These free photo resizers are perfect for resizing an image to fit nicely with websites like Facebook, Twitter, Google+, YouTube, and more. They're easy to use and you'll get your image resized in a matter of seconds without having to deal with a ton of other photo editing options.

Some of the resizers let you define the exact pixel width and height the new image should be while others provide preset sizes so you can literally resize with the click of the mouse. Some of these tools resize a picture by rescaling the whole image, and others are used to resize part of picture by use of a crop tool.

Whether you need to resize just one picture or resize dozens at the same time, you can find a photo resizer below that will get the job done. The best party of it is, all of these photo resizers will resize your image without placing a logo or watermark anywhere on the picture when you decide to save it.

Some of these websites also provide light image editing tools. However, if you need a more advanced or thorough editor, see my list of free online photo editors or free photo editing software. If you need a place to store your images, here's my review for the best free image hosting websites.

rsizr

Changing the size of an image at rsizr
rsizr

What We Like

  • Resizing to a specific pixel ratio.

  • Extra features like cropping and rotating.

  • Save the image to one of two formats.

What We Don't Like

  • Some tools are hard to use (no instructions).

  • Requires Flash — a known security vulnerability.

rsizr is an awesome photo resizer because it works in two ways. You can resize the entire image to a custom pixel size or you can crop out a particular portion of the picture to its own custom size. The picture can also be rotated.

When rescaling or cropping, the interface is very easy to use, letting you drag the crop tool around and resize the image by manually moving its corners.

When you're finished, you can save the image as a JPG or PNG file. You can also see the file size of the image before you download it, which can be helpful.

pixer.us

Resizing an image of water drops at pixer.us
pixer.us

What We Like

  • Real time, visual preview.

  • Very simple to use.

  • Editing options.

What We Don't Like

  • Only one image can be resized at once.

  • Can't enter custom dimensions.

pixer.us may be easier to use than some of the others in this list because you can visually see how big your picture is in real time as you resize it. However, while this is useful, pixer.us doesn’t provide the ability to manually enter the pixels, which means it can be hard to resize to the specific size you want.

You can also crop, rotate, and flip the picture. Other things like image effects and color manipulation tools are also available.

A picture can be saved as JPEG, GIF, PNG, or BMP.

Web Resizer

Changing the size of a photo at Web Resizer
Web Resizer

What We Like

  • Side-by-side preview.

  • Several editing options.

What We Don't Like

  • Too easy to not apply changes before download.

  • You can do too much too quickly and have to back out entirely to reset your work.

Like some of these other image resizers, Web Resizer shows a preview of your picture before you download it, which is certainly helpful. However, this website does so primarily because you can do slight editing to it, such as modifying the contrast and exposure.

Just enter the new width or height of the picture and click apply changes to refresh the preview. You can also rotate the image if you’d like.

You must apply the changes before the download link updates with any changes you make to the size of the picture.

The animation speed of the GIF can also be customized to anywhere from zero to 10,000 milliseconds.

Unfortunately, GIFMaker.me doesn't let you see a preview of the changes you've made. All you can do is download the GIF back to your computer.
