Best practices

  • Image has been saved as a JPG, which is the ideal format for general web images. The jpeg file typically provides the best quality and size compression for photographs.
  • Image has been saved as a high quality jpg. This means the image is clear and mostly free of artifacts, which reduces the overall quality and clarity of the image.

Avoid these mistakes

File type

  • Don’t save the photo images as either a PNG or GIF. The JPG file typically provides the best quality and size compression for photographs.
  • Image has been saved as a JPG with low quality (~20%) and contains a large amount of artifacts. This will reduce the file size, but as you can see below the image has been too heavily compressed, resulting in a poor quality image which is not acceptable for use.

File size

  • Avoid uploading images which have a large file size. Aim for a 100-300KB file sizes. File size over 1MB is too large. This will slow down the loading of the page which affects user experience and search engine rankings.
  • Adhere to the recommended image dimensions. This will result in much smaller file sizes which enable faster loading of web pages.
