Cantaloupe vs ON1 Resize AI

Cantaloupe is a free, open-source, self-hosted image server that creates derivatives from high-resolution sources when requested. It can crop, scale, and rotate images for deep-zoom viewers and on-demand thumbnails, and conforms to every IIIF Image API version through 3.0. Sources may be filesystems, HTTP or HTTPS servers, S3, Azure Storage, or relational database BLOBs. Processing choices include Java 2D, JAI, TurboJPEG, Kakadu, OpenJPEG, Grok, FFmpeg, and PDFBox. Caches can use filesystem, Java heap, JDBC, S3, Azure Storage, or Redis implementations. Security options include selective image and text watermarking, image-region redaction, HTTPS, HTTP Basic authentication, and customizable authorization policies. Configuration uses environment variables or a .properties file, with most changes applying without restart. Java 17 is required at minimum. The project says no official Docker image is currently available.

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.
