What image metadata can contain
A photo can include technical fields such as capture date, camera model, exposure settings and sometimes GPS coordinates. Exactly what is present depends on the device, app and editing history. Not every photo has location information, and not every metadata field presents a privacy risk, but checking is especially sensible before public sharing.
What browser re-encoding does
When a browser draws an image onto a canvas and exports a new JPEG, PNG or WebP, the newly generated file generally does not carry over the original EXIF metadata block. This is the approach behind the CompIMG Remove Image Metadata utility. It is not the same thing as a comprehensive forensic stripping tool, and format-specific color or ancillary data can vary by browser.
Other private details can remain visible
Even after metadata is stripped, the visible picture may reveal a person, address, car plate, workplace or landmark. GPS location could also be inferred from recognizable scenery or text in the scene. Review the pixels themselves and avoid relying on blur or pixelation as a secure redaction technique.
A safer sharing routine
Keep an untouched original in a private location. Export a duplicate with metadata removed, inspect the visible content, and confirm its resulting format before uploading to a public service. If privacy is particularly important, independently inspect exported metadata with a trusted local tool before sharing widely.
How CompIMG handles the file
Standard tools are processed on your device rather than sent to a CompIMG processing server. Optional AI tools are different: they must send the image to a configured external model provider. Read the site Privacy Policy before using any remote processing option.
