The thumbnail generator is designed to create thumbnail images for many types of files uploaded to the site. It works well for many files, but isn’t the best option in some cases. If you're dissatisfied with the images produced by the generator, you can opt to upload your own thumbnails instead.
One good way to make your own thumbnails instead of having TpT generate them for you is to take a screenshot, following the steps below:
- Open the file you’d like to showcase.
- Zoom out of each page so that it's small but still legible.
- Take a screenshot of each page. This site contains information on how to take a screenshot: https://www.take-a-screenshot.org/
The recommended image dimension is at least 750 pixels and the file size should be smaller than 2MB. If your files are too large, zoom out farther when you take your screenshot.
When you’re creating a new listing or editing a current listing, choose the “Upload your own thumbnail images” option to upload your screenshots.
