Just these five simple steps will get your documents ready to become great digital publications.

Check file type

You already know that digital publishing with Calaméo can help you go beyond the PDF. However, our powerful conversion technology handles many different file types. In addition to PDFs, you can upload text files, Word documents, Powerpoints and Excel files directly to Calaméo. Before you publish, take a moment to make sure that your document is in one our accepted file formats.

Reduce file size

When you work with high-quality images, complex layouts and other data-rich elements, the size of your file sometimes grows quickly. Since BASIC and PREMIUM users can convert files of up to 100 MB on Calaméo, it may be necessary to reduce your file size before upload. Don’t want to worry about limits? Upgrade to PLATINUM and start publishing with a maximum file size of 500 MB.

Format links

Our easy-to-use Editor is a great tool for transforming your documents into interactive digital publications with GIFs, video, audio and more. If you have external links to include in your publication, you can also take advantage of automatic link detection on Calaméo! All you need to do is add the site URL in a clickable zone on your PDF. Once your file is converted, a link will automatically appear in your publication.

Print to PDF 

Most importantly, every part of your document should always look impeccable online. To ensure a flawless conversion on our platform, try printing your file to PDF rather than exporting to PDF. (We especially recommend this for Word documents with images, tables and other layout features.) As well as preventing display errors, you’ll also benefit from a reduced file size by printing to PDF.

Prepare images

Our cutting-edge conversion technology offers vibrant, clear images for publications that are works of art. But for those times that you need ultra-high resolution, consider adding image files to your publication with our Editor. First, make sure that your file (.JPG or .PNG) is hosted securely online. Next, leave a blank space in your original document where you wish to place the image. Finally, insert your image and save. You’ll enjoy perfect quality, even at the highest levels of zoom.
