how do you convert an image to 300 dpi with photoshop ?

Question

I'm making some flyers and the printing people said the jpeg image needs to be 300 dpi, I have no idea how to do it. Any help? Thanks.

Answer 1

This is the step-by-step method on my old ancient version 4.0. Hopefully, it's the same for your version. I'm assuming you know nothing so forgive me if it's a bit oversimplified. Also, step #4 in this method will prevent the problem discussed in the previous reply about reducing the sharpeness or crispness of the photo.

1. From the menu at the top of the window, select "File", then select "Open".
2. Find the jpeg photo file on your hard drive or in your camera and click on it. Then click on "Open".
3. From the menu at the top of the window, select "Image", then select "Image Size".
4. In the bottom left-hand corner of the Image Size window, click off the checkmark in front of "Resample Image".
5. Change the "Resolution" (which is probably set to 72) to 300.
6. Click on "Ok".
7. Then from the top menu again, select "File", then select "Save a Copy".
8. Name the new photo whatever you wish and click on "Save". You may have to do this twice (some versions).
9. Select the quality you want the photo to be saved at. In most cases, you can just leave it at the quality that Photoshop recommends. Or if the filesize doesn't matter to you and you want the best possible quality, choose the highest quality level.
10. Click "OK" and your photo is now on your hard drive at 300 dpi with no loss of pixels!

Good Luck!

Open your image in photoshop, then go to Image - Image Size. That will open a window where it shows you picture's size. Look ate what it says under "resolution." If it's 150 dpi or 72 dpi or any other number below 300, you can manually change it to 300 (just type in 300 in that window) and that will stretch your picture to a high-resolution image. However, it is not going to look "crisp" and sharp anymore, since the program has to fill in those "missing" pixels on its own (pretty much make those up).
See if that helps.

Printing people would use the term DPI just to confuse you! DPI really stands for Dots Per Inch. That makes sense when you are talking about printers putting so many dots per inch to create a picture. What they mean is you need to change the resolution, so that's what Photoshop will call it. Go to the Image Menu > Click on Image Size. On that window you should be able to change the Resolution to 300. That should be all there is to it. See the supplied link for a little more info.

If I can assume you are using photoshop cs, first pull down the file menu and open the desired file. Next using the image pull down menu open "image size" in this pop up screen uncheck constrain proportions, then change resolution to 300, the default should be 72. You may also want to change the actual image size in this menu. Hope this helps.

You can use the crop tool if you know what dimensions your pic should be. Click on the crop tool, and in the top bar you can set the dimensions you want and the resolution (this is where you want 300 pixels/inch). You should be down-sizing the image to your final size for best results - but small up-sizing may be good-enough quality in some cases. Downsizing reduces the total pixels in your image - potentially making it sharper. Upsizing adds pixels - PS guesses where it can expand the image, and can make your image blotchy and/or fuzzy.
