Bluesky Image Sizes & Presets
Bluesky accepts images up to 2000x2000 pixels for posts and 1000x1000 for avatars. As a newer platform, its image specs are simpler than older social networks, but getting dimensions right still matters for sharp display in the feed. FastEdit resizes your images to Bluesky's recommended dimensions with one click.
Presets
Post Image
2000x2000 JPEG / PNG Max 1 MB
Maximum resolution for post images. Images are displayed at various aspect ratios in the feed. 16:9 landscape and 1:1 square work well.
Avatar
1000x1000 JPEG / PNG Max 1 MB
Profile picture displayed as a circle in the feed and on the profile page. Keep subjects centered.
Tips
- Bluesky compresses images to under 1 MB on upload: pre-optimizing in FastEdit gives you control over the compression quality.
- Use 16:9 aspect ratio (e.g., 2000x1125) for post images that display well in the feed without cropping.
- Avatar images are displayed as circles: avoid placing important content near corners.
