Storage Quota
Each organization has a storage limit based on their plan: 1 GB (Basic),5 GB (Standard), or 10 GB (Advanced). This quota is shared across all team members in the organization. You can track your current storage usage on the Uploads page.
When you reach the limit, you'll need to delete unused files before uploading new ones. Duplicate files are automatically detected — uploading the same file twice won't use additional storage.
Media Library
Use the Media Library to upload files once and reuse them across multiple posts and templates.

Media in Posts
Media files are attached directly to each post. When creating or editing a post, you can upload images and videos that will be published alongside your content.
Alt Text & Accessibility
Adding alt text (alternative text) to images improves accessibility and helps visually impaired users understand your content. PostRite supports alt text for:
- Twitter/X
Alt Text Best Practices
Describe what's in the image concisely. Avoid starting with "Image of..." - screen readers already announce it as an image.
Tips for Better Media
- High resolution: Use the highest quality source files
- Consistent branding: Maintain visual consistency across posts
- Mobile-first: Most users view on mobile - test how images look on smaller screens
- Text in images: Keep text minimal and large enough to read on mobile
- Video thumbnails: First frames matter - start with an engaging visual
- Compress videos: Use H.264 codec for best compatibility
Troubleshooting
Upload fails
- Check file size is within limits
- Verify file format is supported
- Try a different browser if issues persist
- Check your internet connection
Image looks different after posting
Platforms may crop or compress images. Use the recommended dimensions to ensure your content displays as intended.
Video won't process
- Ensure video is in MP4 format with H.264 codec
- Check duration meets platform requirements
- Try re-encoding with a tool like HandBrake
