Czkawka vs Duplicate Photos Fixer Pro

Czkawka is a free tool for locating duplicate and unnecessary files, empty folders, similar images, and related items. Its tools can find duplicate and empty files, temporary and large files, similar videos, and duplicate music. Scans can target user-selected directories and files, with matches determined by file name, size, full-file hash, or a combination of size and name. Features include file preview, automatic selection, folder exclusions, and moving items to the Recycle Bin or Trash. The project provides graphical and command-line frontends, an Android frontend, a reusable core library, and Python bindings. It says the software uses multithreading and caching to help scans and later rescans, and that it has no internet access and collects no user information or statistics. Czkawka is listed for Android, Linux, macOS, and Windows. GTK 12.0 is the final release for that frontend, and no more GTK binaries are planned. Krokiet prebuilt binaries have no mandatory runtime dependencies, although its similar-videos tool requires ffmpeg at runtime.

Duplicate Photos Fixer Pro finds exact duplicates and similar-looking images, helping users organize photo libraries and recover storage. It can automatically mark photos for deletion, then group detected images so they can be previewed before removal. The product page lists support for JPG, PNG, TIFF, GIF, RAW, PSD and HEIC/HEIF files. On Windows, scans can include a PC, Dropbox without downloading its photos, and Lightroom Classic or Picasa libraries. Windows deletions go to the Recycle Bin, but duplicates on external drives are deleted directly. The maker lists Windows, macOS, iOS and Android versions; its Windows edition supports Windows 7 and later, in 32-bit and 64-bit versions. The Windows trial is available once per user and permits removal of up to 15 duplicate photos. The Windows license costs $39.95 a year, billed annually, for one year. A 60-day money-back guarantee is offered to customers who contact the company within 60 days of registration.
