I need to change the dpi shown in the Properties of a printscreen jpeg image from 96 dpi to 300 dpi for text editing in Abbyy. How do I do this in Microsoft Paint or other freeware? I need to change the dpi shown in Properties, not just change the image size.
Almost any decent program can do this. But depending on which one you are using you need to "block" the file size.
I understand that Abbyy you are refering to is the OCR program. And somehow is a little "dumb" needing the file to declare that it is on 300 dpi.
If you are using windows try irfanview www.irfanview.com Then go to Image > Resize/Resample and do not touch anithing but the box where you define the ppi (actually it says DPI)
On any plataform use gimp www.gimp.org
Image > Scale Image and change the X and Y resolution. Simply do not touch the pixel values.
This two cases will simply change the little data embeded in the file.
- Neither of this will modify the image itself. but if you try to print it yes you totally are saying to the printer that the file will be much smaller, but only when printing. That ppi value is just an instruction for the printer.
I voted it down, because this question is basically just asking for us to tell you how to do something (a tutorial) and that's not what this site is built around. It's also something that can be found easily with a Google search.
That being said, here's your solution:
Download Adobe CC and take advantage of their free trial
Open the image in Photoshop and go to Image > Image Size
If you wish not to change the image's size, uncheck Resample
Change the resolution to whatever you want.
You can change the DPI of your jpeg image without an application using this free online tool:
- Enter your new DPI value
- Upload your image.
- Download the adjusted image.
