In their own words
Fotosizer
Fotosizer is a Windows application for resizing and processing batches of photos and images. The free Standard Edition download supports resizing, rotation, renaming, watermarking, and image optimization, with preset-based batch automation. Resize controls include percentage, custom dimensions, one-side resizing, padding, aspect-ratio preservation, and cropping. It handles TIFF, JPEG, GIF, BMP, PNG, WMF, EMF, and WEBP, including animated GIFs and multipage TIFFs. In Windows File Explorer, users can select images and open Fotosizer from the right-click context menu. Professional Edition adds text and image watermarks, color adjustments, rounded corners, and completion actions. The download page lists Windows XP through Windows 11 in 32-bit and 64-bit versions; the shop says there are no Mac, Linux, iOS, Android, or Chromebook versions. Fotosizer is available in 35 languages. Its privacy policy says device and crash information is collected only if an application error occurs and the user elects to send a report. Purchases are handled by FastSpring, and Fotosizer says it does not receive customers’ credit card details. Professional lifetime licenses include free updates and future new versions.
ON1 Resize AI
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.
