Best practices for better results

Image optimization works best when you choose the right balance between file size, visual quality, dimensions, format compatibility and privacy. These tips help you get a cleaner result.

  • Start from the original image whenever possible.
  • Review the output before publishing or deleting your original file.
  • Use related tools like resize, convert or metadata removal when you need a more specific result.
  • Choose the right format for the job: JPEG for photos, PNG for sharp graphics and WebP for modern websites.

Compress an image to a target file size

Some upload forms reject images over a specific size, such as 100 KB, 500 KB, 1 MB or 2 MB. This tool lets you choose a target size and creates a JPG or WebP copy that tries to stay under that limit.

How to get under the target

  • Start with JPG for broad compatibility or WebP for smaller web images
  • Use a target like 500 KB, 1 MB or 2 MB
  • If the file is still too large, set a smaller max width
  • Keep your original file before replacing it with a compressed copy
Tip: Quality can only go so far. If a large camera photo cannot hit the target, resizing the dimensions is usually the next step.
