1 How to Clean Photo Metadata
- • Select Photo: Drag & drop any JPEG, PNG, or WebP photo, or paste directly with Ctrl+V.
- • Inspect Detected Tags: Review GPS latitude/longitude coordinates, timestamps, and camera details found in the image.
- • Choose Format: Keep the original format or convert to modern WebP or standard JPEG with adjustable compression.
- • Download or Copy: Click Scrub & Download to save the clean file or Copy Clean to paste immediately.
★ EXIF Privacy Tips
- ✔ Smartphones embed exact GPS: Unless you disable location permissions in camera settings, every phone photo includes exact coordinates.
- ✔ Canvas rasterisation removes 100%: Drawing only visual pixels to an HTML5 canvas ensures no hidden binary tags can leak through.
- ✔ Convert to WebP to save space: Clean your photo and compress it into WebP format at the same time to reduce file size up to 50%.
- ✔ Zero quality loss at 95%: Keeping quality at 95% preserves crystal clarity while discarding unnecessary metadata overhead.

Under the Hood: Canvas Sanitisation & Binary Specs
Show technical details
Hide
Inspection uses high-speed binary parsing via exifr to read TIFF headers, EXIF IFD0/IFD1 tags, IPTC records, XMP XML payloads, and GPS SubIFD blocks directly from in-memory array buffers.
Sanitisation is guaranteed via pure HTML5 2D Canvas rasterisation. By drawing visual bitmaps onto an unlinked canvas context and re-encoding with native toBlob() APIs, all auxiliary metadata markers (APP1, APP2, Exif chunks) are completely discarded with zero metadata leakage risk.

❓ Frequently Asked Questions
Why do smartphones attach GPS coordinates to my photos?
Modern iOS and Android devices use location services to tag photos with coordinates so photo albums can organise pictures geographically. When sharing photos on classifieds, forums, or online marketplaces, these coordinates can reveal your exact residence.
How does canvas rasterisation guarantee metadata removal?
Instead of simply attempting to edit or delete binary header chunks, BWTools draws only the visual pixel matrix onto a fresh HTML5 canvas element. When exporting to a new blob, the browser generates a completely clean file container without any metadata headers.
Does scrubbing EXIF data reduce image quality?
No perceptible quality is lost. By setting the quality level to 95% or higher, or by choosing lossless PNG format, the re-encoded image retains all sharpness, contrast, and colour fidelity while stripping 100% of the metadata headers.
