Guide

How to View Metadata Online

The safest way to check metadata online is to inspect the exact file you plan to share, look at the sensitive fields first, and then decide whether you need to keep it, clean it, edit it, or compare it.

Guide

What Is Metadata?

Metadata is the extra information stored with a file. It can be useful, but it can also reveal details you did not mean to share.

Guide

What Is EXIF Data?

EXIF data is a common group of photo metadata. It often includes camera details, timestamps, orientation, and sometimes location information.

Guide

How to Remove Photo Location Data

The safest way to remove photo location data is to inspect the exact image you plan to share, create a cleaned copy, and then check that new file again before sending it.

Guide

How to Edit Metadata Online

Online metadata editing works best when you change a small number of useful fields, export a new copy, and check that file again before you rely on it.

Guide

How to Check Document Metadata

For a quick document metadata check, start with title, author, producer, creator, timestamps, and page count, then decide whether the file is ready to share.

Guide

How to Use a PDF Parser Online

A PDF parser is most useful when you need quick answers about who created the file, how many pages it has, and whether it behaves like a text PDF or a scanned one.

Guide

What Is a File Signature?

A file signature is a recognizable byte pattern near the start of a file. It helps identify the underlying format even when the file name is misleading.

Guide

What Is a MIME Type?

A MIME type is a label such as image/jpeg or application/pdf that tells software what kind of file content it is handling.

Guide

How to Compare Two PDFs

A practical PDF comparison starts with the simplest signals: page count, title, author, producer, timestamps, and whether both files behave the same way when text is extracted.

Guide

How to Compare Image Metadata

The most useful image metadata comparison starts with GPS, timestamps, software, dimensions, orientation, and camera fields before you dig into deeper tag differences.

Guide

How to Read Video Metadata

For most online video checks, the useful fields are file size, dimensions, duration, playback behavior, and other basic format clues that help you spot the wrong file quickly.

Guide

How to Inspect Video Streams Online

An online stream inspector is best used for quick confirmation of file size, duration, dimensions, playback behavior, and other visible media details before you move on to a deeper review.

Guide

How to Check PDF Assets Before Cleanup

Before cleaning a PDF, it helps to know whether the file behaves like a text document, an image-heavy scan, or something in between.

Guide

How to Compare Two Videos Online

A good online video comparison starts with the basics: do the files match in duration, size, visible dimensions, and general playback behavior?

Guide

How to Remove Metadata From Files

Metadata removal is safest when you identify the file type first, inspect the original file, remove metadata where support is solid, and then check the exported copy again.

Definition

EXIF

EXIF is a metadata standard commonly used in photos. It can include camera details, timestamps, orientation, and GPS data.

Definition

IPTC

IPTC metadata is often used for captions, credits, keywords, and editorial information in image files.

Definition

XMP

XMP is a flexible metadata format used by many apps to store descriptive, rights, and file history information.

Definition

GPS metadata

GPS metadata stores location-related information such as latitude, longitude, and sometimes altitude.

Definition

MIME type

A MIME type is a label that describes the kind of content in a file, such as image/jpeg or application/pdf.

Definition

File signature

A file signature is a recognizable byte pattern near the start of a file.

Definition

DPI

DPI describes print density metadata, while pixel dimensions describe the actual amount of image data.

Definition

Document info

Document info usually refers to metadata fields such as title, author, subject, creator, producer, and timestamps.

Definition

Stream metadata

Stream metadata describes technical information about the audio and video streams inside a media file.

Definition

Page count

Page count is one of the fastest structural checks for PDF comparison and document review.

Format

JPEG photo

EXIF, IPTC, XMP, GPS, dimensions, signature. Strongest image format for metadata cleanup and editing.

Format

PNG image

Dimensions, signature, text metadata chunks. Useful for title, author, description, copyright, software, and comment fields.

Format

WebP, GIF, BMP, AVIF, HEIC, HEIF

Dimensions and readable metadata. Browser support varies, especially for HEIC and HEIF.

Format

SVG image

Title, description, viewBox, ID, version, dimensions. SVG can contain scripts or external references; treat unknown SVG files carefully.

Format

PDF document

Document info, page count, text sample, page signals. Asset removal is inspection/planning first; full redaction is not handled in-browser.

Format

Office and OpenDocument files

Package overview, document properties, app properties, custom properties. Cleanup is safer in the original office app because comments, revisions, and embedded objects need format-specific handling.

Format

Legacy Office files

Basic identification and file-level clues. Older binary Office formats need a heavier parser for deep metadata extraction.

Format

MP4, MOV, M4A

Container brands, duration, tracks, codec clues, common media tags. Common title, artist, album, comment, copyright, and encoded-by tags can be shown when present.

Format

WebM, MKV, OGG, OGV, Opus

Container details, tracks, duration, Vorbis/Opus comments where present. Support focuses on metadata inspection, not stream extraction.

Format

MP3, WAV, FLAC

Duration, format clues, ID3, RIFF INFO, FLAC/Vorbis comments. Tag coverage varies by encoder and tag version.

Format

EPUB ebook

Title, creator, language, identifier, package, cover, manifest signals. Other ebook formats fall back to basic file checks.
