    • Full screen size images (hero images) should be no larger than 1600px wide at 72dpi.

Next we have some guidelines when editing images and graphics for your website:

Editing images online can be super convenient and effective, especially with the right tools and techniques. Here are some best practices to follow when editing images online:


Choose the Right Tool

  • For basic edits: Use tools like Canva, Pixlr, Fotor, or Photopea.
  • For advanced edits: Go with Photopea (Photoshop-like), or Pixlr E (more powerful than Pixlr X).
  • For AI features: Try Remove.bg (background removal), Cleanup.pictures (object removal), or RunwayML (video/image AI editing).

Know Your Purpose

Tailor your edits based on your goal:

  • Social media: Use proper aspect ratios, bright colors, and light filters.
  • Web design: Optimize size and resolution for fast loading.
  • Print: High resolution (300 DPI), CMYK color mode (if the tool supports it).

Follow These Editing Steps

  1. Crop & Straighten – Clean up the framing.
  2. Adjust Lighting – Tweak brightness, contrast, exposure.
  3. Color Correct – Fix white balance, saturation, vibrance.
  4. Retouch/Enhance – Use healing tools or AI for blemishes, sharpening, etc.
  5. Add Text or Graphics – Keep it readable and well-placed.
  6. Resize/Compress – Match output format to your needs (e.g., web, print, etc.).

Keep Design Principles in Mind

  • Less is more: Avoid over-editing.
  • Consistency: Stick to a color scheme or visual style.
  • Hierarchy: Use fonts and contrast to guide the viewer's eye.
  • Alignment: Use grids and guides if available.

Export Smart

  • JPEG for photos (good quality + small file size).
  • PNG for images with transparency or sharp graphics.
  • WebP for web use (great compression without losing much quality).
  • Check the resolution (e.g., 1080x1080 for web images and Instagram posts).
  • Note that the average website browser screen is no more than 1600px wide, use this as a reference. IE: If you want an image to take half the page; size it to 800px wide.
  • WebP isn't necessary if you're using WordPress Plugins like WP Compress, or WP Rocket - these plugins will compress and convert all your images to WebP for you.

 

This should give you the basics to start editing images and graphics for your website.
