6 Tips for Formatting Images for an eBook

Updated June 2017.

If a picture’s worth a thousand words, correctly formatted images for an eBook can be priceless!

We often get inquiries about image formatting, so here are a few tips to make sure the images you are using for your eBook are eReader ready.

1. Avoid wrapping text around images. Use in-line images with text above and below for best results.

2.Include that same text description of your picture below the image to make your images/pictures searchable.

3. Cover graphics should be at least 1400px wide, portrait or vertical rectangle-shaped artwork (no squares). We recommend a height/width ratio of 1.5 (1400px wide x 2100px tall). Your images should be 300 dpi/ppi (only in .jpg format).

4. Full-page images should be a minimum of 300 dpi/ppi, which equals a resolution of 600px wide x 800px tall on a letter-sized page. Logos or simple images: 75 – 100 pixels tall.

5. Don’t worry too much about the exact size of images within your document. The best approach is to size it how you want it to appear in relation to the text.

6. All images must be RGB only and 300 dpi (CMYK images are not accepted by our retail partners).

Other important tips of note when it comes to images are:

Image conversion

BookBaby can convert all of the graphic elements included in your eBook (and will convert up to 10 graphic elements for free on each eBook submission).

Images, tables, and diagrams

Images, tables, and diagrams require optimization to ensure proper display on the supported eReaders. Non-image materials such as excel tables, pie charts, and non-flattened artwork will be converted to jpegs for proper display on eReaders. These items will not scale or resize with the fonts.

Digital cameras pictures

When you take a photograph with a digital camera or scan an image using a digital scanner, the resulting file uses the RGB color mode so you will not need to convert these files.

Photoshop and color mode

If you are using Adobe Photoshop and want to check the color mode of your file, you can do so under Image > Mode. We suggest making any necessary color mode conversions from CMYK to RGB before you start color/tonal changes or photo manipulation.
