Metadata

How it works

File properties and embedded tags are compared separately from content. Binary fields use full SHA-256 hashes; missing and unavailable fields remain distinct.

Steps

1. Open File information to compare file size, modified dates, SHA-256, image EXIF, audio tags and document properties side by side.
2. Common fields are shown first. All fields includes readable EXIF, XMP, IPTC, ICC, native audio tags, PDF properties and Office document properties. Binary fields and artwork are compared by SHA-256. Missing fields are distinguished from browser-unavailable data; unsupported or malformed metadata may remain unreadable.
3. Search metadata

Settings

Reading results

No important differences means agreement within the selected mode and rules. It does not establish identical file bytes, identical appearance or identical metadata. Check the relevant modes separately.

Important changes

Red marks changes considered important by the active rules. Text insertions and deletions also use the important-change color.

Minor changes

Blue retains changes treated as minor, such as ignored whitespace or differences within a tolerance. It does not mean the original data is identical.

Only on one side

Purple identifies content present on only one side where the comparison uses that category, such as an unmatched file or audio segment.

Not checked

Unchecked means the current mode or source cannot establish equality. Missing formula caches and unsupported content must not be read as equal.

Examples

The examples illustrate the selected comparison scope. For text-like formats they show extracted content, not a claim that every layout or embedded object has been compared.

Reports and downloads

Use the report or download control provided by the current comparison. Text and Office reports describe comparison rules; CSV uses tabular output, and visual comparisons can export images or PDF reports. A report is not an editable replacement for the original Office document. Display filters and report scope are separate.

Comparison limits

Browsers do not expose filesystem creation time. Vendor-private tags may be unavailable; embedded creation times are different fields.
