Preview

Preview comes pre-installed on every Mac. It handles PDFs, images, and even basic editing — all without downloading anything extra. For most Mac users, this Preview review will confirm what you probably already suspect: it does more than you think. Whether you're signing a document, cropping a photo, or merging PDFs, Preview gets the job done fast. This Preview review covers everything you need to know about Apple's quietly powerful built-in tool.

Key Features

• PDF Annotation — Highlight text, add notes, draw shapes, and mark up documents directly inside Preview. No third-party app needed.
• Image Editing — Crop, resize, rotate, adjust color, and remove backgrounds from common image formats like JPEG, PNG, TIFF, and HEIC.
• Form Filling & Signatures — Fill out PDF forms and add your signature using your trackpad, camera, or iPhone. Signatures save for reuse across multiple documents.
• Batch File Conversion — Convert multiple images or PDFs at once to different formats like PNG, JPEG, or PDF. Saves time on repetitive tasks.
• Side-by-Side Comparison — Open multiple images or PDFs in a split view to compare files quickly without switching windows.
• Password Protection — Lock PDF files with a password directly from the export menu. No extra tools required.
• Thumbnail Sidebar — View all pages of a PDF in a sidebar panel. Drag and drop pages to reorder them or delete individual pages with ease.
• Markup Tools — Use the built-in Markup toolbar to add text boxes, speech bubbles, arrows, and freehand sketches to images and PDFs.
• Color Adjustment — Adjust exposure, contrast, saturation, sharpness, and white balance on images using the built-in color tools.

User Experience

Preview has a native Mac interface that feels clean and fast. There's no learning curve for basic tasks — open a file and the tools are right there. The toolbar is customizable, so you can keep only what you use. It's beginner-friendly but also works well for power users doing quick edits.

Opening files is instant. PDFs load smoothly even when they have many pages. Images render sharply and respond quickly to edits. The Markup toolbar slides in without cluttering the interface. For day-to-day tasks like reviewing a contract, resizing a photo, or signing a form, Preview rarely gives you a reason to open anything else.

The app also handles multiple open files well. You can have several documents open in tabs or separate windows. The Contact Sheet view lets you browse image thumbnails in a folder quickly, which is useful for sorting through batches of photos or scanned documents.

At the time of writing this article, Preview is completely free. It comes pre-installed on every Mac at no cost. There is no subscription, no in-app purchases, and no premium tier. Prices are subject to change, so check the official Apple website for current pricing and any available sales.

Affinity Photo

Affinity Photo is a full image editor with layer support, RAW editing, and professional tools. It goes far beyond what Preview offers for photo editing. It's a paid app, but a good option if you regularly need more than basic adjustments.

Skim

Is This Preview Review Right for You?

Preview works well for a wide range of users. If you mainly open PDFs, sign forms, annotate documents, or do light image editing, Preview covers all of that without installing anything. It's especially useful for students, remote workers, and anyone who regularly handles scanned documents or downloaded PDFs.

If your work involves detailed photo retouching, vector design, or editing the actual text content inside a PDF, you'll likely need a dedicated app. But for the majority of everyday tasks on a Mac, Preview handles them without friction. It's one of those apps that's easy to overlook because it's always been there — but once you explore what it can do, it becomes a regular part of your workflow.

Conclusion

This Preview review shows that Apple's built-in app is a solid, reliable tool for everyday Mac users. It handles PDFs and images with ease, costs nothing, and requires no setup. If you need advanced editing or cloud sync, you may want a dedicated app — but for most daily tasks, Preview delivers without getting in your way.
