Question

How do I resize this jpeg with Elements 12?

I have a 300 dpi jpeg, 3281 pixels on longest side, with file size of 21.7 MB. Need to resize to 72 dpi, no fewer than 1920 pixels on longest side and a maximum file size of 5 MB. How do I do this with Elements 12?

    Hello Michel,

    Thank you very much!

    I tried Solution A (Solution B is beyond my capability). I did what you said, setting the length (the longer dimension) to 1920 pixels. However, the total file size came to 7.43 MB, and it cannot exceed 5. Did I do something wrong?

    I hope you can offer a suggestion,

    Leslie

    You are right, I did not mention the resizing in MB.

    Once you have set your dimensions in pixels, the solution to get the correct size is to use the ability for jpeg files to 'compress' the size in kilobytes for the same amount of pixels. When you 'Save as' jpeg format, you can choose the 'quality level'.

    If you get 7 MB, you are probably saving in .psd format which is not compressed.

    You might save with the other file format: tiff with lossless compression to stay under 5MB.

    Another way not mentioned is to use File>Save for Web where you can resize and see the file size when saving as a Jpeg.

    Regular File>Save As>Jpeg might not differ in file size when changing compression settings if the file in question has lots of metadata.

    File>Save for Web removes all the metadata and while technically it doesn't set a resolution, since the metadata is removed, most applications/programs will read the resolution of the file as 72.

    Anyway, try File>Save for Web

    https://helpx.adobe.com/photoshop-elements/using/optimizing-images.html

    First though make sure your image is sRGB by going to Image>Mode>Convert to sSRG Profile.

    This insures your image will look as close to the way you see it on most peoples computers or devices.

    And check Embed Profile in the Save for Web dialog.

    When looking the file size in save for web, remember 1024 KB or K (kilobytes) = 1 megabyte.


    Many thanks, R_Kelly! Finally, success!!

    Two solutions:

    - A - First use the Image > Resize > Image size once without checking 'resample' and setting the dpi to 72

         Then use the same dialog again with all three options including resample checked, and set the width to 1920 pixels

    - B - Create a new empty document with the right size and dpi

         Then open the file to resize and move it from the photo bin to to the empty document, adjust the size with the move tool. When done, flatten and check the size.
