Frequently Asked Questions

Why detect format from magic bytes?

File extensions can lie (for example, a WebP renamed to .jpg). Magic-byte detection identifies the actual encoding, which matters for compatibility.

Does the inspector modify my file?

No. The inspector is strictly read-only. Your file is never altered.

What is 'estimated quality'?

For JPEGs we estimate the quality tier from compression metadata. It is an estimate for guidance, not an exact measurement.
