Can I decode JSON that has been URL-encoded multiple times?

The tool processes standard percent-encoding; repeated encoding layers may require manual iteration or additional steps depending on the specific encoding pattern.

Is there a file size limit for the JSON input?

The material does not specify file size restrictions; users should test with large payloads to determine practical performance limits.

Does the decoded output retain JSON formatting and syntax?

Yes, the tool is designed to restore the original JSON structure, maintaining proper formatting after percent-encoding is reversed.

Can I use this tool for commercial projects on the free plan?

No, the free plan is for personal use only; commercial use requires upgrading to the premium plan.
