Strip metadata from audio, images and videos. 👑 Written in Nim language

nimble install striptease / clue install striptease --build

API reference

😍 Key Features

• Open Source | MIT License
• Written in Nim language
• Zero dependencies, single static binary
• Audio: .wav — drops LIST INFO, id3, bext, iXML and friends (rebuilds file, keeps fmt + data)
• Images: .jpg / .jpeg (drops APP0–APP15, COM), .png (drops tEXt / zTXt / iTXt, eXIf, iCCP, tIME), .gif (drops comments, plain text and non-NETSCAPE app extensions), .webp (drops EXIF, XMP, ICCP)
• Video: .mp4 / .mov / .m4v (neutralises udta, meta, uuid, zeroes mvhd / tkhd / mdhd timestamps), .avi (neutralises LIST INFO, id3), .mkv / .webm (voids Tags, Attachments, Info title / date / apps)
• RAW photos: .cr2 .nef .nrw .arw .srf .dng (incl. Apple ProRAW) .rw2 .orf .pef .srw .tif / .tiff — zeroes Artist, GPS, XMP and thumbnail metadata in place. MakerNote is preserved (it can hold serials/shutter count, but removing it breaks Apple decoders).
• Canon .cr3 (EXIF uuid sanitised, XMP zeroed) and .heic / .heif (Exif item sanitised, XMP items zeroed, image items untouched). Stripped Live Photo stills and videos stay playable standalone but lose their Live pairing.
• Video-safe: size-preserving edits keep stco, idx1 and Cues offsets valid, no re-encode
• Text: .txt .text .md .markdown .json .csv .html .htm .xml .yaml .yml — strips invisible Unicode, exotic spaces, bidi overrides, tag chars (safe-preserve defaults: emoji glue, paired embeddings, script joiners kept)
• Media --inspect JSON values are scrubbed for invisible carriers
• --dry-run and --verbose reporting, --overwrite protection by default
• --inspect prints embedded metadata as pretty JSON without touching files

Usage

striptease 0.2.0 – strip metadata from photos, PDFs, videos, and documents

MIT license | Made by Humans from OpenPeeps
  https://github.com/openpeeps/striptease

usage: striptease <input|input-dir> --out:<dir> [options]

required:
  <input>             file or directory (mixed formats allowed)
  -o, --out:<dir>     output directory for cleaned copies
                      (single file input plus --out:foo.ext writes one file,
                       not needed with --inspect)

supported formats:
  audio: .wav | images: .jpg .jpeg .png .gif .webp
  raw: .cr2 .nef .nrw .arw .srf .dng .rw2 .orf .pef .srw .tif .tiff
  video: .mp4 .mov .m4v .avi .mkv .webm | canon raw: .cr3 | heic: .heic .heif .hif
  text: .txt .text .md .markdown .json .csv .html .htm .xml .yaml .yml

options:
  --dry-run           report only, write nothing
  --inspect           print metadata as pretty JSON, write nothing
  --verbose           per file kept and dropped chunks plus bytes saved
  --overwrite         overwrite existing files in out dir (default: skip)
  --keep-musical      WAV only: also keep cue, smpl, inst, acid chunks
  --nfkc              text: accepted for compat, NFKC normalize is currently a no-op in the Nim build
  --aggressive-homoglyphs text: map Cyrillic/fullwidth Latin confusables to ASCII
  --no-normalize-spaces text: keep exotic spaces as-is (default: rewrite to U+0020)
  --strip-emoji-glue  text: paranoid, also strip load-bearing invisibles (emoji glue, joiners, flag tags)
  --strip-bidi        text: also strip legitimate RTL/LTR marks and isolates
  --force-text        text: treat binary-looking input as text anyway
  -h, --help          show this help
  --version           show version

Examples

Strip a single photo (writes one file):

striptease photo.jpg --out:clean.jpg --verbose

Strip a mixed folder of audio, images and video:

striptease ./uploads --out:./clean --overwrite

Report only, write nothing:

striptease clip.mp4 --out:./clean --dry-run

Inspect embedded metadata as pretty JSON (writes nothing, --out not needed):

striptease photo.jpg --inspect

Keep WAV musical chunks (cue, smpl, inst, acid):

striptease take.wav --out:./clean --keep-musical

Strip invisible Unicode from text (safe defaults preserve emoji glue and RTL marks):

striptease notes.md --out:clean.md --verbose
striptease notes.md --inspect

Languages whose typography relies on a non-breaking space (French « … », the space before ; : ! ?) should pass --no-normalize-spaces. Invisible carriers are still removed; only the space rewrite is skipped. --nfkc is accepted for CLI compat but NFKC normalize is currently a no-op in the Nim build (stdlib has no NFKC table).
