide in our docs.

Using PDF with PHP
There are a multitude of different open source PDF manipulation libraries within PHP to choose from. FPDF is a library that allows you to generate PDF files with pure PHP with no need to use the PDFlib library. According to the license agreement referenced in the FAQ you can use FPDF with no restrictions in both a commercial and non-commercial environment.
Another open source PHP option is mPDF which generates PDF files from UTF-8 encoded HTML. It is based on FPDF and HTML2FPDF and was designed to be able to quickly create PDF files from a website template. It supports Right to Left languages as well as a host of other features that you can find listed here.
TCPDF is a great PHP PDF library for creating PDF files from as little as two lines of code. It doesn't require any external libraries for the basic creation of PDF files and is arguably the most extensive PDF PHP library that we have come across. You can see a full list of features here. It is actively maintained by Nicola Asuni in this Github repository.
If you don't want to use an open source offering you might want to consider using the Zamzar API. With a dedicated support team, code examples in many of the major languages including PHP, simple low cost conversion credits and support for direct import and export to S3, it may cover most of the use cases you require.
