This approach saves hours weekly while maintaining consistent presence across your social channels. By connecting your accounts once, you can focus entirely on content creation while PostOnce handles the distribution workflow behind the scenes.

Step 2: Create Your Automation Workflow — Once both accounts are connected, create a new crosspost workflow. Select Reddit as your source and Instagram as your destination. You'll see options for how to handle captions, hashtags, and media formatting. The defaults work great for most creators, but you can customize everything to match your brand voice. Learn more about crossposting from Reddit to Instagram.
Step 3: Set Your Distribution Rules — Choose whether to auto-post all content or use filters. Many creators start with "post everything" to test the workflow, then add hashtag filters to control what gets distributed. For example, use #crosspost to mark specific Reddit posts for Instagram distribution.
That's it! From now on, whenever you post to Reddit, PostOnce automatically handles uploading to Instagram. Your content is formatted properly, captions are adapted, and everything appears native to each platform. You've just saved yourself countless hours of manual posting.
Flexible Automation Options
Control exactly how your Reddit content gets distributed to Instagram with powerful automation rules.
Post Everything
Every Reddit post automatically goes to Instagram
Filter by Hashtag
Use specific hashtags to control what gets crossposted
Custom Rules
Set advanced filters based on your workflow needs
Most creators use hashtag filtering to maintain control over their crossposting workflow. For instance, you might want all your Reddit tutorials to go to Instagram, but keep personal content separate. Simply add a specific hashtag like #autopost to your Reddit caption, and only those posts will be distributed.
If you want to repurpose content from Reddit to Instagram, you can also customize how captions, formats, and media are adapted for each platform's unique audience and requirements.
Automatic Content Optimization for Instagram
Your content doesn't just get copied—it gets optimized for Instagram's format, audience, and best practices.
Media Format Adaptation
Videos are automatically converted to Instagram's preferred aspect ratios and resolution. Whether Instagram prefers vertical, square, or landscape content, your media is optimized without any manual editing.
Caption Optimization
Captions are adapted to fit Instagram's character limits and style conventions. Hashtags, mentions, and links are formatted correctly for each platform's requirements.
Native Appearance
Your Instagram posts look like they were created directly on the platform—not like automated reposts. This maintains authenticity and engagement with your audience.
Timing Intelligence
Content is published to Instagram at optimal times based on your audience's activity patterns, maximizing reach and engagement automatically.
The goal is simple: your content should look native to every platform, not like it was bulk-uploaded. PostOnce handles all the technical optimization so your Instagram audience gets the best possible experience.
