Optimising images can be difficult for some. There’s a lot of factors you need to consider to ensure the images used in your site is fully optimised. If you don’t have the time or the motivation to learn the basics of image optimisation, hiring an SEO professional is your best option. Your second best option would be to use Image Optimisation tools. In this article, I will list down several tools you can use to simplify your image optimisation task.
Quick Recall! Proper image optimisation can improve your site’s performance in numerous ways. First of all, optimised images provide context and communicate meaning to users. It makes your content easier to scan and digest. Second, it can also boost your site speed by making the loading time faster. Lastly, it gives search engine additional information on what the site is really about. All of these results to a better user experience.
What are the best free tools for image optimisation? There is no perfect one-size-fits-all image tool that you can use for all types of formats to meet all sets of optimisation parameters for any kind of image. Let’s be clear; there’s no perfect set of optimisation parameters that can apply to every image. However, there are several factors you need to consider. Like with the set of parameters, there’s also no perfect all-encompassing image optimisation tool that can cater to every kind of image. It is advisable that you mix and match to find what fits what. It all depends on the image format and the content’s visual and technical requirements.
According to Google, there are the best tools you can use: Gifsicle – for creating and optimising GIF images Jpegtran – for optimising JPEG images Optipng – for optimising lossless PNG pngquant – for optimising lossy PNG
However, even if the tools above might seem to be a little outdated (based from their website), don’t get deceived. They’re fully functional, and they can do the job right. But if you want a more “modern” optimisation tool, here’s another list of tools by the Envira Gallery Blog: JPEG Optimiser – for online JPEG compression and resizing Optimizilla – for online JPEG and PNG compression Kraken.io – for bulk JPEG, PNG and GIF optimisation ImageRecycle – for JPEG, PNG, GIF and PDF images optimisation CompressNow – for bulk JPEG, PNG and GIF optimisation Trimage – a cross-platform tool for PNG and JPG files Online Image Optimiser – for online JPEG, PNG and GIF optimisation Tiny PNG – for bulk online JPEG and PNG optimisation Resize Photos – for simple online image optimisation GiftOfSpeed – it includes other tools that can improve your overall site speed Compressor.io – for image optimisation up to 90% JPEGmini – for image size compression up to 80% Convert Image – for other image formats like BMP, GIF, ICO, PNG and more PNGGuantlet – for downloadable image compression
