4K Video Downloader Supported Sites: 10 Tools Compared (2026)

A 4K video downloader supported sites list can look reassuring until a listed service stops working after a site update. The practical answer is to compare current status, source-native resolution, output format, and device fit, then choose a downloader, recorder, or editor for the actual job.

This guide compares ten options without treating every 4K download software claim as equal. My rule is simple: confirm the exact site and source quality first, because a 4K label cannot create detail the source does not provide.

What 4K Video Downloading Means

To download 4K video in source-native quality, a tool must receive a genuine 4K source and save a compatible stream. Screen recording, editing, AI upscaling, and lower-resolution M3U8 downloading are different workflows, even when the resulting file can be displayed on a 4K screen.

• Source-native download: saves the resolution and streams made available by the site.
• Screen recording: captures playback and depends on display, app, and recording settings.
• Editing: trims or exports a file that already exists; it does not fetch a video from a supported-site URL.
• Upscaling: increases output dimensions but does not restore source detail that was never present.

In my view, the method matters more than a headline 4K video software label. If a site exposes 1080p to a particular workflow, selecting 4K output does not turn that source into native 4K.

4K Video Downloader Selection Essentials

Choose 4K download software by checking the exact site, current operation, source quality, output, device support, limits, and maintenance. A best 4K video downloader for PC claim means little if the service, title, or codec you need is unsupported.

Before comparing apps, confirm these prerequisites:

• You can access the video through an authorized account or a public page.
• The source title is actually offered in 4K for your plan, region, and device path.
• Your playback device supports the selected container and codec.
• You have enough local storage for large source-quality files.

Use this five-step check before installing a tool:

1. Find the exact site in the product's support information, then check whether that site is working now.
2. Confirm whether the method downloads, records, edits, or upscales video.
3. Match the native app to Windows, macOS, Linux, iPhone, iPad, or Android.
4. Check source resolution, MP4 or MKV output, audio, and subtitle handling.
5. Compare trial limits, batch behavior, scheduled tasks, and update cadence.

Source Quality and Resolution

Source-native resolution is the first filter. A downloader can offer a 4K setting only when the site, title, account, region, and available stream support it; otherwise the practical ceiling is lower.

Lowering resolution reduces pixel detail, even if the smaller file looks acceptable on a compact screen. I would choose the native stream that fits the intended display rather than chase a larger label.

Device and OS Compatibility

A 4K video downloader for PC is usually a native desktop app, while a 4K video downloader for iPhone or a 4K video downloader for iPad may actually describe recording, editing, or file-transfer steps. Those are separate compatibility questions.

Windows and macOS support does not imply a native mobile app. For phones and tablets, check whether the workflow happens on-device or whether files are created on a computer and transferred afterward.

Pricing and Trial Limits

Trials are useful only when they cover the site, title, and output you plan to use. Compare download counts, service-specific limits, refund conditions, and whether the advertised price belongs to one module or a multi-product suite.

As of August 2026, KeepStreams One lists $69.99 mo., $169.99 yr., and $269.99 Lifetime. These are suite prices, not the standalone KeepStreams M3U8 Downloader price. Its 30-day trial allows three videos per streaming service; those figures describe the suite offer and should not be read as the M3U8 module's standalone price.

Output Formats and Codecs

MP4 and MKV are containers, not quality guarantees. Their availability depends on the video, audio, subtitle, and codec combinations exposed by the source, so the same site may not offer identical choices for every title.

MP4 is widely convenient, while MKV can be a better fit when multiple tracks or subtitle combinations need to stay together. The practical choice is the format your playback setup can handle without extra conversion.

Batch, Subtitle, and Update Features

Features matter when they reduce repeat work or preserve the parts of a stream you need. Useful checks include batch queues, scheduled episodes, selectable audio, embedded or external subtitles, resource use, and a visible update cadence.

• Best for recurring series tasks: a maintained downloader with queues and subtitle controls.
• Not ideal for occasional clips: a large suite whose extra modules do not match the job. Current compatibility and method fit are better filters than a generic 4K claim.

Supported Sites and Current Status

Official support and current operation are different signals. The matrix below separates site coverage from method, quality, device workflow, and operating status, using a single August 2026 snapshot rather than assuming a listed site works for every title.

A reader who needs direct URL downloads should start with an active downloader and its exact supported-site list. Recording fits services without a stable download route, while editing tools fit files already on the device. A 4K video downloader for Netflix also requires title, plan, region, and source-resolution checks rather than a platform-name assumption.

10 4K Video Tools Compared

These ten options cover direct download, playback recording, mobile capture, editing, discontinued software, and tools with unknown status. I would shortlist by task first. That prevents a polished editor from being mistaken for a site-compatible downloader.

KeepStreams M3U8 Downloader (Windows and Mac)

For personal offline viewing of content you're authorized to access, where permitted by platform terms and applicable law, KeepStreams M3U8 Downloader provides a Windows and macOS workflow for 900+ M3U8 sites with output up to 1080p in MP4 or MKV.

Batch queues, scheduled episodes, selectable audio, and embedded or external subtitles make it a fit for recurring M3U8 series work. It is not ideal when source-native 4K is the deciding requirement. KeepStreams is designed for content available through an active subscription or authorized account, not content outside that access.

