Choose the safer sharing path

Some people want to inspect first. Others already know they want a cleaned copy. BeforeShare supports both flows without uploading the file.

Inspect first

See what the file reveals before changing it

Open a file, review GPS data, author names, software tags, timestamps, and document history, then decide whether it is safe to share.

How It Works

Three steps. No sign-up. No server upload. Just clean files.

📁

Select Your File

Drag and drop or click to upload any supported file. We accept images, PDFs, and documents.

🔍

Inspect Metadata

See every hidden field — GPS location, camera info, author names, software versions, and more.

✨

Download Clean

One click removes all metadata. Download your clean file instantly. The original is untouched.

Invisible Data That Files Expose

Every file you share can reveal more than you think. Here's what we find and remove.

📍

GPS Coordinates

Photos embed your exact latitude and longitude. Anyone can see where you were when you took the shot.

📷

Camera & Device Info

Camera make, model, serial number, lens type, and settings — all embedded in every photo.

👤

Author & Owner Info

Your name, company, email, and copyright details stored in document and image metadata.

💻

Software & Versions

Editing software, operating system, and version numbers that create a digital fingerprint.

🕐

Timestamps

Creation dates, modification times, and editing duration that reveal your workflow.

🔗

Tracking & Unique IDs

Unique document identifiers, revision history, and edit tracking that follow files across the web.

Supported files and the hidden data they often carry

These pages answer the main questions people search for before sending files to clients, employers, newsrooms, and social platforms.

Images

Photos can expose location, camera model, timestamps, editing software, and AI provenance markers such as C2PA, creator-tool fields, and model tags.

  • GPS coordinates and geotags
  • Camera, lens, and phone details
  • Software, editing, C2PA, and AI tags
Remove EXIF from images

PDFs

PDFs often keep author names, producer data, titles, keywords, and creation timestamps even when the page looks clean.

  • Author, creator, and producer
  • Title, subject, and keywords
  • Creation and modification dates
Clean PDF metadata

Word documents

DOCX files can hold company names, revision history, templates, and editing time that users do not expect to share.

  • Author, company, and manager
  • Revision history and editing time
  • Template and application details
Clean DOCX metadata

Multi-file cleanup

When you need a safer batch workflow, process many files together and download one ZIP instead of cleaning them one by one.

  • Batch image, PDF, and DOCX cleanup
  • Single ZIP download
  • Useful before large outbound sends
Open batch cleaner

AI image metadata is now a core sharing risk

The newest demand is not just “remove EXIF.” People want to know whether an AI image contains C2PA, Content Credentials, prompt data, model tags, or creator-tool history before they publish it.

AI / C2PA

Inspect AI provenance first

Check for C2PA manifests, content credentials, creator-tool fields, and prompt/model metadata before changing the image.

AI / C2PA

Clean a local share copy

Create a fresh JPG, PNG, or WebP copy with removable metadata containers stripped in the browser.

AI / C2PA

Understand the limits

Metadata cleanup does not remove visible watermarks, platform server records, or details already baked into the image pixels.

Before you share a file, check these four things

Metadata removal is powerful, but it is only one part of safe file sharing. This checklist helps visitors avoid the most common mistakes.

01

Inspect hidden metadata first

If the file comes from a camera, phone, office suite, or design tool, review the hidden fields before sending it.

02

Remove location, identity, and AI provenance clues

GPS data, author names, company names, software tags, and AI provenance metadata can reveal more than the file owner expects.

03

Review visible page content separately

Metadata cleanup does not redact names, addresses, signatures, screenshots, or text that is visible on the page.

04

Use batch cleanup before large sends

When you are sending many attachments, use a repeatable workflow instead of trusting each file individually.

