免费在线 EXIF 清除器

元数据是相机、手机和软件自动记录在文件里的“不可见属性”。照片常含有精确到米级的家庭 GPS 坐标和相机序列号，文档常记录有真实姓名、公司与修订历史。公开发布可能导致严重的个人信息泄露。

绝不会！与传统网站不同，Metadata Viewer 完全利用浏览器中的 JavaScript 本地运算，您的文件从未离开过您的手机或电脑。

不会。对于 JPEG 等格式，我们直接在二进制字节层面剥离 EXIF 和 XMP 头部数据，完全不触及和重新压缩图像像素，画质 100% 保持原本质量。

可以！您可以自由选择仅移除敏感的 GPS 地理标签，同时完整保留光圈、快门、ISO 与镜头参数用于摄影交流。

是的，100% 永久免费。无需注册账号，没有订阅套餐，也没有隐形的文件大小付费限制。

To view EXIF metadata using an online viewer, open Free Metadata Viewer in any modern web browser. Simply drag and drop your image file (JPEG, PNG, HEIC, TIFF, WebP, or RAW) into the upload area or click to select it from your device. The online viewer will instantly parse the embedded EXIF tags—including camera make and model, shutter speed, aperture (f-number), ISO sensitivity, focal length, capture timestamp, and GPS coordinates—directly inside your browser without uploading your files to any external server.

Using an online EXIF viewer is simple and takes just three steps:

1. Select your photo: Open the EXIF Viewer and drag your photo into the inspection box or click 'Choose File'.
2. Inspect metadata categories: Browse through organized sections including Camera Hardware (make, model, lens specifications), Exposure Settings (aperture, shutter speed, ISO, white balance), Timestamps (creation and digitized dates), and Geolocation.
3. View map or export: Check the photo's GPS coordinates on an interactive satellite map, export the complete tag report as JSON, or switch to the EXIF Remover if you wish to sanitize sensitive tags before sharing.

The best free online EXIF viewer tools prioritize user privacy, format compatibility, and thorough metadata parsing without file size limits:

• FreeMetadataViewer.com (Top Pick): 100% private and runs entirely in your browser using client-side Web APIs. Your images are never transferred over the network. Supports JPEG, PNG, HEIC, TIFF, WebP, RAW, PDF, and video formats with interactive GPS maps and before-and-after diff verification.
• ExifTool by Phil Harvey: The definitive open-source command-line utility for power users and developers needing deep tag inspection.
• Browser-Based Image Inspectors: Built-in browser developer tools or lightweight browser extensions for inspecting web-hosted photos on the fly.

An EXIF viewer is a specialized software application or online utility designed to read, decode, and display Exchangeable Image File Format (EXIF) metadata embedded inside digital photos. When a digital camera, smartphone (iPhone, Samsung, Pixel), or drone captures an image, it embeds a wealth of technical and contextual parameters into the file header. An EXIF viewer extracts this hidden information and presents camera model, lens hardware, exposure settings (shutter speed, aperture, ISO), timestamps, and GPS coordinates in a human-readable format.

You can use an EXIF viewer in Google Chrome using two convenient methods:

1. Online Web App (No installation needed): Open Chrome, navigate to FreeMetadataViewer.com/exif-viewer, and drag and drop any image directly into the Chrome tab. Chrome's modern JavaScript engine will decode the EXIF parameters locally in memory without uploading the file.
2. Chrome Web Extension: Install an EXIF viewer extension from the Chrome Web Store. Once installed, right-click on any image while browsing the web and select 'View EXIF' or 'Show Image Info' from the context menu.

You can view photo metadata natively on any operating system or online across all devices:

• Online (Universal): Drop your photo into FreeMetadataViewer.com for complete EXIF, IPTC, and XMP metadata on any desktop or mobile browser.
• Windows: Right-click the photo file, click Properties, and open the Details tab.
• Mac: Open the photo in Preview, press Cmd + I, and select the 'Exif' or 'GPS' tab.
• iPhone: Open the photo in the Photos app and swipe up or tap the (i) info button.
• Android: Open the picture in Google Photos or the native gallery, and swipe up or tap the three dots (⋮) menu.

