How to zip a file on any device in 2026

If you use a computer for more than five minutes a day, you’ve met the ZIP file, even if you never gave it much thought. It’s the boring hero behind “here’s the whole project folder,” the fix for “attachment too large,” and the reason you can send someone 60 assets without blowing up their inbox.

The basic idea is simple. A ZIP file is a container that holds one or more files and folders, and applies lossless compression to them on the way in. Text-heavy content, spreadsheets, code and logs usually shrink nicely. Photos, music and video often don’t, because they’re already compressed. You still get the convenience of one tidy package, but not always a dramatic size cut.

That’s where the built-in zipping tools in Windows, macOS and mobile OSes come in, and where something like Documents.io earns its keep when you really need to shrink things down.

Windows: zipping files and folders the easy way

On Windows 10 and Windows 11, zipping is built right into File Explorer. Find the file you want to compress, right-click it and choose “Send to”, then “Compressed (zipped) folder”. Windows drops a new .zip file in the same folder, leaving the original untouched.

The same move works for entire folders. If you need to send someone a project directory rather than a single file, right-click the folder instead. Explorer bundles everything inside into a single archive, including subfolders, so the recipient can unzip it and see the same structure you see locally. It’s a neat answer to the “I need to compress a folder” problem without introducing any new tools.

Zipping several files at once is just as simple. Select them in File Explorer, either with Ctrl for individual picks or Shift for a range, and run that same “Send to → Compressed (zipped) folder” command. You end up with one archive that’s perfect as an email attachment or cloud upload, instead of a scatter of individual files.

Windows 11 has quietly become friendlier to archives in general. Recent builds can open formats like RAR and 7z as well as ZIP, although you still need specialist software if you care about encrypted archives or niche formats. For most day-to-day use cases, the built-in ZIP support is enough.
macOS: compression hiding in Finder

macOS: compression hiding in Finder

On a Mac, the compression story lives inside Finder. Control-click or right-click any file and choose “Compress”. macOS instantly generates a new file with the same name and a .zip extension, in the same folder.

If you compress a folder, everything inside it comes along for the ride, which is the Mac equivalent of zipping a folder or a whole batch of assets for a project. When you select multiple files at once and compress them, macOS creates an archive called Archive.zip, again right next to the originals. You can rename it like anything else.

In practice, that one Compress command covers all the common “how do I create a ZIP on Mac?” scenarios: a single file, a folder full of resources, or a hand-picked set of items you’ve selected in Finder.

Doing it on your phone: Android and iOS

The days when you had to wait until you got back to a laptop to compress something are over. On Android, the Files by Google app can bundle things up. You select one or more files or folders, tap the menu button and choose to compress them; the app spits out a ZIP you can share straight into email, messaging apps or cloud storage.

On iPhone and iPad, Apple’s Files app plays the same role. Navigate to a folder, tap Select, choose whatever you want to bundle, hit the more icon and tap Compress. A ZIP archive appears in the same location, ready to send. For quick one-off jobs like mailing a bunch of images or exporting a notes folder, it’s much faster than juggling desktop tools.

When zipping isn’t enough: enter Documents.io

There’s a catch with ZIP that you only really notice when you’re dealing with big PDFs, slide decks or video. Zipping those files often doesn’t change the size much at all. The formats themselves already use compression, so there’s not much left for ZIP to squeeze.

That’s when it makes sense to use something more specialised, and this is where you can lean on Documents.io instead of just creating another archive. Documents.io runs entirely in the browser and focuses on compressing the file types that are painful to move around: PDFs, images, audio and video. 

You upload a file, choose how aggressively you want to compress it, and download a smaller version that’s still usable. 

Because it lives on the web, it doesn’t matter whether you’re on Windows, macOS, Linux or a locked-down work machine. The same site also handles a long list of conversions, so you can turn a Word document into a PDF, or even convert between different media formats before you compress them. The platform groups everything into three main families: converters, compressors and file transfer tools, so you’re not hunting through a maze of separate services. 

There’s a generous on-ramp, too. Documents.io offers a period of full, unlimited access to all of its tools, then settles into a free tier with a set number of actions per day. If you discover that you’re regularly shrinking large PDFs, media files or archive-format documents, there’s a paid plan that unlocks higher limits and larger maximum file sizes. 

If you live on your phone or tablet, the companion Documents app for iOS and iPadOS plugs into the same ecosystem. It acts as a full-blown file manager on mobile, can compress PDFs and other big files locally, and syncs easily with cloud services like iCloud or Dropbox. It’s a neat way to do serious compression work without ever leaving your iPad. 

A smart workflow in 2026 often looks like this: use Documents.io to shrink the heavy hitters in your project – the 90-page PDF, the product video, the giant image assets – then zip the result together with the rest of your files so you have one clean archive to send or upload.

Do you still need dedicated ZIP software?

For most people, the answer is probably not. The built-in tools in Windows, macOS, Android and iOS, plus a browser-based service like Documents.io for serious compression, cover almost every everyday job.

If you live in a more technical world, there is still a place for dedicated archivers. Open-source tools like 7-Zip and PeaZip handle a huge range of archive formats, offer strong encryption and advanced options, and are free to use. On modern Windows 11 systems, NanaZip gives you that same 7-Zip engine in a more native-feeling interface. But these are power user tools; they’re overkill if all you want to do is send a zipped-up folder of assets once a week. 

For everyone else, the modern playbook is simple. Zip files when you want to bundle and organise things; reach for Documents.io when you actually need to make those things smaller. Between the two, you avoid the worst of “attachment too large,” without turning basic file sharing into a part-time job.
