Built for Privacy.
Designed for Simplicity.

Zap Metadata was created to eliminate the unseen surveillance footprint embedded in everyday digital files — without ever asking you to trust a remote server.

The Problem We Solve

The Silent Digital Exhaust in Everyday Files

Whenever you snap a photo on a smartphone, export a presentation from an office suite, render an artwork with generative AI, or record a video clip, your device quietly burns hidden personal forensic data into the binary structure of that file.

This data — known collectively as metadata — includes precise satellite GPS coordinates, device serial numbers, your personal name, your employer's corporate domain, internal file paths, full editing timestamps, and even the exact text prompts used to synthesize AI imagery.

When these files are uploaded to social media, shared in email threads, or submitted as public documents, anyone with basic software can read your coordinates, inspect your device profile, and reconstruct your private life.

⚠️

The "Online Converter" Trap

When users look for tools to strip this data, they typically encounter legacy web utilities. Almost all of these tools require you to upload your files to their remote cloud servers. Your private family photographs, confidential legal filings, and proprietary creative drafts end up sitting in third-party server queues, subject to server breaches, logging, and monetization.

We built Zap Metadata to put an end to this compromise.
Our Philosophy

The Four Core Pillars of Zap Metadata

🔒

1. Zero-Server Privacy

We believe true security means not having access to user data in the first place. Every operation runs in client-side memory using modern JavaScript and WebAssembly. No files ever travel over the internet.

💎

2. Lossless Binary Accuracy

Other tools degrade photos by re-encoding them through HTML canvases, introducing compression blur and color shifts. Zap Metadata surgically cuts out metadata segments at the binary byte level, leaving your pixels 100% untouched.

🌐

3. Frictionless & Universal

Privacy should not be gated behind monthly subscriptions, credits, or mandatory user accounts. Zap Metadata is free, lightning fast, and works identically across iPhones, Androids, Mac, Windows, and Linux.

🔍

4. Radical Transparency

We don't ask for your faith. Anyone can open their browser's Network inspector (DevTools F12) and inspect every byte transferred. Zero outbound uploads, zero third-party telemetry, zero hidden trackers.

Who Relies on Zap Metadata

📰

Journalists & Sources

Investigative reporters, whistleblowers, and human rights researchers sanitize photos and field documents to protect confidential sources and prevent geolocation tracking.

📷

Photographers & Creators

Commercial photographers strip sensitive client location metadata and proprietary camera settings while preserving full-resolution master image fidelity.

⚖️

Legal & Medical Teams

Attorneys, accountants, and healthcare professionals remove internal usernames, revision manifests, and printer identification from PDFs and Word documents before public filing.

Engineering

Under the Hood: Native Binary Stream Engineering

Building a lossless, zero-server metadata stripper required custom binary parser implementations for each file specification:

  • JPEG / JPG: Traverses the stream segment-by-segment. Removes APP1 (EXIF / GPS / XMP), APP13 (IPTC), and COM markers while preserving SOI, DQT quantization tables, DHT Huffman tables, and SOS image scan streams with exact bitstream fidelity.
  • PNG: Parses PNG chunks, stripping tEXt, zTXt, iTXt, and eXIf chunks while retaining IHDR, PLTE, IDAT, and IEND.
  • WebP: Rewrites the RIFF container header, calculating exact byte offsets after removing the EXIF and XMP sub-chunks.
  • PDF: Strips Document Information dictionaries (/Author, /Creator, /Producer, /CreationDate) and removes embedded XMP stream packets before rebuilding the cross-reference table.
  • DOCX, XLSX, PPTX: Decompresses the Open Packaging Conventions (OPC) zip structure in memory, sanitizes docProps/core.xml and docProps/app.xml author identifiers, and reconstitutes the clean archive.
