I have hundreds of slides that I have scanned to both .tif and .jpg files. The scanner defaults to the Adobe RGB color space. I had been keeping both the .tif and .jpg files in this space, but now I would like to convert the .jpg files to sRGB for sharing with others. Is there a way to convert these files in a batch process? Converting each one singly is becoming a boring pain. Any ideas?

I use NX studio to batch concert. Just select a file hold down the control key and select the rest. It will give you options for the conversion.

Can't really answer without knowing what software you have, or are you asking for suggestions on which software to buy to do this?

I have Photoshop Elements 2022 and Affinity Photo.

Hi Drbobcameraguy,
Thanks for the suggestion. I just downloaded NX Studio and tried the conversion, but it didn't appear to work. After setting the default to ICC sRGB and checking the box to convert to sRGB when saving a jpeg, I exported. When I then opened in Photoshop Elements it doesn't show that the profile is sRGB. Can you give me some detail on the process in NX Studio? Sounds like this will work if I get the correct process. Thanks.

There's a batch process under the File menu in PSE that probably can do the conversion.

Update - I only have PSE-10. I created some AdobeRGB JPEGs from RAW to JPEG via a LR Export. Then, I tried processing the images in batch via PSE. Alas, there's not option for the colorspace. I don't use the PSE cataloger. Maybe the Export process in the OP's PSE version does this, if the PSE export operates on a cataloged image?

Online, there's references to freeware from https://www.faststone.org/ or https://www.gimp.org/ for free software with the capability to run this batch conversion.

In the Adobe subscription, LR can perform this conversion via the LR export process. PhotoShop does this action via a Scripts / Image Processor action. My older PSE-10 doesn't have a Scripts capability. This might be different in newer PSE versions, or maybe is limited to the subscription PS software?

Affinity Photo will do it. Save one file as JPEG sRGB which will set the default to sRGB in the Batch mode. Then batch process. I tried it and it works well and fast.

My idea is to just share the files you have in Adobe RGB. I never have had a problem with anyone receiving and viewing my adobe RGB. I never convert to sRGB for image sharing even when asked to do it.

If you or the recipient are having prints made, then my recommendation is different. The colorspace of the image file has to meet the requirements of the printer.

If Your Scanner has saved 16Bit TIFFs as Adobe RGB and also saved JPEG's,which are 8 bit by default I am pretty sure the JPEGs be sRGB already. It may be possible to make ADOBE RGB Jpegs (still 8 bit) but I can't recall seeing that anywhere.
You should also check weather your TIFFs are 16 bit or 8 bit For the best archiving 16b Tiffs are usually recommended, JPEGs while great for many things, they use lossy compression.
If You have 16 Bit Tiffs in Adobe RGB, it might be easier to just keep those, and make Jpegs as needed.
Most Photo editing applications allow you to select any number of files and "EXPORT as JPEG" and even specify resolution & JPEG Quality

Thanks ecobin. I'll try that in Affinity.

Hi MJPerini,
Thanks for your input. The scanner outputs 8 bit TIFFs in Adobe RGB. I keep the TIFFs for printing after editing and saving as Adobe RGB since my printer (Canon Pixma Pro-10) can print a wider gamut than sRGB. I then save JPEGs for sharing because the file size is much smaller. Up until now I have saved the JPEGs as Adobe RGB, but now I want to convert them to a more universal color space. I keep the TIFFs as Adobe RGB. Going forward I plan to convert to sRGB before saving the JPEGs.

Batch processing in Affinity Photo worked fine. The only negative was that I could not set the quality for each individual file, but that was OK for my purpose. Thanks to all for your help.

Typically, in batch mode one setting for the entire batch is what's available. But you can set up several batches for different settings.
