I need a way to resize my images or a setting to convert my images or png's into anything above 300ppi, how can I do this, I have all adobes, thanks!

How many ppi are they now?

Use Photoshop or Lightroom.

Image ⇒ Image Size 

Change Resolution to the required value.

See more details below.

Effective PPI is only in InDesign, as far as I know. The way to increase the Pixels Per Inch in InDesign is to scale the image smaller. The Links panel will tell you both the actual PPI and the effective PPI. 

Are you using InDesign?

You're correct that Photoshop doesn't use this as an explicit terminology, however, simply resizing the image using Image > Image Size with the Resample checkbox off/inactive does the same thing (changes the print size without affecting the source pixel count). Photoshop's actual resolution will equal the effective resolution when placed at 100% scale in InDesign.

True, Stephen.

We don't know where @danika_0115 originally posted or which application she is using. All we know is that she was asked which application, then her post was moved to Photoshop without her answer. "Effective resolution" was her terminology and we need to find out what she is using to give her the best answer.

@jane-e - agreed, you are correct, my guess would be InDesign, but as you say, it's just a guess.

@danika_0115 - If you're out there, please explain your issue in more detail, including the app in question.

In addition to opening/resaving each image and resizing the image in Photoshop using Image > Image Size with the Resample checkbox off/inactive there is another approach, which is to edit the resolution PPI metadata directly via a script (better for JPEG to avoid lossy decompression/recompression):

Photoshop version:

Bridge version:

Note: Due to limitations in metadata and scripting, this is NOT for PNG images. For PNG images, one would use ExifTool to change the specific PNG Pixels Per Metre value:
