Why are some of the images in my Webflow code output being renamed with additional characters?

When you upload images to Webflow, the system automatically renames them to ensure that the file names are unique and do not conflict with existing files on the server. This is done as a precautionary measure to prevent any potential issues related to caching, servers, or compatibility.

The additional characters that are added to the file names are a combination of random numbers and letters. This helps create unique file names that are not easily predictable or prone to clashes with other files in the system.

Here are a few reasons why Webflow adds additional characters to image file names:

  1. Conflict prevention: By adding random characters to file names, Webflow minimizes the chances of file name clashes, especially if multiple users are uploading images with similar names at the same time.

  2. Server compatibility: Some servers have restrictions on file names, such as limitations on length, special characters, or file extensions. By adding additional characters, Webflow ensures that uploaded images meet these server requirements.

  3. Cache control: When images are modified or replaced on a website, caches need to be refreshed to display the updated versions. Changing the file name provides a way to bypass outdated cache entries and ensure that the latest image is loaded.

  4. SEO optimization: Adding unique characters to image file names can help search engines index and differentiate images more effectively. It can also prevent images from being mistakenly associated with unrelated content bearing similar file names.

If you wish to retain the original file names without the additional characters, you can manually rename the images before uploading them to Webflow. However, keep in mind the potential risks of file name conflicts or compatibility issues that may arise in such cases.

Remember to optimize your image file names for SEO by using descriptive and relevant keywords. This can aid search engines in better understanding the context of the images and improve your website's overall visibility.