Frequently Asked Questions

Yes, completely free. No sign-up, no limits, no paid tiers. We believe privacy tools should be accessible to everyone.
Never. All processing happens locally in your browser using JavaScript. Your files never leave your device — we can't see them even if we wanted to.
We remove EXIF data (GPS, camera info, timestamps), IPTC/XMP fields, PDF info dictionaries (author, creator, dates), and DOCX properties (author, company, revision history, editing time).
For JPEG images, we re-encode at 95% quality to strip metadata — the visual difference is imperceptible. PNG files remain lossless. PDF and DOCX content is fully preserved.
Yes. BeforeShare is useful for cleaning documents before sharing with clients, regulators, or publishing online.
We currently support JPEG, PNG, WebP, PDF, and DOCX files.
It depends. For images with large EXIF blocks (common with smartphones), file size may decrease noticeably. For PDFs and DOCX files, the difference is usually minimal since metadata is a small portion of the total file.
No. Once metadata is properly stripped, it is permanently removed from that copy of the file. However, if the original file still exists on your device or cloud backup, its metadata remains intact. Always clean files before sharing.
Yes. You are free to remove metadata from files you own or have rights to modify. Removing metadata is a standard privacy practice. However, for copyrighted works, removing copyright notices may have legal implications in some jurisdictions.
Yes. EXIF data often contains an embedded thumbnail of the original image. Our tool removes this along with all other EXIF fields, ensuring no hidden previews remain — even if you cropped sensitive content from the main image.
Yes. GPS coordinates in photos can be accurate to within 3 meters. By analyzing GPS data from multiple photos, someone could determine your home address, workplace, daily routine, and frequented locations. Removing metadata before sharing is essential.
Taking a screenshot creates a new image with fresh metadata from your device — so the original EXIF data is lost. However, the screenshot still contains new metadata (your device model, timestamp, etc.). Our tool removes all metadata completely.
Some platforms often strip EXIF data when you post or send an image, but behavior changes by app version, file type, and how the file is shared. Sending a compressed image may remove some metadata, while sending the same file as a document or attachment may preserve it. The safest approach is to remove metadata yourself before sharing.
Use our free View Metadata tool to instantly see all embedded data, including GPS coordinates. Our privacy assessment automatically highlights sensitive fields like location data.
C2PA (Coalition for Content Provenance and Authenticity) is a standard that embeds cryptographic metadata into images to verify whether content is human-made or AI-generated. Major platforms and AI tools now embed C2PA data. Our tool can strip these markers.
Simply open BeforeShare in your mobile browser — no app needed. Our tool works on all devices. Upload your photo, and we'll strip all metadata instantly in your browser.
Yes! BeforeShare is a free online exiftool alternative that works directly in your browser — no command line, no installation needed. While exiftool is a powerful CLI tool for advanced users, BeforeShare offers the same core functionality (view and remove EXIF data) with a user-friendly drag-and-drop interface. Perfect for anyone who wants to remove EXIF data without learning terminal commands.
Currently, BeforeShare focuses on images (JPG, PNG, WebP), PDFs, and Word documents. For video files, you can use ffmpeg to remove metadata with the command: ffmpeg -i input.mp4 -map_metadata -1 -c copy output.mp4
Windows has a built-in option: right-click a file → Properties → Details → 'Remove Properties and Personal Information.' However, this only works for some file types and doesn't remove all metadata. BeforeShare provides deeper metadata removal for images, PDFs, and Word docs — and works on Mac, Windows, Linux, and mobile browsers.
While GDPR doesn't explicitly mandate metadata removal, it does require organizations to protect personal data — and metadata often contains personal data (author names, GPS coordinates, timestamps). Many organizations strip metadata as part of their GDPR data minimization practices. BeforeShare helps you comply by processing files entirely in your browser with zero data collection.
Google Photos preserves most metadata by default, including GPS location data. When sharing via link, all EXIF data remains intact. Even downloading images from Google Photos retains the embedded metadata. If privacy is a concern, always strip metadata before uploading to Google Photos or any cloud service.
For image, PDF, and document metadata removal — yes! BeforeShare provides a visual, browser-based alternative to ffmpeg's metadata stripping commands. No installation, no terminal, no learning command syntax. Just drag, drop, and download a clean file. For video files, ffmpeg remains the best option until we add video support.
