Details

How this works

Explore file magic bytes

Choose any local file and compare first bytes, likely type, MIME type, extension, mismatch status, and safe next actions.

Output 
Copy or download the finished result
Edge cases
  • Large inputs can take longer on slower devices.
  • Invalid or unsupported input returns a clear error.
Accuracy
  • This is file identity inspection only. It is not a malware scanner, reputation check, or authenticity verdict.
  • Review generated output before using it in production work.
Privacy
  • Input is processed locally in the browser.
  • Telemetry avoids raw input, filenames, secrets, and generated output.

Guide

How to use Magic Bytes Explorer

Step-by-step

  1. Choose or enter any in the workbench.
  2. Run the inspection tool locally in your browser.
  3. Review the signature-report result, then copy or download it if the workbench offers that action.
  4. Use the related tools on this page for cleanup, validation, conversion, or the next step in the workflow.

Questions

Is Magic Bytes Explorer free to use?

Yes. The public tool is free to use in your browser.

Are my files uploaded?

No. This tool runs locally in your browser, so selected files or pasted input are not uploaded to Convurter.

What should I check before using the signature-report result?

This is file identity inspection only. It is not a malware scanner, reputation check, or authenticity verdict. Review the final output before using it in production work.

What can I do after this?

Good next steps include File Type Checker, File Metadata Viewer, and File Checksum.

Workflow fit

Use Magic Bytes Explorer in the right place

If you are unsure, use the related tools and family hub to choose the closest workflow before committing to an output.

Best for

  • Local file and archive workflows where packaging, extraction, listing, type checks, metadata, or hashes help before sharing.
  • Inspecting what a file appears to be before using it in a larger workflow.
  • A focused inspect task where the expected output is signature-report.

Before you start

  • This tool runs in the browser, so keep the tab open until the result is created and downloaded or copied.
  • Treat files and archives from unknown sources as untrusted, even when the extension looks normal.
  • List archive contents before extraction when you only need to inspect what is inside.
  • Keep source files until the ZIP or TAR output has been opened and checked.
  • Use the report as a decision aid, then route to cleanup, conversion, or verification tools if it finds something notable.

Quality checks

  • Treat inspection output as a signal report, not as a guarantee that every possible issue was checked.
  • Verify file count, names, sizes, checksums, and detected type against what you expected.
  • Remember that file type and metadata inspection are not malware scanning.
  • Checksum final artifacts when exact byte identity matters.
  • Copy or download the result only after confirming the displayed output matches the task you intended.

Common mistakes

  • Opening extracted files automatically is risky; inspect and download deliberately.
  • Assuming an extension proves file type. Byte signatures and browser metadata can disagree.
  • Using checksum output as proof that a file is safe. Checksums prove identity, not safety.
  • Closing the tab before downloading or copying a browser-generated result.
  • Treating the first result as final without checking the destination requirement.

Verify or clean up

Use these when the output needs checking, cleanup, comparison, compression, or a final share-ready pass.

Archive Path Traversal Checker

Execution depth

Finish the job with fewer retries

Use these checks when the result will be emailed, uploaded, published, imported, or used as a final handoff copy.

Good uses

  • Check a renamed download.
  • Compare first bytes, MIME type, and extension before opening or uploading.

Bad inputs

  • Expecting malware detection.
  • Using a byte signature as proof of authenticity.
  • Relying on it for obscure proprietary formats.

Output checklist

  • Check extension mismatch status.
  • Route ZIP files to archive path review.
  • Use checksums when comparing against a trusted published hash.

Failure modes

  • Unknown types remain unknown.
  • Container formats can share ZIP signatures.
  • Very small or truncated files may only show weak signals.

Runtime limits

  • Browser-local.
  • Reads first-byte and metadata signals.
  • No upload or malware verdict.
