Tools

Each tool lives on its own page. Drop an image, get the result, nothing leaves your device.

Metadata

Remove or view EXIF, geotags and other hidden data in a file.

EXIF Remover

Popular

Strips EXIF, XMP, ICC metadata from JPEG, PNG and WebP byte-by-byte. Batch mode supported.

EXIF Viewer

Shows all metadata stored in an image — without removing it.

SVG Cleaner

Popular

Strips metadata, editor cruft (Inkscape/Figma/Illustrator), unused defs and overlong numbers from SVG. Supports batch.

PDF metadata

Shows the author, title and software embedded in a PDF — and removes them without re-saving the document.

Office document metadata

Popular

Shows the author, company, tracked changes and comments hidden in DOCX, XLSX and PPTX files — and strips them before you send the document. Batch supported.

C2PA inspector

Shows what software made an image and how it was edited — when JPEG or PNG carries C2PA / Content Credentials.

Audio metadata

Shows tags inside MP3, FLAC, OGG and Opus (artist, album, year, comments) — and strips them without re-encoding.

PDF redactor

True PDF redaction: blacked-out areas become black pixels, OCR cannot recover them.

AI image detector

Heuristic detector for AI-generated images: C2PA, EXIF Software, IPTC markers + noise analysis.

Video metadata

View and strip MP4 / MOV / M4V / 3GP metadata without re-encoding: iPhone GPS, capture date, software.

JPEG quality

Estimate JPEG quality (0-100) from quantization tables plus an ELA-style re-compression detector.

GPS on map

Pull EXIF GPS from a photo and show it on an OpenStreetMap map (with opt-in tile loading).

Colorization detector

Tells apart hand-colorized B&W photos from real colour film through Lab chromaticity analysis.

EPUB metadata

Shows and strips the identifying metadata buried inside EPUB books — the purchaser's Apple ID, Calibre fingerprints, Kindle ASIN, Adobe DRM markers. Batch supported.

PDF hidden-data inspector

Shows what is hidden in a PDF: metadata, embedded files, JavaScript, annotations, and selectable text (a failed black-box redaction check). Read-only; the file never leaves your device.

What’s Hidden in an Image

Shows hidden photo data: EXIF, GPS, XMP, IPTC, embedded thumbnail, AI prompts in PNG, and data after the end of the file. Read-only, in the browser.
