Frequently Asked Questions

What does "Lossless" metadata editing mean?

Most editors re-save the entire image, which often involves re-compressing pixel data and losing quality. Our tool only modifies the metadata chunks (like tEXt in PNG or EXIF markers in JPEG) without touching the image stream itself.

Which formats are supported for lossless editing?

We currently support lossless chunk manipulation for PNG and marker-based editing for JPEG. For formats like WebP and AVIF, we use high-quality re-encoding to ensure metadata is preserved or stripped as requested.

Is my privacy protected?

Absolutely. All processing is done locally in your browser. Your images and their sensitive metadata are never uploaded to any server.
