Resize Image vs Compress Image

Resize changes pixel dimensions. Compression changes encoding quality or format size. Use resize first when dimensions are too large.

Decision

Which one fits the task?

Use Resize Image

  • The image dimensions exceed requirements.
  • You need social, portal, or thumbnail sizes.
  • Pixel count is the main source of file size.

Use Compress Image

  • Dimensions are already correct.
  • You need a smaller file without changing layout dimensions.
  • The destination accepts the current dimensions.

Avoid

Common mistake

Compressing a 6000px source is usually worse than resizing to final dimensions first.
