Image Resolution Checker: Is Your File Big Enough?

What image resolution means

Resolution is the number of pixels in the image: width x height. A 6000 x 4000 photo has 24 million pixels, so 24 megapixels. That count decides how much detail the file holds and how big it can print.

The DPI number saved in a file does not change the resolution. It only says how many pixels go into one printed inch. To read it, use the DPI checker.

Minimum resolution by platform

Shutterstock's own example: 2000 x 2400 pixels is 4.8 megapixels and passes, 1200 x 3000 is 3.6 megapixels and fails.

What to do when the image is too small

• Make it bigger at the source. Export the full-size file, or generate AI images at the biggest size the model offers.
• A 1024 x 1024 AI image is about 1 megapixel. It needs a 2x upscale to clear the 4 megapixel floor of the stock sites. Our Magnific upscaler teardown shows what that costs.
• Be careful with Displate. It rejects files that were resized only to reach 2900 px, and it can block accounts that do it again and again.
• For a print, work out the pixels you need with the DPI calculator.

Once the file passes, the next step is the title and keywords. Our guides on Adobe Stock rejection reasons and how to sell digital art cover what comes after the upload.
