I have several hundred (690) lightoom files that I tried to export from Lightroom and I placed a 90MB size limit on them which was ignored by LR. Does anyone know of a simple way to do this? I don't want to resize them all in Photoshop if I can help it. Peter

There's no setting to limit file size when you export as TIF, so it wasn't "ignored by LR".
Why not do a few tests, see if they're near the 90mb limit and, if not, then just try doing the whole lot?
-
One of the options in the export module is file size, think that I might try them as Jpegs instead. Peter
-
Yes, it's an option that only appears when you choose JPEG.

I want to use these files for images on a website that i"m building called Photodeck and they store all the photos on a cloud drive. Will jpegs be OK because they will be opened and closed repeatedly and I don't want them to degrade in quality. Peter

Do you mean the files will be opened and saved or just opened and closed?
Closing a jpeg file doesn't degrade it, but saving (rewriting it) generally does.

Thanks Simon,

Tiffs are uncompressed image files. Therefore no way of reducing the file size in export from LR.
For web use, normally always use Jpegs. For normal web use, a maximum file size of, say 250Kb will be adequate and for some of smaller dimensions you may find that 30Kb is more than enough. To some extent it depends upon the range of colours and the amount of detail in the original file.
As has been mentioned above, simply opening and closing the web pages upon which the Jpegs appear does not, in any way, degrade the image quality.

How about, in the "export file", resize the image to smaller dimensions or resolution or both,in order to achieve the correct size in MBs ?

True in the sense you probably intend, although if you are concerned about file size you would want to be sure you are using tiff compression in the Lightroom output dialogue, which is lossless and may reduce the file size significantly.

Use PNG perhaps? Compressed, like JPGs, but lossless.
