Four Cool (free) Tools to Enhance, Enlarge, and Improve Your Images

Created On: 6/23/2022

Our customers often ask us to enhance, resize, convert, or help them find the correct print size for their image to ensure the best quality prints. So, we decided to build four free tools to make our customer's images pop when they are printed. Read below for more information on how our tools can help you get the best picture for your printing projects.

Image Aspect Ratio Calculator

Do you have an image you want to print but are unsure about the best print size to choose for your pic? Our Image Aspect Ratio Calculator is the tool you need!

You upload your image, and our aspect ratio calculator will find the best print size. It doesn't get easier than that!

You can select an image on your computer, tablet, or phone, and the calculator will determine the sizes that best match your image.

But that's not all! You can also crop, add black bars, or sometimes stretch an image to make your picture fit different print sizes. This is particularly handy when you have a frame size you want to match

If you have problems getting the image just right, you can contact our customer service for help.

Image Size Finder

Do you have an image you want to print but are unsure of the size? We have a tool for that! Our Image Size Finder is beneficial when you need to find your pic size, especially on mobile devices.

Upload your pic to our Image Size Finder and poof! You get the height and width of your image in pixels. Pretty cool, huh?

In our guide on image size, you can learn more about choosing the right image size for printing a poster, canvas, decal, etc.

Image Converter

Our customers often asked us to convert images to different formats, so we decided to build a free tool to easily convert images from one file format to another. We made a free online image converter tool so that customers and future customers have an easy-to-use, self-service tool to change file formats.


The PosterBurner Image Converter lets you easily convert your image from one format to another. For example, if you want to convert a pdf to jpg, you can upload your pdf file and select jpg as the "to file type," and voila' your image is converted to the file type you need.

If you need to improve your converted file, you can Enhance your image with our Super Resolution tool.

Please note that there is a size limit of 20MB or smaller.

Enhance Super-Resolution to Improve Image Quality

PosterBurner Super-Resolution is a free tool to improve your image quality and enlarge your image. Artificial intelligence smartly paints each pixel as the image size is enlarged. Our Super Rez tool works well on images 2000 x 2000 pixels and below.

Images between 500 x 500 and 2000 x 2000 pixels before running super resolution print beautifully.

Check out our guide on image size and printing size, or you can send us your image at and we'll help you find the best size for your image.

Holiday Shipping

Holiday Shipping Times & Cut Off We are currently able to ship all print types in time for the holidays, but the sooner you order, the better. Shipping companies are advising to ship packages for holiday delivery by December 16th. Many packages shipped after the 16th will still arrive in time for the holidays, but they are not guaranteeing it. While we do not have full control over the shipping and transit times, here is our best guess at the realistic cutoff dates. West Coast: Order by December 16th Central: Order By December 20th East Coast: Order by December 21st
