Batch Remove Image Metadata
Create metadata-clean copies of up to 20 images by decoding the visible pixels in your browser and re-encoding them as JPEG, PNG, or WebP. The queue reports dimensions, output format, and size, then packages only verified results into one ZIP.

专为可靠的批量工作而打造
Canvas re-encoding commonly removes EXIF, GPS, camera comments, and many ancillary chunks, but this page does not claim forensic sanitization of every possible format or browser implementation. It accepts browser-decodable still images and makes flattened delivery copies, not archival replacements.

How to use Batch Remove Image Metadata
四步工作流程将原始文件与生成的输出分开。
- 1
添加文件
Select up to 20 images and choose an output policy.
- 2
选择设置
Decode each visible image locally in the browser.
- 3
本地处理
Re-encode and verify a clean flattened copy.
- 4
验证并下载
Download the ZIP and inspect representative metadata separately.
这个批处理工具的作用
Canvas re-encoding commonly removes EXIF, GPS, camera comments, and many ancillary chunks, but this page does not claim forensic sanitization of every possible format or browser implementation. It accepts browser-decodable still images and makes flattened delivery copies, not archival replacements. Every item is handled independently, so one unsupported or damaged file does not erase successful work from the rest of the queue.

Batch Remove Image Metadata guide
使用这些检查来获取适合目标的输出，而不是在成功下载时停止。
Know what browser re-encoding removes
A browser canvas receives decoded pixels rather than the source container structure. When those pixels are encoded into a new JPEG, PNG, or WebP file, EXIF blocks, GPS coordinates, comments, thumbnails, editing history, and most original ancillary chunks are normally absent. This is practical for publishing copies, especially when location or device details should not travel with an image.
Know what this workflow does not prove
Metadata handling varies by browser and output codec, and a visual image can still reveal sensitive information in its pixels. Text, reflections, faces, badges, screens, landmarks, and backgrounds are not metadata. The page also does not inspect proprietary containers, layered documents, or hidden content outside formats the browser can decode. High-risk privacy work needs a dedicated inspection process and independent verification.
Choose an output format intentionally
JPEG is efficient for opaque photographs but flattens transparency and uses lossy compression. PNG can preserve alpha and exact decoded pixels but may be much larger for photographs. WebP provides a modern balance where browser support is available. The automatic option retains JPEG, PNG, or WebP according to the source when possible, while unsupported output encoding falls back visibly rather than using a false extension.
Keep masters and verify delivery copies
Re-encoding removes more than private metadata: it can omit color profiles, captions, copyright notices, accessibility information, and camera orientation details. Keep original masters in controlled storage and use the clean ZIP for a specific publishing purpose. Open several outputs, compare color and sharpness, run an independent metadata viewer where privacy matters, and confirm that file-size changes fit the destination.
批次质量检查表
当源集合很有价值时，从副本开始，并保留可让您将每个结果追溯到其原始结果的文件名。在处理整个队列之前测试一个小的代表性集，包括最大的文件、透明图像、肖像和风景图像。处理后，比较实际目标中的像素尺寸、格式、文件大小、透明度、文本清晰度、边缘细节和颜色。成功的浏览器状态确认该工具已完成并验证了其预期的输出结构；它不能取代编辑审查或接收平台的规则。保留下载的 ZIP 或 CSV 以及用于运行的设置，然后记录需要单独处理的异常。对于发布工作流程，还要检查描述性替代文本、权限、同意、命名约定、备份策略和缓存行为。这些步骤使可重复的批次比将每个已完成的下载视为自动准备生产更安全。
常见问题
有关格式、隐私、质量和浏览器行为的实用答案。
What metadata is usually removed?
Canvas re-encoding commonly omits EXIF, GPS, camera comments, embedded thumbnails, and many source-specific chunks.
Is this a forensic metadata sanitizer?
No. Browser behavior and formats vary, so sensitive workflows should verify results with an independent specialist tool.
Does the image quality change?
JPEG and WebP may be recompressed; PNG preserves decoded pixels but can change container details and file size.
Will transparency remain?
PNG and supported WebP output can preserve alpha. JPEG requires a solid background.
Can visible private information be removed?
No. The tool does not redact faces, text, screens, reflections, or other information already present in the pixels.
Are images uploaded?
No. Decoding, re-encoding, validation, ZIP creation, and download stay in the browser.
Should I delete my originals?
No. Keep protected masters because useful metadata and quality can be lost in publishing copies.
