I have been taking pictures with my Sony A77 since 2011. I usually shoot sRGB. I have several thousand images that were taken using Adobe RGB colorspace. I've recently started using Lightroom. I use my JPEGs in other applications so I would like to convert these JPEG files to sRGB (I want to modify the existing file, not create a copy).
Can I/should I do the conversion within Lightroom?
If I need to use an external converter, will that make any difference within Lightroom?

The A77 uses an initial "_" in the file name to indicate Adobe RGB was used so I can identify the files. Once converted to sRGB I'll remove the "_". For the raw ARW files, I think I only need to remove the "_

Thanks for your help!

You will have to export to create a file using a different color profile. AdobeRGB is the larger envelop of colors for a JPEG. sRGB is a smaller set of colors that fits mostly inside AdobeRGB. Lightroom or any other program needs to rewrite the pixels to fit inside the colorspace that you choose. You really want to preserve the maximum range of colors possible and create a derivative image to fit the color capabilities. Older browsers and monitors were only capable of displaying the smaller envelope. It was develop by HP over 20 years ago. AdobeRGB was developed for printers that can display more colors. Some newer monitors also display colors in the range of AdobeRGB. Lightroom processes in the largest envelop ProPhotoRGB.

If you want to preserve the most colors available with your camera, you should shoot RAW and choose a colorspace suitable for your intended destination Print or web when you export. Here is a diagram that describes the differences in each colorspace

Thanks. I have a follow-up question but it is more of a workflow question so I'll post it as a new thread.