The workflow is straightforward:

1. Download and install KeepStreams from its official website.
2. Enter the URL, or open the relevant service under VIP Services.
3. Play the video and wait for analysis; if it does not start, select the orange download button.
4. Choose the available output format and track options in the settings window.
5. Open Downloads to view progress, speed, and completed files. 

Platform availability may change, so check the service's current status before building a large queue.

StreamGaGa Video Downloader (Windows and Mac)

StreamGaGa Video Downloader remains an active Windows and Mac desktop downloader for multiple streaming sites. Its available quality and output depend on the service and source title, so it should not be treated as a universal 4K route.

• Best for multi-site desktop workflows: users who want one interface for several services.
• Not ideal for: readers choosing solely from a broad maximum-resolution claim without checking the exact site.

Audials One 2026 (Windows)

Audials One 2026 is a Windows recording-focused workflow, not a direct supported-sites downloader. It records playback, so completion time and output depend on the playback and recording setup rather than a downloadable source stream.

• Best for recording-led Windows tasks: cases where playback capture is acceptable.
• Not ideal for: readers who want a direct source file, selectable source tracks, or a workflow that finishes faster than playback.

RedFox AnyStream (Discontinued)

RedFox AnyStream went offline in June 2024 and is now a discontinued product. It is not an active peer with current pricing, support, or a maintenance path for new users.

The practical choice is an active tool covered in this comparison. I would not build a new workflow around software whose service is offline.

4K Video Downloader Plus

4K Video Downloader Plus is an active URL-based downloader that lists sites such as YouTube, Facebook, and Vimeo. The exact format and resolution still depend on the source and current site integration.

• Best for direct public-video URLs: a familiar paste-and-download workflow.
• Not ideal for: assuming that every listed site or title exposes native 4K. A focused 4K Video Downloader Review helps frame its compatibility and workflow limits without turning one successful site into a blanket promise.

Y2Mate M3U8 Downloader (Windows)

Y2Mate M3U8 Downloader currently lists Windows 11/10 support and output up to 1080p for M3U8 or HLS workflows. It is not a native Mac app and should not be selected for a source-native 4K requirement.

• Best for Windows M3U8 tasks: users whose source and output needs fit the stated ceiling.
• Not ideal for: Mac or native 4K workflows. The Y2Mate M3U8 Downloader review therefore fits readers comparing this specific Windows route.

FreeRapid Downloader (Status Unknown)

FreeRapid Downloader's current operating status, platform support, 4K capability, and price are unknown. It should not anchor a new workflow that depends on maintained site integrations.

• Best for: historical comparison only.
• Not ideal for: current purchasing or compatibility decisions.

iMovie (Editing Fallback)

iMovie is Apple's video creation and editing app for Mac, iPhone, and iPad. It can edit and export 4K projects when the source and device support that workflow, but it does not download videos from a supported-sites list.

Best for Apple-device editing: trimming and exporting video already available to the app. Not ideal for: readers who want to paste a site URL and retrieve a downloadable source file.

iPhone Screen Recorder (Status Unknown)

This unidentified iPhone and iPad entry is a recording fallback, not a site-compatible downloader. Its exact current App Store listing and price are unknown, so it should not anchor a purchase decision.

Best for: permitted on-device capture when recording is acceptable. Not ideal for: readers who need source files, a verified supported-site list, or documented current product support.

XRecorder (Android Recording Fallback)

XRecorder is an Android screen recorder rather than a site-compatible video downloader. Recording quality depends on the device, source playback, and chosen settings, so it should not be presented as proof of source-native 4K.

Best for Android recording: permitted captures when a direct file is unnecessary. Not ideal for: readers who need original downloadable files from a 4K video downloader supported sites list.

FAQs and Download Failures

Supported-site failures usually come from a changed site, access state, region, source title, or outdated integration. Work through the checks in order instead of assuming the entire 4K Downloads software category is broken.

Why can a listed supported site stop working?

A support list describes intended compatibility, not a promise for every moment or title. Site changes, app updates, sign-in state, region, playlist handling, and individual source availability can affect a job. Update the app, retry one accessible video, confirm account access, and then test the exact site again.

Can a 4K download use MP4, or does it require MKV?

Either container can carry 4K video, but the available choice depends on the source codec, audio tracks, and subtitles. Some combinations fit MKV more readily than the MP4 option a user expects, so choose by playback compatibility rather than resolution alone.

What is the official website for 4K Video Downloader Plus?

The official product home is 4kdownload.com. Use the product's own site to distinguish current 4K Downloads software, version information, plans, and supported platforms from unrelated download portals.

Why is a download stuck at 0% or retrieving information?

A practical 4K Video Downloader not working checklist starts with the app version, sign-in or access state, region, and source availability. Then compare a single video with a playlist; if one works, the failure may be tied to playlist parsing or a specific title.

Conclusion

The final choice should follow the scenario: use an active downloader for verified site support, a recorder when capture is acceptable, and an editor for files already on the device. Current compatibility beats the loudest 4K badge.
