Ninja Download Manager does its job on Windows. But if you need to download files across devices, browsers, and operating systems without installing software, FileGrab is the better answer.
Understanding what Ninja DM offers helps clarify where FileGrab is the stronger choice.
Ninja Download Manager is a Windows desktop application with a companion browser extension for Chrome. When you click a download link in Chrome, Ninja DM intercepts it and manages the download through its own queue — supporting multi-segment downloading for faster transfer speeds on single large files.
It also includes a scheduler for timed downloads, a speed limiter, and basic download history. Some users appreciate the ability to pause and resume downloads reliably, particularly on slower or unstable connections.
However, Ninja DM is Windows-only, requires a desktop installation and a Chrome extension, and provides no meaningful way to scan a webpage for all its downloadable files.
FileGrab is purpose-built for web-based file discovery and bulk downloading. You paste a URL, our server scans the page, and you get a complete list of every downloadable file on it — with names, types, and sizes — before downloading anything.
This is the use case Ninja DM doesn't cover well. It can intercept downloads as you click them, but it won't proactively surface all the PDFs on a page, or let you batch-select 20 images and download them as a ZIP.
FileGrab also works on Windows, Mac, Linux, iOS, and Android — in any browser — without a single installation.

Note: For users who specifically need multi-segment download acceleration for very large single files, Ninja DM and similar tools still have a role. FileGrab excels at web page file discovery and bulk downloading.
Desktop download managers made sense when browsers were slow and unreliable. Modern browsers and server-side tools have changed the equation.
No install, no setup, no license key. Open filegrab.io and you're downloading within seconds.
FileGrab is updated server-side. You never have a version mismatch, a broken extension, or an outdated browser plugin.
One URL. Works on every device and OS you own — your Windows desktop, MacBook, Android phone, and iPad all use the same tool.
No downloaded executable, no DLL files, no background service running on your machine. FileGrab runs in your browser's security sandbox.
FileGrab proactively surfaces all files on a page — you don't have to find and click each link. That's the capability desktop managers have never offered well.
A free tier that's genuinely useful, and Pro pricing that's clearly laid out. No nag screens, no trial countdowns.
Switching takes about two minutes. No uninstaller wizard required (though you can uninstall Ninja DM if you want to).
Sign up with an email and password. Your free account comes with 20 scanning credits — no credit card needed to start.
This can be a documentation page, a blog with downloadable resources, a file hosting page — any publicly accessible URL with linked files.
Hit Scan. In a few seconds, you'll see a list of every downloadable file on that page — with file type and size shown for each.
Click individual files to download them, or select multiple and export a ZIP (Pro). That's the full workflow — nothing else to configure.
If you no longer need multi-segment acceleration for large single files, you can uninstall Ninja DM entirely. FileGrab covers everything else.

Ninja Download Manager (Ninja DM) is a Windows download manager and browser extension that accelerates and organizes file downloads. It integrates with Chrome and other browsers to intercept downloads and manage them through its own queue system.
If you're primarily using Ninja DM to download files from web pages — rather than accelerating very large single-file downloads — FileGrab covers that use case without any Windows installation. FileGrab also works on Mac, Linux, and mobile, while Ninja DM is Windows-only.
FileGrab's primary value is server-side page scanning and bulk file discovery. For most users, the perceived speed is faster than traditional download managers because FileGrab fetches and packages files server-side at data-center network speeds. It does not split single-file downloads into segments for acceleration.
You need a free account to use FileGrab — it takes under a minute to sign up with an email and password. Your account stores your scan history so you can re-run scans and track what you've downloaded.
Yes — fully. FileGrab works on iOS and Android in any mobile browser. Ninja Download Manager has no mobile equivalent. For mobile file downloading, FileGrab is the clear choice.
Free tier available — 20 scans, no credit card, no install, no Windows required.
