EXIF 查看与移除器 - 查看并清除照片元数据

EXIF（可交换图像文件格式）是相机和手机在每张照片中嵌入的隐藏元数据，包括设备型号、相机设置、精确的拍摄日期时间，以及最令人担忧的拍摄地点 GPS 坐标。在网上分享照片前移除 EXIF，可以防止陌生人通过一条 Instagram 帖子就推断出你的家庭住址。

Drop any JPG, PNG, HEIC, TIFF or WebP onto the tool and it lists every metadata field grouped by category: Camera (make, model, lens), Exposure (aperture, shutter, ISO, focal length), Date & Time, Location (GPS), and other XMP/IPTC fields. Your photo is uploaded over HTTPS to our secure server to read its metadata, then deleted automatically after processing — we never store, share, or sell it.

The cleaned image is re-encoded on our server at 95% quality JPEG (or lossless PNG if the source was PNG). For 99% of casual sharing this is visually identical; for archival originals you should keep an untouched copy. The metadata strip is total — no EXIF, GPS, IPTC or XMP block survives.

iPhone 默认会在每张照片中嵌入精确的 GPS 坐标。当你用 AirDrop 发送、发消息或上传这张照片时，GPS 信息也会一同传出去。任何拿到该文件的人都能在地图查看器中调出拍摄位置——包括前任、跟踪者，以及在社交媒体上抓取数据的机器人。公开分享前，请先清除 EXIF 信息。

Yes — the viewer decodes HEIC/HEIF metadata too. It surfaces lens model, aperture, ISO, and the full GPS block including altitude when present. The cleaned output is re-encoded as JPEG since HEIC is not universally supported.

大多数社交平台在上传时会去除 EXIF（这是好事），而截图默认会生成一份不含元数据的全新副本（这也是好事）。Photoshop 和大多数编辑器在「保存」和「另存为」时会保留 EXIF，除非你选择「导出为」并取消勾选「包含元数据」选项。在下定论之前，请始终用我们的查看器检查实际文件。

Yes — the Export JSON button saves every field the viewer finds, including raw GPS coordinates, camera serial numbers and timestamp precision. Photo forensics workflows often diff this JSON against expected camera profiles to detect manipulation.

Free, no signup, and no watermark. Your photo is uploaded over HTTPS only so the server can read its metadata and build the cleaned copy, then deleted automatically after processing — we keep no log of the photos you analyse, the metadata they contain or the cleaned versions you download.

可以。当照片带有位置数据时，「位置」部分会以可读坐标列出精确的 GPS 纬度和经度（如有海拔也一并列出）。你可以把这些坐标复制到任何地图应用中找到该地点，然后在分享照片前一键将其清除。

No. This is an online EXIF viewer — drop in a photo and every metadata field is read and shown on the spot, with nothing to download or install. It is a quick alternative to desktop metadata utilities; your photo is uploaded over HTTPS only to be read, then deleted automatically afterwards.

Use the 'Cleaned image format' dropdown in the Source panel to pick JPEG or PNG for the stripped copy, independent of your original file's format. Pick PNG if you need to keep transparency or want a lossless result, or JPEG for a smaller file when transparency doesn't matter — the tool re-processes the image the moment you change this setting.
