What is cleanthis.io?

A free online tool that scans your file for malware, removed hidden macros & scrips, and strips tracking metadata. The tool enables you to choose your sanitization mode depending on your needs and your threat model.

How it works

Three steps. No accounts, no tracking.

01

Upload or paste a link

Drop a file up to 50 MB or paste a URL from Drive, Dropbox, GitHub. No sign-up.

02

Pick a sanitization level

Light just strips metadata. Standard runs full CDR. Aggressive converts to safest format.

03

Download the clean file

Get back the original format with macros, scripts, EXIF and threats removed. View a full report.

Light

For files you mostly trust.

A virus scan and a clean wipe of hidden metadata. No re-encoding, no structural changes — your file comes back almost identical to what you uploaded, just without EXIF, GPS coordinates, author info, timestamps, or other metadata leakage.

  • Removes EXIF, GPS, author info, timestamps, embedded tracking metadata
  • Keeps format, fidelity, fonts, layout, full editability
  • Best for photos before sharing, documents from a trusted source, quick metadata audits
Standard · default

Trust nothing. Keep the format.

Full Content Disarm & Reconstruction. Macros, scripts, embedded objects and metadata are stripped; the file is re-encoded and rebuilt from safe content only. You get the same format back, minus the threats — without converting your .docx into something else.

  • Removes macros, scripts, embedded objects, OLE, metadata, hidden code paths, steganographic payloads
  • Keeps original format, visible content, basic editability
  • Best for the everyday case — anything from an unknown source you still want to open in its native app
Aggressive

Maximum safety. Editability takes a back seat.

Standard sanitization, then the file is converted to its safest counterpart — Office to PDF, images to PNG, HTML to plain text, video to MP4. The result is harder to weaponise, but you lose the original format and most of its editability.

  • Removes everything Standard removes, plus format-level complexity
  • Converts Office → PDF, images → PNG, SVG → PNG, HTML → TXT, EPUB → PDF, audio → WAV, video → MP4
  • Best for high-risk attachments, files headed into a sensitive environment, or where you only need the visible content
