PDF Converter Online

Muhimbi’s products are trusted by thousands of high-profile organisations.

Comprehensive API

The Muhimbi PDF Converter comes with a comprehensive SOAP Based API, compatible with most modern languages and environments including Java, C# and PHP. The platform itself run on Windows Server, but it can be accessed from any platform including Linux, MacOS and mobile devices.

The API exposes a rich object model which can be used to convert, split, merge, watermark, secure, OCR* and archive* most common file types. It is extremely robust and scales both up and out.

Plenty of sample code is available for the various platforms, backed by our amazing support desk. A separate Online SaaS version of this product is available here.

Convert and transform files

A typical office environment uses a lot of different file types including Word, Excel, PowerPoint, Email, InfoPath, AutoCAD, Visio, Images and HTML. There is no ‘one-size-fits-all’, though PDF comes close.

Muhimbi’s platform supports all these formats and more. Not only are documents converted with perfect conversion fidelity, we go the extra mile to make sure that files attached to InfoPath forms and emails are processed as well.

Automatically re-colour AutoCAD files, no problem! Control which InfoPath views to convert, even easier. We even allow full control over MS-Word’s change tracking facility.

Watermark PDF, Word, Excel & PowerPoint files

The platform comes with very extensive watermarking facilities which allow documents to be 'stamped' with all kinds of information, including text, barcodes, images and QR codes.

Muhimbi is unique as it not only allows watermarks to be added to PDF Files, it can even watermark Word, Excel and PowerPoint files.

Watermarks are used for a myriad of reasons including embedding metadata, protecting intellectual property, showing the security level (Top Secret, Confidential), and facilitate track & trace using barcodes.

Naturally we take it to the max and – document format permitting – we make it possible to only display watermarks when the document is sent to the printer.

No watermarking system is complete without the ability to secure and encrypt the content, which is why Muhimbi supports various mechanisms for adding passwords and restrictions to documents.

It's much more than just a PDF Converter


Convert common file types including Word, Excel, PowerPoint, Emails, InfoPath, AutoCAD, Visio, Images and HTML with perfect conversion fidelity.


Combine multiple files into a single, easy to manage and easy to share PDF. Automatically add PDF bookmarks and a Table Of Content for easy navigation.

SharePoint Page to PDF

Convert and archive SharePoint pages such as lists, list items and wiki pages to PDF. Pass in custom HTML to easily generate reports and other content.


Dealing with large and unwieldy files? Make them more manageable by splitting them into multiple smaller ones based on the number of pages or PDF bookmark level.


Dealing with sensitive data or need to include the latest metadata in your PDF or Office documents? We've got you covered with our flexible watermark engine.


Dealing with scanned or faxed content? Your search engine won't be able to find these files, so use Optical Character Recognition to make your documents discoverable.


It is not just about conversion to PDF. If you need to convert between other file formats (e.g DOC to DOCX, XLSX to DOC, or InfoPath to DOCX / XLSX), it's perfectly possible as well.


Most organisations and regulatory bodies publish retention guidelines for data. The PDF Converter can assist by generating PDF/A1b, A2b and A3b files.

Secure & Restrict

Sharing documents is easy, but what if the information is sensitive? Muhimbi makes it easy to encrypt PDF and Office files, or restrict the ability to print and copy content.


Applying watermarks and PDF restrictions without encryption is meaningless when a simple PDF editor is only one Google search away. Use our software to encrypt your PDFs.

Forms Data

Still copying and pasting data from PDF files by hand? Automate PDF Forms processing by importing and exporting forms data using your favourite platform or language.


Processing documents manually is great, but automatically carrying out various tasks via workflows or API is where our product really shines. No room for user error!

Muhimbi has a 4.5+ rating in Trustpilot and App Store.
