I have an jpeg file of 300 dpi. I need to reduce it to 200dpi. How can I do that?

Do I need any specific application or it can be done using Picasa/paint/MS picture manager, if yes how? Thanks

Use Paint.NET

Go to Image > Resize > Change its resolution (dpi)

As I said the resolution in the Paint.NET is the DPI (pixel/inch)

I suggest using GIMP; it is a free image-editing solution, and it allows you to change the resolution, in pixels per inch, in both the x and y dimensions. I believe that this program can accomplish what you are looking for.

And I would take this one free tool:

To change DPI for the currently loaded image, click the "i" icon ("i" for information) on the IrfanView toolbar. Change the DPI, click OK, and save the image.

You can change the DPI of your jpeg image without an application using this free online tool:

1. Enter your new DPI value
2. Upload your image.
3. Download the adjusted image.

I think the best way of doing is this is software independent and without installation processes.

1. Google online DPI converter
2. Click First search. For me, the first hit is online-convert.com at the time, but their URLs are time variant so google for them: dpi online-convert
3. Select file to upload
4. Change the value of DPI only to 200
5. Done!

For resize an image I use Faststone Photo Resizer. It has an option for DPI.

• In advance settings you can choose all the settings: resolution, DPI, procentage. It's great.

I use Faststone Image Viewer . This allows you to set DPI in both X & Y dimensions using the Set DPI command from the Edit menu. This is a lossless change i.e. does not recompress the image.

Don't waste your time, images don't have a resolution (DPI) images are resolution independent

When printing tell the printer what size you wish to print the image and at what quality, then let the printer do the rest
