Converseen vs FFmpeg

Converseen is a free batch image processor for Windows, Linux, macOS, FreeBSD and other operating systems. It converts, resizes, rotates, flips and compresses images, and renames groups using progressive numbers or prefix and suffix values. Through ImageMagick, it handles more than 100 formats, including DPX, EXR, GIF, JPEG, JPEG-2000, PNG, SVG, TIFF, WebP and HEIC/HEIF. It can turn a full PDF or selected pages into images with chosen dimensions and formats, and extract images from Windows icon files. Converseen is built with open-source frameworks and libraries including Qt and ImageMagick; its source is released under GNU GPL version 3. Linux installation options include source code, AppImage, Snap, Flatpak and distribution repositories. The program does not transfer information to other networked systems. The Free plan is free. Windows and Linux users need Ghostscript configured for PDF processing, and the macOS release is beta and not currently codesigned.

FFmpeg is free, open-source software for recording, converting, and streaming audio and video on Windows, macOS, and Linux. Its command-line tool converts media files between formats, supports local recording, and lists AVI among its output formats. Output protocols include HLS, RTMP, RTMPS, RTP, RTSP, SRT, and UDP. Hardware acceleration is available for encoding and decoding. Decoding support includes Vulkan, VAAPI, and OpenHarmony, and Vulkan codecs can work on implementations of Vulkan 1.3. The Vulkan compute approach supports FFv1 encoding and decoding and ProRes RAW decoding, but only for codecs designed for parallel decoding. FFmpeg’s transcoding components run in parallel, which can improve throughput and CPU use; gains may be limited when one component dominates the processing. The project accepts contributions through its Forgejo instance and offers mailing lists, IRC, forums, bug reports, a wiki, and conferences. Version 8.1 Hoare was announced as available for download on March 16, 2026.
