Frequently Asked Questions

Image metadata (EXIF data) is hidden information embedded in photos by cameras and smartphones. This can include your exact GPS location, device model, date/time, camera settings, and even your name. When you share photos online, this data can reveal sensitive information about where you live, work, or travel.

Common metadata includes: GPS coordinates (latitude, longitude, altitude), device information (make, model, serial number), camera settings (aperture, shutter speed, ISO, focal length), timestamps (when photo was taken, modified, digitized), software used for editing, copyright information, and sometimes thumbnail previews of the original image.

MetaClear creates a clean copy of your image by redrawing it without any hidden data. This process captures only the visual pixels, leaving behind all metadata. Everything happens right in your browser - your images are never uploaded to any server.

MetaClear preserves your image quality by using PNG format for transparency support and high-quality JPEG encoding (92% quality) for standard photos. The visual appearance remains virtually identical to the original, but without any embedded metadata.

MetaClear supports JPEG, PNG, WebP, GIF, BMP, TIFF, and HEIC/HEIF formats. HEIC files (common on iPhones) are automatically converted to JPEG for compatibility. All formats can be sanitized and downloaded as metadata-free images.

Browser fingerprinting is a tracking technique that collects information about your browser, device, and settings to create a unique identifier. Unlike cookies, fingerprints cannot be easily deleted because they are based on your system configuration rather than stored data.

Websites can detect your browser type and version, operating system, screen resolution, installed fonts and plugins, timezone, language settings, hardware specifications (CPU cores, memory), WebGL renderer, canvas fingerprint, and sometimes your real IP address through WebRTC leaks.

WebRTC is a browser technology for real-time communication that can expose your real IP address even when using a VPN. To prevent leaks, you can disable WebRTC in browser settings, use browser extensions like uBlock Origin, or use browsers with built-in WebRTC protection like Brave or Firefox with proper configuration.

Use privacy-focused browsers like Firefox or Brave, enable tracking protection, use standard screen resolutions, disable unnecessary plugins, use a VPN, consider using the Tor Browser for maximum anonymity, and regularly clear your browser data. Our Digital Footprint tool shows your current fingerprint and provides personalized recommendations.

Tracking parameters are extra data added to URLs to monitor your clicks and behavior. Common examples include utm_source, utm_campaign (marketing analytics), fbclid (Facebook), gclid (Google Ads), and mc_eid (Mailchimp). These help companies track which links you clicked and where you came from.

URL shorteners (like bit.ly, t.co, tinyurl) hide the actual destination, which poses security risks. They can redirect to malicious sites, and the shortener service logs your click data. Always verify shortened URLs before clicking, and our Link Analyzer tool can help identify and warn about shortened links.

MetaClear identifies and removes known tracking parameters from URLs while preserving the essential parts needed for the link to work. We maintain a database of common trackers from major platforms like Google, Facebook, Twitter, LinkedIn, and marketing tools. The cleaned URL takes you to the same page without tracking your click.

No. All processing happens entirely in your browser. Your images, fingerprint data, and URLs never leave your device. We use Google Analytics for basic usage statistics (page views, tool usage), but this is anonymized and does not include any of your personal data or the content you analyze.

MetaClear is built with transparency in mind. All processing runs entirely in your browser, which you can verify by inspecting network requests in Developer Tools - no image or personal data is ever transmitted. We believe in privacy through verifiability.

You can verify this yourself using your browser's Developer Tools (F12). Open the Network tab before using any tool and watch for requests - you'll see no data being uploaded. Everything runs entirely in your browser.

Always remove metadata from photos before sharing, especially if they contain location data. Check what information is embedded using our Image Sanitizer tool, then download the clean version. Be particularly careful with photos taken at home, work, or places you visit regularly.
