Converseen vs ON1 Resize AI

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.

ON1 Resize AI enlarges photos for prints, tighter crops, AI-generated images, and older-photo restoration. It can scale images up to 10×, with custom maximum scaling, and offers batch processing. The 2026 version includes a diffusion-based Highest Quality model and a faster Standard model for batch jobs and less powerful GPUs. Face recovery has a controllable strength setting. Print tools include mural tiling, gallery-wrap margins, sharpening and resolution presets, and soft proofing. Resize AI accepts RAW, PSD, PSB, TIFF, JPG, PNG, and HEIC files. It runs as a standalone app on macOS and Windows and as a plugin for Adobe Photoshop and Lightroom Classic. There is no free plan, but the fully functional 30-day trial has no limitations or watermarks, requires no credit card, and starts on first launch. The listed Photo RAW MAX plan costs $89.99 a year and includes the standalone app on three computers, an Adobe plugin, all ON1 apps, and future upgrades.
