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.

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

Using JPG with PHP
You have a number of options when looking to convert JPG files using PHP and each of them have various pros and cons. You could consider using the GD PHP library which has quite extensive support for image processing and has a large number of online resources which you can use as a great reference guide when writing your code.
Another option is to use an open source tool such as ImageMagick, which is known as the "Swiss Army Knife" of image processing. It has a large number of configurable options and is fairly easily configurable through a handy object-oriented interface - see these examples. It also has extensive documentation and there is a wide body of online support in forums should you hit technical issues.
