# GVM Link vs 图片格式转换

The clearest difference is in-app purchases: GVM Link at none against 图片格式转换's 1. GVM Link also leads on device support (3 vs 1) and iOS requirement (12.0 vs 16.6). On price and ads there is nothing between them.

Both are free to download. 图片格式转换 sells 1 one-off in-app purchase. GVM Link asks for nothing beyond the download.
