- QuickLook brings to Windows Instant preview with the space bar and wide format compatibility.
- It is installed from the Microsoft Store or GitHub and is powered by plugins such as OfficeViewer, FFmpeg, and EpubViewer.
- On macOS, Quick Look lets you rotate, crop, and use Bookmark; on Windows, Peek is rumored to work with Shift+Space.
Windows Explorer has included a preview pane for years, but its scope is limited and, aside from images, falls short when we want to quickly check the actual contents of a file. The idea of pressing a key and instantly viewing a document, spreadsheet, PDF , ZIP, or even a GIF without opening anything sounds like science fiction in Windows… until you try QuickLook.
QuickLook brings a popular macOS feature to Windows: instant previews at a convenient size without leaving the file list. It's a free and open-source project that integrates with File Explorer , allowing you to quickly and easily check if a file is the one you're looking for, which application can open it, or whether it's worth continuing to view it, saving you countless hours every day.
What is QuickLook and what does it offer?

QuickLook was created with a very specific mission: to bring macOS's quick preview functionality to Windows with minimal setup and straightforward usability. Compared to similar alternatives like Seer, which has been discussed in tech publications, QuickLook stands out for being completely free and not reserving updates or improvements for paying users, making it particularly appealing.
The project evolves frequently and has received updates since its initial builds. Version 0.1.10 was cited as one of its recent releases ; the important thing is that development is ongoing and, due to its open nature, any user can review the code or collaborate via GitHub whenever needed.
The philosophy behind it is simple: you select a file in Explorer and get a floating preview that doesn't interrupt your workflow. This window lets you navigate, zoom, and even play audio and video if the format is supported, so you can inspect the essentials before opening or discarding it.
In terms of compatibility, QuickLook is surprisingly comprehensive, because it not only covers the basics but also expands its capabilities with plugins. Out of the box, it can handle images, text files, PDFs, Office documents, video, HTML, and Markdown, as well as ZIP and other compressed files , and with plugins, it can support even more formats.
- Images: PNG, APNG, JPG/JPEG, BMP, GIF and PSD.
- Documents and data: TXT, PDF, CSV and Office documents (DOC, DOCX, XLS, XLSX, PPT, PPTX).
- Video and audio: MP4, MKV, M2TS, MOV, AVI, WMV, MP3 and M4A (autoplay in preview when applicable).
- Web and markup: HTML and Markdown.
- Pills: ZIP, RAR and 7Z (with the possibility of taking a look at their contents).
A key difference from other approaches is that QuickLook is not intended to replace your programs; its goal is to inspect quickly and without distractions , just enough to confirm if that file is the correct one or which one weighs the most among several options in your folder.
How to use it in Windows Explorer

The key action is incredibly easy: select a file and press the spacebar. With Space, you can instantly open and close the preview window , without switching applications or opening resource-intensive editors, and without leaving Windows Explorer.
To move between items without closing the preview, use the arrow keys to go to the previous or next file . It's a quick way to browse through a folder full of documents, photos, or videos without opening them one by one.
If you need to see a detail clearly, you can zoom in using CTRL + mouse wheel . This is incredibly useful with images, PDFs, or presentations, where sometimes a small detail makes all the difference.
With compatible audio and video clips, QuickLook includes its own player. Media automatically starts playing in the preview window , so you can quickly listen to or watch content without launching your usual player.
In the case of Office documents, there's a nuance to keep in mind: with the basic installation, you might only see metadata such as file type, size, or name . To view the actual content of the DOCX, XLSX, or PPTX file, you should activate the appropriate plugin (we'll cover this in the Installation and Add-ons section below; if you encounter an error, see how to troubleshoot preview handlers ).
With ZIP, RAR, and 7Z compressed files, QuickLook lets you inspect their contents with the press of a spacebar. Exploring the contents without unzipping avoids opening file managers or wasting time , especially when you just need to confirm if that PDF or folder you're looking for is inside.
Download and install: Microsoft Store, GitHub, and essential plugins

