Manually optimizing your images before upload

If you want to take a manual approach, here are some ideal optimization settings you can apply to your image before you upload them to your WordPress website:

  • Ideal file size:
    • A file size below 70 kb is what you should be targeting. In case of heavy files closer to 300 kb, the best you can achieve is a 100 kb file size
    • Services like PixlrCanva, and Image Resizer can help you with basic editing and resizing needs.
  • Ideal file format:
    • Photographs should utilize a JPG file format while logos and basic representations should utilize PNG or SVG formats.
    • JPG and PNGs can likewise have a similar quality and more modest document size with the lesser-known organization, WebP.
    • JPEG 2000 and WebP have preferable web pressure over PNG or JPEG. Changing from JPEG and PNG to WebP can assist with saving worker space in light of the fact that the picture pressure keeps the sharpness of the first picture AND decrease document size by practically 35% in contrast with JPEG and 50 % to PNG.
  • Other tips:
    • Use a white background for your images instead of a transparent PNG.
