To make your images stand out on social media, there are several key guidelines to follow. Here’s how to optimise your visuals for success.

The suggestions provided here are tailored for sharing images specifically through your Postglance account. Keep in mind that when posting via Postglance, the handling of images may differ from the native posting options on each social media platform.
Image Requirements, Formats, and Automatic Resizing
When uploading images to Postglance, files should be no larger than 10MB. Supported formats include JPG, PNG, and HEIC, with GIFs available for use on X/Twitter, Facebook, LinkedIn, Instagram, Mastodon, and Pinterest. Note that TikTok only accepts video formats.
It’s important to remember that each platform has its own image size limitations, which might differ from the limits imposed by native uploads. If your image is under 10MB but exceeds the platform's specific size restriction, Postglance will resize it while preserving the original aspect ratio.
Once you’ve uploaded your images, you can adjust their dimensions within the Postglance composer by following this guide: Editing Your Images in Postglance.