There are two clear ways to get QuickLook up and running: the Microsoft Store and GitHub. Both are official and straightforward ; the Store is more direct for most users, and GitHub is ideal if you want plugins and releases readily available.
Installation from Microsoft Store (application published by Paddy Xu): This is the most convenient option and weighs around 60 MB , so the download and deployment are very fast on almost any current computer.
- Open Microsoft Store and search for "QuickLook" (make sure you choose the "QuickLook" publication). Paddy Xu).
- Click "Get" to download and install. It'll be ready in a few moments.
- Open Explorer, select a file, and press the spacebar to preview it.
If you prefer GitHub or don't see the app in the App Store, the alternative is equally simple. GitHub hosts the project's official installer and plugins , as well as its version history.
- Visit QuickLook's GitHub page and go to "Releases" (select the latest available version).
- Navigate to the artifacts and download the file . MSI. After downloading, run the installer.
- Go back to the repository and open the section plugins to expand format compatibility.
Among the most useful add-ins are OfficeViewer (for viewing the actual content of Office documents), FFmpeg (which expands multimedia codecs), and FontViewer (font preview). Install them by downloading the packages from the official links and following the instructions.
Pro tip: If you're previewing an Office file and only see basic information, QuickLook might display a button in the window that says "Click here to install this plugin ." Click it to install the plugin, and then restart QuickLook. From then on, you'll be able to read Word , Excel, and PowerPoint files without opening their native programs, even if you don't have Microsoft Office installed.
Beyond Office, the plugin ecosystem is growing to meet specific needs: EpubViewer adds support for ebooks (EPUB) , there are extensions for 3D models, Android APK packages , folders, shape files, and much more. If your workflow involves unusual formats, take a look because there's probably a plugin that can handle it.
When closing the loop, don't forget about file compatibility. With QuickLook, you can view the internal structure of a ZIP or 7Z file directly from File Explorer; ideal for verifying that the file contains exactly what you need before extracting it.
Quick Look on macOS, extensions, and the future of Windows

Those coming from Mac will already be very familiar with this feature: Quick Look in macOS offers a wide, high-quality preview of almost any file with just a press of the space bar. From there, you can even perform small actions without opening resource-intensive apps.
On macOS, for example, you can rotate photos, trim audio or video clips, and use Markup directly within the Quick Look window. For those who manage large media libraries, this flexibility saves countless clicks and waiting times.
Another interesting detail is that of Live Photos on Mac: when you open one in Quick Look, the video portion plays automatically ; if you want to watch it again, simply press the "Live Photo" control that appears in the lower left corner.
In addition to the base system, there are extensions that take Quick Look a step further. There's a macOS extension that lets you instantly browse folders and compressed files without opening or decompressing them , available for free on the Mac App Store. This type of add-on demonstrates how powerful the concept is when it's shared with the community.
What about Windows? There's been talk for some time about integrating a similar feature into the system, codenamed Peek . According to the information shared, the idea would be to preview files using the Shift + Space combination , with a lightweight window focused on checking PDFs, Excel spreadsheets, Word documents, images, videos, audio, and more. There's also been talk of possible integration with the Photos app for a more cohesive experience, although it's unclear whether it will cover as many multimedia formats as on Mac from day one.
Another piece of good news for productivity in Windows is tabbed browsing in File Explorer. The ability to open multiple folders in tabs makes moving and copying files easier , and, combined with instant preview, paints a very promising picture for users with file-intensive workflows.
Returning to the comparison of solutions, specialized media outlets have discussed alternatives like Seer and recommended similar desktop utilities. Headset has even been cited as a mini-player that transforms YouTube into a desktop music app , a sign that the ecosystem of lightweight, productivity-focused tools has been growing and connecting the pieces for some time.
In terms of limitations and extensions, it's worth remembering that the basic QuickLook doesn't cover every conceivable format . For example, it doesn't open ebooks by default, but installing the EpubViewer plugin solves this problem instantly. Similarly, extensions like FFmpeg open the door to more video and audio codecs, and FontViewer shows you fonts directly from your folders.
If your daily work involves reviewing large batches of files (design projects, photo archives, reports, scanned receipts, etc.), the combination of ultra-fast previews, keyboard shortcuts , and extensible compatibility represents a significant leap forward compared to the Windows Explorer sidebar. It's not that the latter is useless; it's just that QuickLook addresses a different need: making decisions in seconds without opening anything else.
In case you're wondering: it runs in the background, which is lightweight . After installing QuickLook, it's best to launch it once to activate it; you'll see its icon in the notification area (next to the clock). From that moment on, it will be ready to respond to your spacebar in any folder, whether local, network, or even external drives.
It's also worth adjusting your expectations. The preview doesn't replace an editor, nor does it cover advanced features : if you need to edit, sign, add in-depth comments, or export, you'll have to open the corresponding application. QuickLook is the preview filter that eliminates that step when you just want to confirm something, and in that respect, it's absolutely unbeatable in speed.
Finally, keep in mind that QuickLook is open-source software and constantly evolving . This means that compatibility and performance may vary slightly depending on the version and installed plugins. If something isn't working as expected, checking the latest releases on GitHub and its issues section usually resolves the issue quickly.
With all of the above in mind, it's clear that QuickLook fits perfectly into the modern file workflow: less friction, less waiting, and a preview accurate enough to make decisions without loading entire applications. Add to that the plugins, support for compressed files, and navigation shortcuts, and the increased efficiency is noticeable from day one, especially for those who live surrounded by overflowing folders.
