Optimising Product Images: Best Practices For Online Sellers


When it comes to your product images, it could be something that helps you seal the deal. “How so?”, you may ask. This is because your images are visual representations of your products and significantly influence purchase decisions.

However, simply having images of your products isn't enough. To maximize the impact of your images, it's essential to optimize them for your online store.

Why do you need to optimize your product images?

Product images are crucial to the success of any online store as it adds to the overall design of your store, help your customers make better purchase decisions when they view your images, and also help improve your site’s SEO ranking. 

An example will be the file size of your image. Having too large an image size can slow down the loading speed of your site, affecting not only the search engine rankings but also the customer experience.

How to optimize your product images?


In this age of high-speed and high-resolution internet, it's still important to prioritize image optimization. With modern technology, it's easy to capture high-quality images using cameras or even smartphones, which you may have used for your online store. 

However, using large images on the internet can slow down loading times, especially on mobile devices, which can lead to frustration and increased bounce rates. To avoid losing potential customers, it's crucial to reduce the size of your images for optimal web performance.

An image has two sizes that you should be aware of, the first being the image size, which is measured in pixels. For SHOPLINE store, we recommend a minimum image size of 560px for the width and 840px for the height. The other is the file size which is the memory space that the image takes up. This size is measured in bytes, typical Kilo- (Kb), Mega- (Mb), and Gigabytes (Gb). For SHOPLINE store, you can upload product images of any size up to 10 MB.

Proportion or the ratio of an image is important as well. Some ratios are more pleasing to look at and enhance the visual experience of a customer when shopping with you. 

Here is an example of the standard ratios used. (source: https://phlearn.com/magazine/how-to-know-which-aspect-ratio-to-use-in-your-photography/)

Aim to maintain consistent proportions across all your product images to create a cohesive and polished appearance for your store.

Selecting the right image format:

When it comes to optimal image quality, the image format you choose is an important consideration. There are various types of image formats available, each with its own benefits and drawbacks in terms of quality, compression, and support. It's crucial to select a format that offers the highest quality with the smallest file size.

The most commonly used image formats on the web are JPEG, PNG, and GIF, and each has a specific use case. GIFs are ideal for animations and can store compressed data without losing quality. Meanwhile, PNGs support lossless compression and can store an unlimited number of colors, making them perfect for graphic design and images with transparent backgrounds. JPEGs, on the other hand, are best suited for photographs and images without transparent backgrounds due to their smaller file size and compression process.

To choose the right format for your images, consider the specific needs of each image. For product photos, JPEG is often the better choice, while PNG is more appropriate for graphics, files with transparent backgrounds, and images where clarity and vibrancy of color are essential. Ultimately, selecting the right image format can ensure that your store's images look professional and load quickly for your customers.

All in all, product images help attract customers and enhance their experience when shopping with you and its importance is often overlooked, especially for those who are new to starting an online store. But by following these best practices, you can improve your website’s performance, enhance your brand's reputation, and drive more sales.
