ABDiff brings precise file comparison to iPad. Choose two files or folders from the Files app and see exactly what changed. Everything runs locally on your device—no uploads, accounts, telemetry, or cloud processing. Compare text and code: - Review changes side by side with word-level highlighting. - Search, navigate changes, and copy the content you need. - Open a single text file for focused inspection. Compare documents and data: - See visual and extracted-text changes between PDFs. - Compare CSV, TSV, TXT, XLS, XLSX, and supported bank-statement formats as readable tables. - Review folders by relative path, filter results, and copy files between sides. Inspect images: - Use split, crossfade, difference, SSIM, and Delta E views to find visual changes. - Zoom and pan both images together, or highlight changed regions with boxes. Understand binary files: - Compare raw bytes in a fast hex diff. - Search in hexadecimal, text, or decoded encodings. - Inspect supported formats as structure trees linked directly to their bytes, including archives, certificates, databases, PDFs, spreadsheets, images, audio, and network captures. Built for iPad: - Open documents in place from Files and other document providers. - Use included samples to explore every comparison mode. - Keep sensitive files private: processing stays on your device.
