How to: Resize A JPEG | Step-by-Step Tutorial

Question

How do I adjust the resolution of an image in Paint?

Community Answer

At the bottom of the screen, you will see a section displaying numbers like "XXX x YYY PX," which indicates your current resolution. You can adjust this by dragging the small squares at the corners of the canvas; the resolution will increase or decrease as you resize. Simply adjust to your desired dimensions.

Question

When I open and save in paint, without doing image size reduction, the file size reduces by 50 percent. Does this cause a loss in resolution?

Community Answer

When you open and save a JPEG using Paint, the file is trans-coded so that Paint can read it. For example, if your image has 16bit encode for color, then it might reduce resolution by 50 percent.

Question

What is the difference between file size and image size?

Johnthan Fuentes

Community Answer

Image size refers to the image's height and width. File size refers to how much space the image takes up on your computer (or email inbox). For example, an image might size be 1920 pixels wide by 1080 pixels high, and the file size might be 2 MB.

Question

If I create a database with 2,000 images of different sizes, can I run the whole database through a resizing program and change every image to the same size, all in one go?

Johnthan Fuentes

Community Answer

Yes, some websites and programs let you resize batches of images. Try Picresize.com for a free option, or Adobe Photoshop for a paid program with lots of features.

Question

How do I set normal images to 64x64 pixel size?

Johnthan Fuentes

Community Answer

In most cases, the website or app you use to resize your image will allow you choose a height and width for your resized image. But since 64x64 is square-shaped, you may need to crop your photo into a square first so that the smaller, resized image doesn't look distorted.

Question

When I resize my image in Photoshop, I get a different overall file size than when I save it to the computer and check it. Which version is the one that must be under 5 mb? Compressed or not?

Johnthan Fuentes

Community Answer

The most accurate file size is the one on your computer. Photoshop will estimate the file size, but your computer will tell you the exact file size once you save the image. As for compression, an image with higher compression will take up less space than a one with lower compression (or no compression at all).

Question

How do you resize a jpeg without destroying the resolution?

Johnthan Fuentes

Community Answer

Making an image smaller will always decrease the resolution, since smaller images have fewer pixels. If you make the image larger, it might look blurry because there is no way to add resolution back to a small image. If you don't want to change the resolution, keep the image the same size and use minimal compression.

Question

When printing photos, some are too large for the 'Fit to frame' option, resulting in white edges even after selecting 'Borderless.' How can I resize my photos to fit the page without any borders?

Abdur Rahman Isty

Community Answer

You can use a web tool such as ProBatchResizer. This tool often has a 'fit container' option that will eliminate white borders when resizing images for printing.
