Online Viewer guidelines, supported file types and fonts

Best practices and supported files and fonts when using the Online Viewer.

Viewer Guidelines and Best Practices

  • Ensure you are using a supported web browser and that it is up to date.
  • Avoid changing your computer network connection during a review.
  • Save often during your reviews (at least every hour).
  • Complete your reviews within a single browser tab. Avoid opening the same review in multiple browser tabs.
  • Use supported fonts in your PDF's. See below.

Up to 5MB of markups can be added each time you Save. If your markups exceed the 5MB limit when you click Save, you will receive a message to reduce the number of markups. If you intend to add large numbers of markups, we suggest adding them in batches and saving regularly.

Supported File Types

The online viewer currently supports PDF files for viewing and markup. 

There are high quality and/or free tools available for download that allow other file types registered on Aconex to be viewed on your desktop:

Supported Fonts

The Online Viewer supports an extensive range of generic fonts. If a certain font in your PDF is unsupported by the viewer, it will find the closest match from the supported fonts below, so you can still view the text, but with a slightly different font. When creating text in your PDF's we recommend using the supported fonts listed below:
