Optimizing your PDF for web before you publish it to Issuu will ensure the highest possible image quality and the most error free rendering of vector objects — in other words, the best presentation for your readers. Please take following points into consideration when preparing your content for exporting:
- Image PPI (pixels per inch) should be 300, both for color and grayscale images
- Complex vector objects must be simplified or flattened (as bitmap)
- InDesign effects such as drop-shadows, glow, special strokes, or transparency may not be fully supported
There are two ways of adding hyperlinks to your content:
- The easiest way is to use the Issuu Link Editor after you have published your content. Please see the help articles under Adding Links to my publication, for tips on how to use our Link Editor tool.
- You can also add hyperlinks using your favourite creation software (InDesign, QuarkExpress, etc), by including them directly in the working file
InDesign export settings

If you are using InDesign to create your content, you can download Issuu Export Preset and add it to your presets, to ensure during the export process that your PDF is Issuu-ready.
