PRIVATE, OFFLINE METADATA REMOVER

Remove metadata from files without uploading them

Inspect hidden EXIF, GPS, author, date and media tags. Create a separate cleaned copy. Verify it before you save.

CHOOSE BY FILE TYPE

One cleaner, format-specific engines.

A photo, PDF and MP3 do not store metadata the same way. Start with the way you naturally name your file.

PHOTORemove metadata from photosRemove supported EXIF, GPS, camera, date, IPTC and XMP metadata from photos locally while preserving orientation and image quality.DOCUMENTRemove metadata from documentsRemove supported metadata from PDF, Word, Excel and PowerPoint files locally while keeping visible content and reporting hidden-content limits.VIDEORemove metadata from video filesRemove supported title, creator, location, date, comment and artwork metadata from MP4, MOV and WebM without re-encoding video or audio.AUDIORemove metadata from audio filesRemove supported tags, comments, dates and cover art from MP3, FLAC, standard RIFF/WAVE, M4A and single-stream OGG audio locally.

MORE THAN A DELETE BUTTON

See what changes before it changes.

KillMetadata separates private data from descriptive, functional, structural and unknown fields. You see what will be removed, what must stay, and what needs review.

1
Inspect

Signature-first detection finds the container behind the filename.

2
Explain

Every known field is grouped by action, privacy risk and coverage.

3
Rewrite

A new copy is created while the source remains untouched.

4
Verify

A fresh worker scans the output instead of trusting the writer.

CURRENT COVERAGE

Writer and verifier availability, stated plainly.

Full verification and mandatory partial coverage are shown separately.

Writer + verifier available

JPEG · PNG/APNG · WebP · GIF · PDF · DOCX · XLSX · PPTX · EPUB · ZIP · MP3 · M4A · FLAC · standard RIFF/WAVE · MP4 · MOV · WebM · TIFF/BigTIFF · single-stream OGG Vorbis/Opus/FLAC

Each file can still finish partial or be rejected when its structure is not fully covered.
Clean + mandatory partial

HEIC/HEIF · AVIF

Supported container metadata is removed and coded image bytes are hash-checked, but HEVC/AV1 codec-level metadata units are not parsed, so these results cannot be verified-clean.

A PRECISE PROMISE

Removes all supported privacy metadata — not “100% metadata-free.”

Visible text and faces, voices, steganography, filesystem attributes, hidden Office content and copies stored elsewhere are different problems. KillMetadata names those limits instead of hiding them.

COMMON QUESTIONS

Before you choose a file.

Privacy claims should be easy to check.

Are my files uploaded?

No. KillMetadata runs in your browser and has no server upload route. The file picker becomes available only after the static processor is cached and offline protection is active.

Does removing metadata change file quality?

Supported handlers do not decode or re-encode pictures or sound. Functional data such as orientation, color, timing and gapless playback is kept; removable codec user-data may be replaced without changing encoded frames.

How do I know the metadata is gone?

After creating a copy, KillMetadata terminates the writer and opens the output in a fresh worker. It reports verified-clean, partial or rejected before saving is allowed.

Does it remove visible names, faces or text?

No. It removes supported metadata carriers. Visible content, hidden Office content, steganography, filesystem attributes and previously shared copies need separate review.
