Image resizing tools for your author photo

You've been asked to provide your author photo in a particular file size and dimensions. Or you want to shrink an image, or a set of images, to use for the web. There's no need to hire it out or use photo editing apps. These online tools will do it for you, for free in just a few time and money saving steps.

The standard resolution for web images is 72 dpi, so if you have a 300 dpi image that's great for print, keep it, and shrink a version to 72 dpi. The tools below will help you do that.


But what dimensions should your author photo be? Some organizations want your author photo to be a certain length on one side. Others want square images. 

The first photo has the typical dimensions for a portrait.

The one under it is square, and is preferred by website designers who display headshots in a a circle shape.


If you'd like to edit your photo for style, brightness, or color, use the Pixlr freemium editor before you shrink it. This editor has a lot of great features. Especially check out the glamour and vignette filters. Once you get in there you'll see you can waste a half a day playing with these as I did with liquify (add waves to your hair!), posterize and fringe.

Resizing tools

  • Google Squoosh browser app is the simplest way to reduce the compress and resize an image that already has the dimensions you want.
  • ImageResizer lets you resize, crop, flip, and rotate.  
  • Img2Go resizes and includes a bunch of cool frames and corners, stickers, filters, arrows, shapes, text blocks and backgrounds., 
  • BulkResizePhotos does exactly that for a batch of images to change exact dimensions, width, height, scale, or shrink to longest side. 
  • PicResize resizes and has a lot of special effects including rounded corners, frames, and effects like polaroid, grayscale, sharpen, and oil paint.
  • ResizeImage lets you crop, rotate, resize, optimize, compress, and change the output format of your image. 

You can go overboard playing with some of these editors. (This was done with Pixlr.)

And, for social media...

The social media platforms seem to change the optimal size for their profile and site images all the time. Luckily, Louise Meyers keeps up with all this: Check out her Social Media Cheat Sheet 2020: Must Have Image Sizes!

I'm sure there are more free and freemium editors that do this kind of thing. Do you have a recommendation? Please let me know in the comments below.
