Reducing image file size: compress or resize?

For those who aren't sure of which solution to choose, we have you covered. Here are some explanations and tips to consider:

Compressing the image

Image compression is about minimizing the image file's size in bytes. It could be done via online tools or apps that you can download to your devices. However, there are some aspects that we need to discuss. Let's take a brief look at some other advantages of this method as well as some negative sides.

  • Size reduction

Image compression allows squeezing the image until it has the needed size. The image will take up less space while retaining the same physical size.

  • Slow devices

Some devices may load slowly when it comes to large uncompressed images. However, with image compression, your website can load faster as the smaller-sized images won't hold the drives to hold.

  • Quality degradation

When you compress an image, sometimes the quality of the image can decline. And it doesn't matter even if you save your new file in a GIF or PNG form. That's why compression isn't an advisable option in case you need high-resolution images with an extreme zoom-in function for your website.

  • Data loss

The compression may discard some of the image file's data. That's why you should always have an uncompressed copy in your sleeve in case you lose any needed file info.

Resizing image dimensions

Resizing the dimensions of your chosen image is a relatively simple option. It can ensure that your image quality remains to the needed requirements. However, the negative side of it is that it may be harder to ensure that the image file itself doesn’t pop up too big; consequently, rigging the speed of your website.

To resize image dimensions, you can use either online or software-based editing tools to do so. However, it’s important to know some essentials which you should keep in mind while utilizing this approach.

  • Choose correct picture

If your image has a lot of different things going on; it may be hard to choose how to resize it. Sometimes, you may need to cut out some parts. Also, trimming the dimensions down could make it hard to emphasize the image's details. That's why, when it comes to resizing, opt for a simpler picture with fewer details. For instance, images consisting of large areas, a single shade, and a narrow range of colors; also, ones with un-blurred areas.

  • Choose the right format

Each type of file format can perform better depending on what image you’re working with. Here are the top 3 used on the web:

  1. PNG is used for logos, illustrations, icons, and solid shapes.
  2. JPEG is the image file to use for photographs.
  3. GIF is an animated image that can only hold up to 256 colors which means that they need to be small and well-tailored so that you could convey your message.
  • Resizing your image

When you're done choosing your image and the correct format, you need to consider the size matter. The size of your image may differ regarding the place you want it to upload and the usage. That's why you need to determine what parameters the image needs to hold.

And most importantly, don’t forget to compress a file after you’re done fixing image dimensions. This will ensure that your new image won’t be hijacking your website’s speed.

If you're on Shopify, you can install an image resizer to make the process quicker

What is the best image size for websites?

The size of your image depends on the location you want to place it on a website.

The recommended file size for images is no more than 200 KB. For full-screen background images, focus on 1500 pixels but no more than 25000 pixel-wide. And for the rest, it's better to stick to a width of 800 pixels. Keeping your images within these frames will guarantee they load instantaneously on all screen devices.

Nonetheless, there is much more that could be said on this matter. Especially, if you’re running your website on Shopify, click and take a look at our guide on the image sizes.
