Usage tips

How to edit and export cleanly

Image Resize changes image dimensions for web, social, marketplace, and documentation use.

It is a quick way to create a predictable width or height while keeping the original aspect ratio when needed.

Common use cases

  • Resize screenshots before adding them to a knowledge base.
  • Create consistent product images for a catalog or marketplace.
  • Prepare smaller image versions for faster web pages.

How to use it well

  1. Upload one or more supported image files.
  2. Adjust size, quality, color, layout, or output options.
  3. Preview the result where available.
  4. Download the processed file and compare it with the original.

Practical tips

  • Keep aspect ratio enabled unless you intentionally need a stretched result.
  • Start from a high-resolution source image for cleaner exports.
  • Avoid upscaling small images too far because it will not add real detail.

Limitations to know

  • Resizing can soften fine details and text in images.
  • Very large source images may hit browser memory limits.