To view image metadata across different formats (including JPEG, PNG, HEIC, WebP, GIF, TIFF, and SVG), open Free Metadata Viewer in your browser and upload the image. The tool reads all embedded metadata chunks—such as EXIF camera profiles, IPTC editorial copyright details, XMP editing records (from Photoshop or Lightroom), ICC color spaces, and even AI generation parameters (prompts, negative prompts, and seeds from Stable Diffusion or Midjourney) stored in PNG text chunks.

To view picture metadata, drag your picture into an online viewer like FreeMetadataViewer.com or inspect it using your operating system's built-in file manager. In Windows, right-click the picture file, select 'Properties', and click the 'Details' tab to view resolution, camera model, date taken, and color representation. On macOS, open the picture in Preview and press Cmd + I (Show Inspector). An online metadata viewer provides deeper technical details like lens model, focal length, and GPS coordinates on an interactive map.

To view PDF metadata:

• Online: Drag and drop your PDF into Free Metadata Viewer to inspect document Title, Author, Subject, Keywords, Creator tool, Producer software (e.g., Acrobat Distiller, Quartz), Creation Date, Modification Date, and PDF specification version.
• Adobe Acrobat / Reader: Open the PDF, click File > Properties (or press Ctrl + D / Cmd + D), and view the Description tab.
• Web Browser: Open the PDF in Google Chrome or Microsoft Edge, click the document menu, and select Document Properties.

To view metadata for any file type (images, documents, videos, and audio):

1. Open FreeMetadataViewer.com in your web browser.
2. Drag and drop any supported file—including photos (JPG, PNG, HEIC), videos (MP4, MOV, MKV), audio (MP3, WAV, FLAC), or documents (PDF, DOCX, XLSX).
3. The file-aware analyzer automatically detects the file container and displays all available metadata tags—including ID3 audio tags, video codec parameters, EXIF camera profiles, author details, and embedded GPS locations.

There are several quick ways to view EXIF data on macOS:

1. Preview App: Double-click the photo to open it in Preview. Press Command + I (or go to Tools > Show Inspector), then click the Exif tab or GPS tab.
2. Apple Photos: Open the Photos app, select the picture, and click the Info button (i) in the toolbar or press Command + I.
3. Finder: Select the file, press Command + I to open 'Get Info', and expand the 'More Info' section to view camera make, focal length, and aperture.
4. Online: Visit FreeMetadataViewer.com in Safari or Chrome for a full EXIF breakdown with an interactive satellite GPS map.

On an iPhone running iOS 15 or later:

1. Open the Photos app.
2. Tap the photo you want to examine.
3. Swipe up on the photo or tap the Info button (the (i) icon at the bottom of the screen).
4. You will see the date and time, camera model (e.g., iPhone 15 Pro Max 24mm f/1.78), shutter speed, ISO, aperture, megapixel count, file size, and an interactive Apple Maps view showing the exact GPS location where the photo was taken.

To view EXIF data on an Android smartphone:

1. Open the Google Photos app (or your device's default Gallery app).
2. Tap on the image to view it full screen.
3. Swipe up on the screen or tap the three dots (⋮) menu in the top-right corner.
4. The details panel will show the capture timestamp, camera model, lens specifications, exposure parameters (ISO, shutter speed, aperture), image resolution, and a Google Maps card displaying the photo's GPS location if geotagging was enabled.

To view the EXIF data of a photo, drag and drop the image into Free Metadata Viewer's EXIF tool. The inspector will instantly decode the binary EXIF tags embedded in the header of the JPEG, TIFF, or HEIC file. You can inspect the camera make and model, lens details, shutter speed, f-stop aperture, ISO, exposure compensation, flash status, metering mode, white balance, original capture date, and GPS coordinates.

You can view EXIF data in several ways depending on your preferred platform:

• Web Browser (Fastest): Use FreeMetadataViewer.com for instant, zero-install, private EXIF analysis with interactive GPS maps.
• Desktop: Use Windows File Explorer (Properties > Details), Mac Preview (Cmd + I > Inspector), or open-source software like ExifTool and Digikam.
• Smartphone: Swipe up on any picture in Apple Photos (iPhone) or Google Photos (Android) to inspect camera settings and location.
• Command Line: Run exiftool filename.jpg in your terminal for complete technical tag extraction.
