Image Compression Compared: Formats, Quality Settings, and File Size Realities | GoToolstack
Compare JPEG, WebP, and PNG compression realities. Real measurements from browser Canvas encoding, quality loss trade-offs, and transparency limitations.
Strip embedded GPS location coordinates, camera serials, and timestamps from images.
Photo EXIF & GPS Metadata Scrubber inspects and purges hidden metadata structures embedded inside digital photographs prior to public social sharing or web publishing. Digital cameras and modern smartphones routinely embed sensitive data—such as exact GPS latitude/longitude coordinates, capture dates, camera hardware serials, and device identifiers—into image file headers.
The scrubber inspects input JPEG (APP1/Exif markers), PNG (eXIf and tEXt chunks), and WebP files, cataloging all embedded metadata tags into an inspection report. Users review detected tags (camera model, exposure settings, timestamp, GPS altitude and coordinates) before executing the purge. The tool decodes raw pixel arrays and re-encodes them into a clean container stripped of non-visual metadata.
Concrete Scenario: A homeowner takes a smartphone photo of furniture to list on an online marketplace. Uploading the 4.1 MB JPEG reveals embedded GPS coordinates pointing directly to their residential home address, along with iPhone device serial numbers. Clicking 'Scrub & Download' strips all 38 metadata tags in 90 milliseconds, delivering a sanitized 1.8 MB JPEG safe for public listing.
Because binary parsing, header stripping, and canvas re-encoding operate locally inside browser memory, private home coordinates, daily routine timestamps, and device identifiers are never transmitted to third-party tracking servers.
