OSX Preview Bug: Shrink an Image to 16 Terabytes?

Apple Preview is a built-in application on macOS designed for viewing and interacting with various file types, primarily images and PDFs. It is a versatile tool offering features extending beyond simple file viewing, making it valuable for personal and professional use.

Preview Features

• File Viewing: Supports multiple file types, including PDF, JPEG, PNG, TIFF, and more.
• PDF Editing and Annotation: Highlight, underline, or strikethrough text; add text boxes, notes, and comments; fill out forms and sign documents using a trackpad, camera, or saved signatures.
• Image Editing: Provides basic editing tools like cropping, resizing, rotating, and adjusting colors; annotate images with shapes, text, and lines.
• Document Management: Merge multiple PDFs, extract specific pages, and rearrange pages in a PDF with drag-and-drop functionality.
• Export and Conversion: Allows exporting files in different formats, such as saving an image as a PDF or converting between file types.
• Integration: Works seamlessly with other macOS applications like Mail and Messages for document sharing and integrates with iCloud for synchronization across Apple devices.

Apple Preview is a robust and user-friendly tool for handling a wide range of tasks, offering efficiency and simplicity for professionals. But today, I ran into this pretty cool (and ridiculous) bug. I wanted to resize an image using preview from 140px wide to 100px wide. Preview wouldn’t ever save it when I clicked OK. I think I figured it out – look at the Resulting Size (TB).

Doh!

Note: This bug has been fixed in new versions of OSX.
