  • Checking results in the browser before saving the final file or copied output.
  • Working with personal, school, office, or creator files in a simple local workflow.

Common mistakes

  • Sharing the output without opening it once to confirm the result matches the intended task.

Limitations

  • Very large files can be slower or fail if the browser runs out of memory.
  • Browser support, file structure, fonts, encryption, or media codecs can affect the final result.
