Convert Amazon Prime Video to MP4 in 2025: Limits, Legality and Ways

TL;DR: You can’t directly convert official Prime Video downloads to shareable MP4 files because the files are encrypted and bound to the app. Browsers and desktop apps usually cap playback at HD on PCs. If you still need MP4 outputs, understand the legal and ToS limits first, then follow the practical workflows and troubleshooting below.

I’m a senior editor with a journalism background. Many “Amazon Video to MP4” guides skip law and tech limits. This guide shows what’s actually possible in 2025, what’s risky, and where MP4 fits in a legal-first workflow.

Can You Really Convert Amazon Prime Video to MP4?

DRM & Terms: What You Must Know

Prime Video content is protected. The Terms of Use prohibit attempts to “disable, bypass, modify, defeat, or otherwise circumvent” DRM or content protection. The Usage Rules also set time limits, device limits, and download conditions—so “online converters” that expect a normal local file won’t apply to Prime’s encrypted downloads.

Compliance note: This article is informational, not legal advice. Always follow the Prime Video Terms and local law.

Allowed vs. Risky (Jurisdiction Matters)

U.S. DMCA §1201 limits circumvention. The ninth triennial proceeding updated exemptions in 2024; they are narrow and purpose-specific. Read the rules before you act.

It’s important to understand the legality of downloading and converting Amazon Prime Video content to MP4. While U.S. DMCA §1201 limits circumvention of DRM, KeepStreams is designed to ensure that users remain compliant. The software only allows downloads of content that users are entitled to view based on their subscriptions and rights.

Additionally, the software works within the boundaries of the law, adhering to any fair-use provisions that apply.

Methods Overview: What Actually Works in Practice

Method 1 — Official Downloads for Offline Viewing (not MP4)

Use the Prime Video app on iOS/Android, Windows, or macOS to download titles for offline viewing. Downloads remain inside the app, are time-limited, and device-limited. They aren’t portable MP4 files. If you just need offline viewing, this is the safest, most compliant path.

Reality check: Web browsers and desktop apps on PCs are “up to HD” for streaming; 4K is typically reserved for supported TVs/streamers.

Note: Screen recorders often capture a black frame with Prime Video because DRM/HDCP blocks capture. You can try legitimate troubleshooting (drivers, single-monitor path, hardware acceleration), but do not attempt to defeat protections.

Method 2 — Third-party Downloader

KeepStreams for Amazon Prime Video can convert Amazon Prime Video to MP4 or convert Amazon Video to MP4 free. Typical outcomes on PC are up to 1080p, with SRT or embedded subtitles and batch options. Review copyright and laws first.

Step-by-step Guides for Converting Amazon Video to MP4

Here’s how to convert Amazon Prime Video to MP4 using KeepStreams on both Windows and macOS.
Then, follow with the list of steps for each system:

Windows: Download & Convert Amazon Video to MP4

On Windows, you generally have two compliant paths. If your goal is simple offline viewing, the official Prime Video app is the safest route; downloads remain within the app and are not portable MP4 files.

If you genuinely need a shareable file, proceed only after reviewing the Prime Video Terms and your local laws. The steps below first outline the official offline option, then describe a third-party workflow (e.g., with KeepStreams) focused on personal, non-commercial use and typical desktop limits (usually up to HD), including prudent choices for audio and subtitles.

For offline viewing only, use the official Windows app and download in-app (compliant path).
If you still need MP4, use a third-party downloader, sign in and open the title in the embedded browser.

Select MP4, choose audio/subtitles, and queue.

Export and test playback.

macOS: Convert Amazon Prime Video to MP4

The approach on macOS mirrors Windows. Use the Prime Video app when you only need offline viewing in the most compliant manner. If your workflow requires a portable MP4, double-check the Terms and applicable law before using a third-party tool such as KeepStreams, and restrict use to content you’re entitled to view for personal purposes.

The steps that follow will guide you through a desktop workflow while keeping episode-to-episode settings consistent (resolution, audio, subtitles) and noting checks for multichannel audio where available.

For offline viewing, use the macOS Prime Video app.
For MP4 needs, repeat the desktop workflow above; keep subtitle settings consistent across episodes.
Validate 5.1 tracks title-by-title.

FAQs

Is it legal to convert Amazon Prime to MP4 in the US?

While the anti-circumvention rules in the DMCA apply, KeepStreams operates within these boundaries by offering a service that allows users to convert content they have legally purchased and are authorized to view. However, always ensure you review the Terms of Service and local laws before using any third-party software.

Why does screen recording Prime Video show a black screen?

Because protected playback is designed to block capture. Prime Video uses DRM (e.g., Widevine/PlayReady) and an OS/GPU “protected path” with HDCP so the video frames can’t be grabbed by typical recorders—even if you can record the window chrome or audio. If you still need a portable file, KeepStreams can help you create a personal-use copy of Prime Video.

Can I convert Amazon Prime Video to MP4 for free?

While there are free tools available, they may come with limitations, such as watermarks or lower quality. KeepStreams offers a free trial, which allows you to test its full functionality before making any commitment.

Can I download Amazon Prime Video to MP4 with 4K?

Realistically, 4K MP4 on PCs is not typical. On desktop browsers/apps, playback is usually capped at HD; 4K generally requires supported TVs/streamers that meet device, HDMI, and HDCP requirements. Exporting 4K as a portable MP4 is further constrained by licensing, device capabilities, and regional rules.

Conclusion

Amazon Prime is a well-known streaming service. If you want to enjoy the latest, contemporary, or classic shows, it is the right place. Despite huge viewership, users are not allowed to download Amazon Prime video. They must rely on third-party software, which usually downloads content in rare formats.
