Simple question: How to retain file size after just rotating image
I use IrfanView to open a 1265KB jpg file and rotate the image 90
degrees. If I save it with best quality (100 under JPEG/GIF save options), the file size becomes 2086KB. I don't want to over- or under- sample the image. All I need is to rotate the image because the picture was taken sideways. How can I keep the file as is including resolution after the rotation? Thanks. Yong Huang yong321 at yahoo.com |

Thanks. Shift-J does lossless jpeg rotating for my version. No saving involved. It's in the Options drop-down. |

The new file after image rotation is slightly smaller though, for instance, 4,750 vs the original 4,989 bytes, 334,353 vs 346,081 bytes. But that's good enough. Yong Huang |
