What’s the best image size to upload?

Glass works best with JPEG or PNG exports that keep your EXIF and an embedded color profile (sRGB or P3).

On the web, upload JPEG or PNG and keep files under 50 MB. On iPhone and iPad, you can choose photos from your library.

Aspect ratio limits:

• Landscape: up to 3:1
• Portrait: up to 9:16

Glass keeps your original upload and creates optimized display copies (up to 3072 pixels on the longest dimension) for other members. See Sharing your work and Image quality.
