Posting from Your Phone
Step 1: Tap the “+” icon on the Home screen.
Tap the center “+” button to begin a new post.
Step 2: Choose media.
Select an image or video from your camera roll, or hit the camera icon to capture a new one. Use the “↔︎” button on the left to crop to 1:1, 4:5, or 16:9 as you prefer.
Select a photo and adjust its aspect ratio.
Step 3: Trim and edit.
If you selected a video, slide the trim bar to set the length, then choose a cover frame or upload a custom thumbnail. Apply a preset filter or tap Edit to tweak brightness, contrast, saturation, hue, vignette, and more.
Trim video and add a cover image.
Step 4: Add details.
Craft a compelling caption, sprinkle relevant hashtags, and tag people or businesses. Include a location to give context. Use the Advanced Settings menu to hide like counts, disable comments, or add ALT text for accessibility and SEO.
