Privmeta
PrivMeta removes metadata with browser-side processing and no file uploads, according to its open-source project.
About Privmeta
PrivMeta is a metadata removal tool that runs in the browser. According to its repository, file bytes are processed in the browser and are not uploaded by the cleaning code. It supports selected JPEG, PNG, WebP, GIF, PDF, DOCX, video and audio formats, and removes specific metadata structures in each one rather than claiming to remove all metadata. Formats such as AVI, OGG, HEIC/HEIF and TIFF are not currently supported.
The project describes its optional Sentry and Cloudflare operational telemetry as excluding file contents and file names. The repository page lists an MIT license and a project website at www.privmeta.com. The directory record lists pricing as unknown.
Key features
- Metadata removal for JPEG, PNG and WebP images
- Block-level removal for GIF files that keeps frames, timing and palette
- Removes standard PDF properties and identifiers, plus DOCX package and author identities
- Video and audio files processed without transcoding, including MP4, MOV, WebM, MKV and MP3
- Privacy regression harness compares output with ExifTool and scans for raw sentinel values
Best for: People who need to remove selected metadata from supported image, document, video or audio files and want processing to happen in the browser.
Good for
- File bytes are processed in the browser and are not uploaded by the cleaning code, according to the repository.
- JPEG and GIF handling uses lossless removal, and video and audio files are processed without transcoding.
- A local and CI-run verification harness checks metadata against ExifTool and runs on pull requests and pushes to master.
Watch out for
- AVI, OGG, HEIC/HEIF, TIFF and other unlisted formats are not currently supported.
- Coverage is structure-specific and does not claim to remove all metadata; the project directs users to its privacy model and format coverage documentation for exact targets and limitations.
- Optional Sentry and Cloudflare operational telemetry is part of the tech stack, so users should review it when assessing privacy.
