How it works

Inspect. Understand. Clean. Verify.

ShareGlass does not send files to a server. Every detector and sanitizer runs in your browser or in the zero-dependency CLI.

01

Inspect the container

Read image segments, PDF objects, and Office package parts—not just the filename or visible text.

02

Explain the exposure

Turn obscure metadata fields and relationships into plain-language risks with exact evidence.

03

Create a copy

Remove supported metadata without overwriting the original. Risky transformations are opt-in.

04

Scan it again

Re-run every detector and compare content fingerprints before offering the cleaned download.

Format support

Useful today. Honest about limits.

PDF rewriting is intentionally disabled in v1: preserving xref tables, signatures, forms, and rendered output safely requires a dedicated rewrite engine. ShareGlass reports the risk instead of pretending a byte replacement is safe.

Frequently asked

Questions people ask before sending a file.

How do I remove personal information from a Word document?

Inspect the DOCX first, choose the supported author, comment, thumbnail, custom-data, or external-link actions, then create a separate safe copy. ShareGlass scans that copy again and never overwrites the original.

Can a photo reveal where it was taken?

Yes. JPEG, PNG, and WebP files can contain EXIF or XMP location and device data. ShareGlass identifies supported GPS metadata locally and can create a metadata-cleaned derivative.

Does ShareGlass upload my document or photo?

No. Inspection and supported safe-copy operations run in the current browser tab. There is no file-upload endpoint, account system, analytics script, or telemetry.

Does a clean report prove a file is safe?

No. ShareGlass reports the structures it knows how to inspect. It is not an antivirus scanner and does not promise anonymity, harmlessness, or complete metadata removal for every file format.
