Photoshop CS2: TIFF to JPEG?

Larry H. - Atlanta, GA , Jun 08, 2006; 10:24 p.m.

Pardon me if this is a basic question, but I just cannot figure out how to do this without going through Zoombrowser. Hopefully, by asking this question, I will help someone else. So...

Is there any way to convert/save a TIFF file in Photoshop CS2 to a JPEG file? When I click on File/Save As, JPEG is not one of the options. Thanks in advance.

Chances are your TIFF is at 16 bits/channel. JPEG supports a maximum of 8 bits/channel. Go to the Image/Mode menu and convert to 8 bits, then save as JPEG.

File->Save for Web... gets you there, too.

You can also convert in batch from Adobe Bridge under Tools -> Photoshop -> Image Processor

Finally, opening the image in Imageready allows plenty of tweaks and conversion.

Each of these will let you create a .jpg copy without reducing the bit depth of your original file. (The jpeg copy will be only 8 bits / channel, however.)

ACDSee, for one, just highlight all the target tiffs, <ctrl> F (for format change, also available in the pulldwowns), pick your format, click ok.

It remembers your last options, for destination, & things like format settings (jpeg quality, for one. It'll also delete the targets on the fly, but this has to be selected each time.

Other viewers such as Irfanview are sim, I think.

And it doesn't come to an incomprehensible halt if the target is 16 bit: just converts it to 8 bit behind the scenes.

If you need a viewer anyway, I'd look into these cheap or free alternatives.

David sounds like he hit that one on the head.

You should be able to creat an action and batch the lot of them.

Thanks. David indeed figured out the problem: my TIFF files are 16 bit. But I like Chuck's solution better: using File/Save for Web. I will try the Bridge and ImageReady methods, too.

Typically, though, I am not looking to batch process to JPEGs as I capture images as both RAW and small/fine jpegs. I use the jpegs for slide shows to see which raw images I want to process, thereupon converting to 16 bit TIFFs. The conversions I needs are to create smaller images for the web or to give as proofs to clients.

Thanks to everyone, Larry

Larry, just be aware that when you use Photoshop Save For Web, this does strip the metadata from your images, so if you're concerned about someone trying to claim your images as their own, that's one less bit of proof you have on your side. That wouldn't stop a very determined thief anyway, but just thought I'd mention it in passing.

"Larry, just be aware that when you use Photoshop Save For Web, this does strip the metadata from your images..."

and imposes the limiting srgb colour space. so, i wouldn't do it for your keepers. i only save for web when i'm doing just that, saving it for the web or sending a copy off to the printer. i reccomend the same. otherwise i do it with image processor or while i happen to have the image open. in image processor you can select the same options as 'save for web' so perhaps get in the habbit of using it. it's fully automated too, just select any image in any format and run the processor and you're done.

What I use for jpg conversion is XNView, usually alot quicker than using photoshop. So I do all my TIFF manipulations, etc and then batch convert using XNView. it's a free utility and does a good job. At the same time, you can transform, and choose to change the DPI and size of the photos during the batch process. I find the less I have to do through photoshop, the less I want to throw my PC out the window :) - a great tool, but if even 2GB / 3.2Ghz runs sluggish with 16 bit tiffs loaded up on it.

In steps, I select all the tiffs I want to convert, transform - resize image down to 25% of size, change the DPI to 72 for viewing, and convert. Takes about 1 minute for about 10-20 tiffs on my computer.
