XnResize for Mac

Free image resizer for macOS

XnResize is a no-cost utility for macOS that focuses on resizing and optimizing images. It’s built to handle batches of photos at once, making it a practical choice for people who need to process many pictures quickly — from hobbyist photographers to professional designers.

Capabilities and format support

This app handles a wide selection of image file types and provides straightforward controls for streamlining large sets of images.

• Quickly rotate or flip pictures when needed.
• Define exact output dimensions and choose compression/quality levels.
• Process multiple files in a single operation to save time.
• Work with a broad range of common image formats.

Usability and simple edits

XnResize emphasizes an intuitive workflow, so resizing tasks can be completed with minimal steps. In addition to scaling images, it includes basic transformation tools that cover typical pre-publish or archive preparation needs.

Paid alternative: Adobe Photoshop

If you need more advanced editing and retouching capabilities beyond bulk resizing, Adobe Photoshop is a commonly recommended paid option. Photoshop adds extensive image-manipulation tools, layer-based editing, and professional-grade output controls for more complex projects.
