Bluesky Image Sizes & Presets
Bluesky image handling is client-dependent and may change as the platform evolves. FastEdit keeps the presets conservative: 1000x1000 JPEG for post images, 400x400 PNG for avatars, and 1500x500 PNG for banners. These targets are practical for fast uploads while preserving predictable crops.
Pick this preset, drop your file, and FastEdit starts from the Bluesky Post Image dimensions, format, and file-size target.
Bluesky Image Size Cheat Sheet
Post Image
1000x1000 JPEG Max 1 MB
General-purpose post image preset for photos, art, and screenshots. Keeps uploads compact while preserving a square crop.
Open Bluesky Post Image preset →Avatar
400x400 PNG Max 1 MB
Profile picture displayed as a circle in the feed and on the profile page. Keep subjects centered.
Open Bluesky Avatar preset →Banner
1500x500 PNG Max 1 MB
Wide profile banner crop. Keep logos, faces, and text near the center because mobile and desktop clients crop the edges differently.
Open Bluesky Banner preset →Before you upload
- Bluesky currently processes uploaded images, so profile images and banners benefit from conservative dimensions and compression.
- Use 1:1 aspect ratio for the FastEdit post preset, or crop manually if your specific post needs landscape or portrait framing.
- Avatar images are displayed as circles: avoid placing important content near corners.
- Use JPEG for photos and PNG for screenshots, diagrams, and images with sharp text.
