FAQ

Q: What happens to images larger than 5MB or 2000×2000px?

A: Images are automatically resized and compressed during upload to meet Bluesky's requirements. Images are processed to stay within 5MB and 2000×2000px limits while maintaining the best possible quality.

Q: Can I edit images after uploading?

A: No, you cannot edit images after uploading. You can only delete and re-upload them.

Q: Are animated GIFs supported?

A: No, GIF format (including animated GIFs) is not supported. Please use JPEG, PNG, or WebP formats instead.

Q: Can I upload photos taken with my smartphone as is?

A: Yes, absolutely! The system is designed to automatically resize and compress large photos to meet Bluesky's requirements. For very large files (e.g., close to 50MB), pre-processing might speed up the upload, but it is not required.
