I tried that, but it causes the Resolution to change...
Need to reduce Document width, while also keeping resolution at 72 dpi and Pixel width at 1920.
If ppi and pixel width remain the same, you haven't changed anything. That's like saying I want letter-sized paper (8-1/5" x 11") but I need it to be smaller.
One of the two must change to make the document "smaller."
I'm trying to reduce the file size. It is 2 MB and needs to be under 1.8.
Also need to keep at 72 dpi and 1920 pixels. Any way to do this other than
making the document size smaller? Can't seem to do so without changing one
or other dimensions...
OK, what you need is compression, which reduces file size, not document size.
Save the file as a jpeg.
But remember that jpeg is a "lossy" format. Start with the highest possible quality (12), and only reduce the quality setting if your file isn't small enough.
Also keep the original Photoshop file for future use, since jpeg is a lossy format.
Got it. Thanks!
2Mb is huge for a JPG of 1920 pixels wide. Every single pixel would have to be wildly different from the pixels around it for the compression to produce such a large file.
On the other hand, 1920 pixels wide is OK for a screen saver or online slide show, but small for a photograph. I wonder how it is being used?
