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 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. Feel free to reach out to our support team with any questions or dip into the getting started guide in our docs.

Using PNG with PHP
Depending on your specific needs there are a number of commercial and open source libraries that will enable you to convert or manipulate PNG files. One consideration is whether you want the outputted PNG file to be transparent. You could consider using GD which is a good PHP image library with extensive documentation.
Another open source option is ImageMagick which has a very powerful suite of tools and dedicated PHP libraries you can hook into. You can use ImageMagick via PHP for either file conversion or image manipulation, but the underlying tooling will need to be setup and configured on any servers you run your code on.
If you'd prefer to use commercial software with a dedicated developer support team to help you, and a powerful image rendering engine you could consider using the Zamzar API. With 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.
