Tips for Using These Services:

  • File Size Limits : Most free tools have restrictions on file size and resolution. Compress your image before uploading if necessary.
  • Watermarks : Some services add watermarks to free outputs. Check the terms before using them for professional projects.
  • Quality Expectations : While these tools work well for most images, extremely low-resolution or heavily compressed images may still show artifacts after enlargement.

If you need to process a large number of images or require higher-quality results, consider upgrading to a paid plan or using desktop software like Adobe Photoshop or Topaz Gigapixel AI.
