How do change the default "Save As" from PSD to JPG?

Hey Guys, I have a question if you don't mind . . . .  Once I've completed editing a picture, I select "Save As" and give it a different name from the original. When I open the original file to perform a different edit, the file opens in Camera Raw as the "Save As" file. How can I prevent this ? Thanks.

I have the same issue.  Have been super annoyed by the lack of helpful answers.  I DID, however, notice that the CROP tool is likely to blame in my circumstance.  I was so frustrated because I have decades of experience with Photoshop. Opening a JPG file, cropping and adjusting it, creating NO new layers, should default save as JPG.  But mine was asking every time to save as PSD. I just noticed after reading a few of these replies that my crop tool is creating a layer by default, thus eliminating JPG as a natural default.  Looking into my crop tool now.  I've never seen the crop tool do this by default before. That's why I didn't even check whether my image was layered, having always made the decision to deliberately make layers before. I hope I can figure out how to get the crop tool to knock it off. It may be the answer for some others with this problem.

Okay so I prefer to save as PNG (just my preference) But what i found to work (not 100% sure how) But if i hit cntrl+shift+S it defaults to PSD file (super annoying) However When i Hit cntrl+Alt+S It defaults to PNG. (no idea how i did this, maybe its because i save as png all the time and that command is for most used saved format) But i figured give cntrl+Alt+S (or w.e is equivalent on mac) a try.
One note tho: Every now and then it will try to save as a psd and i just cancel and hit the command again and it is png (maybe it will be jpeg for you). Really hope this helped

When this happens to me, it is because I have clicked on the quick mask mode.  As soon as it is unchecked, I can save normally.

file-export-qick export as jpeg. (only CC2015).

I did "hotkey" for it, noe it`s easy)

The easy answer is when you hit Save As, where it says Format, change jpg to psd, or vice versa.  It will stay that way until you make a change in the future--i.e. always jpg or always psd (or tiff or whatever you choose from the drop down list).  I always save a psd file first, so that I have all the work I've done but with all the original pixels saved forever.  Then, I save that to a jpg file.  

Here is an interesting and very useful shortcut.  Let's say you want to save a lot of images to jpg. Rather than doing them one by one, first highlight all the images you want to convert (they can be in their original form or in psd).   Then, while you are open in Bridge, you go to Tools, Photoshop, and then Image Processor.   It will ask you where you want your new jpegs saved.   You can name a folder that you have already made, or you can say your desktop, or you can say in the same place.  If it saves them in the same place, there will be a new jpeg folder at the end of the folder you are working in, and it will contain the new jpegs.   Then you put in the quality (12 is best, 7 is good for emails), and hit Run.   It will save the whole batch one at a time in a few seconds.  

(first of all: sorry for my poore English)///

I spent half of a day to find possibility to quick save as Jpeg, and find out - it is not easy to do in old versions...

But in CC 2015  it is easy: file-export-qick export as jpeg.

Expanding on this question, is an option available in Photoshop to automatically save a PSD version when a jpg, png, etc. is saved? And when the jpg is opened, the layered PSD version is instead opened?

In Photoline it is optional to save a native PL version when a JPG is saved. So even if the default save format is changed to JPG or PNG, there is no chance of losing the original layered file. When the JPG is opened in Photoline, Photoline automatically detects that a PLD "sidecar" version is available, and opens that one instead. Edit the file, and save: the JPG is updated, as well as the PLD.

I found this simple option to be extremely useful. I tried searching for a similar option in Photohop, but I believe it is not possible? Well, I suppose we could create an action which saves a document both as a PSD and a JPG. But opening the JPG in Photoshop will still ignore the PSD version, correct?

My workaround is to use the File > Process Multiple Files. Leave everything unchecked except "Convert files to . . ."

If I need to rename each photo something specific, I process one at a time.

The only downside to this is your original will disappear -- including a .psd you've been working on, so make sure the original is saved first.

I found a helpful script on superuser.com:

How to select png format as default for save in Photoshop CS5 - Super User.

It is for changing the default Save-As to png, but can easily be adapted to Save-As a jpg.  Here's the script:

try {main(); } catch(e){}

function main(){

    activeDocument.saveAs(app.activeDocument.path, SaveDocumentType.JPG, false, Extension.LOWERCASE);

}

Note:  This script will automatically save the file in its original folder.  If you want it to save your file to a different folder, replace app.activeDocument.path with the specific path where you want to save to.

If you're like I was and hadn't ever created scripts for Photoshop before, here's what I learned and the steps I used (CS5):

1. Copy the script above and paste it into a plain text editor.  (I used Notepad.)
2. Save it as a .jsx file. 
   (In Notepad, for the Save as Type, select "All Files (*.*).  Then, for the filename, type in the filename you want to use with a .jsx extension.  I used "Save As Jpg.jsx")
3. Move yourscriptname.jsx to the Scripts folder.
   (On my Windows 7 computer, this was C:\Program Files\Adobe\Adobe Photoshop CS5 (64 Bit)\Presets\Scripts)
4. Open Photoshop  (If it's already open, close and reopen it.)
5. Assign a shortcut key to this script:
   1. Go to Edit > Keyboard Shortcuts > Application Menus > File > Scripts > yoursriptname
   2. Press the keys you want to use for your shortcut.  (I used SHIFT+CTRL+S)
   3. Click Accept, then click Okay.
6. Whenever you want to save a file as a jpg, just use your shortcut keys (SHIFT+CTRL+S)
   or, go to File > Scripts > yourscriptname.
