Pulling individual pages out of a PDF, dropping others in and even turning images into new PDF pages immediately establishes that Preview can handle considerably more document manipulation than its simple interface suggests. The demonstration is strongest when it focuses on these practical shortcuts: rearranging pages through thumbnails or the contact sheet, merging documents by dragging between windows and grabbing the file icon directly from the title bar. These are small features individually, but together they make a persuasive case for treating Preview as a lightweight document-management tool rather than merely a reader.
The discussion of redaction is particularly useful because it addresses a meaningful distinction between hiding information visually and actually removing it. The presenter warns against simply covering sensitive material with a black shape and instead demonstrates Preview's dedicated redaction tool, explaining that saving removes the underlying text or image data. That security-minded advice fits naturally into the tutorial rather than feeling like an unrelated warning, and it gives the PDF section more substance than a collection of convenience tricks.
Switching to images reveals another surprisingly broad collection of capabilities. One-click background removal, manual color selection with the Instant Alpha-style tool, subject copying, clipboard-based document creation and simple collages are demonstrated rapidly but clearly. Preview's resize controls and estimated resulting file size are especially practical for everyday situations where an image needs to meet an upload limit, while the exposure and contrast controls show that basic image adjustment is possible without presenting Preview as a replacement for a dedicated photo editor.
The presentation also does a good job acknowledging Preview's less intuitive behavior. PDFs and images operate differently enough that directly pasting an image onto a PDF does not work as expected, leading to the strange workaround of pasting the image onto itself before copying that result into the PDF. Similarly, image edits are described as effectively baked in after saving and closing before the presenter introduces Preview's stored document versions as a recovery option. These quirks are useful discoveries, although some would benefit from slower explanation because the brisk pace occasionally turns unusual behavior into a trick to memorize rather than something viewers will fully understand.
Privacy and document metadata provide another worthwhile layer. The info pane is shown exposing creator information, application details, annotations and potentially photo location data, with options demonstrated for removing location metadata and managing annotations. The qualification that generative-AI editing information appears only when the editing application embeds it is important. More broadly, this section effectively reminds viewers that a file can contain information beyond what is visibly displayed, although the rapid sequence leaves little time to explore exactly which metadata survives different export or conversion methods.
Preview's more obscure capabilities make the latter portion entertaining, particularly support for numerous file formats, batch operations on folders and the hidden export formats revealed by holding Option. The 3D-model demonstration is the biggest surprise, extending beyond viewing into moving, rotating and resizing objects, adjusting lighting, inspecting camera views and rendering the scene. The presenter does not pretend every feature will be broadly useful, and the joke about obscure export formats keeps this denser material moving without overselling its everyday relevance.
Toolbar customization brings the focus back to features that could genuinely improve routine use. Faster page skimming, navigation history and direct page-number entry are sensible additions that make large PDFs easier to navigate, while canvas-color customization and the dark PDF appearance demonstrate that even Preview's viewing environment has more flexibility than its default configuration suggests. The closing Apple Notes integration is comparatively brief and doubles as a transition toward another video, but it does not substantially distract from a tutorial that remains densely packed with useful demonstrations.
Pros
- PDF rearranging, extraction and merging are demonstrated through clear, immediately usable examples.
- The redaction section highlights an important difference between visually covering sensitive material and actually removing its underlying content.
- Image tools cover an unexpectedly useful range of background removal, resizing, basic adjustments, subject extraction and simple compositing.
- Metadata and location-information demonstrations add a valuable privacy dimension to the tutorial.
- Batch processing, expanded export formats and 3D-model support effectively demonstrate Preview's breadth beyond PDFs and ordinary images.
- Toolbar customization offers practical improvements for navigating large documents.
- The energetic presentation keeps more than 30 features moving without becoming a dry menu-by-menu walkthrough.
Cons
- The rapid pace gives some unusual features and workarounds little explanation beyond the steps needed to reproduce them.
- The image-to-PDF paste workaround is cumbersome and illustrates how inconsistently Preview's separate editing modes can interact.
- Several specialized capabilities, particularly 3D editing and obscure export formats, are demonstrated without enough context to establish how useful they are in typical workflows.
- Metadata behavior is introduced effectively but not explored deeply enough to clarify what different saving, exporting or conversion methods preserve.
Preview emerges as a much broader Mac utility than its understated interface initially suggests, with particularly useful strengths in PDF manipulation, image handling, batch processing and document privacy. The presentation occasionally moves too quickly through the stranger details, but its combination of practical shortcuts and genuinely unexpected capabilities makes it an unusually productive software tutorial.
