JPEG Audit analyzes JPEG photos online: view EXIF, IPTC and XMP metadata and GPS location, inspect the JPEG structure (markers, quantization and Huffman tables), detect anomalies and signs of tampering, compute a perceptual hash, compare two images, edit or remove metadata losslessly, and export an HTML or TXT report. It is free and needs no sign-up. Photos are processed in memory and never stored. Please enable JavaScript to run the analyzer.
