Which 4K Download App Should I Use for YouTube, TikTok, or Instagram?

Pick by the site you are downloading from: 4K Video Downloader Plus for YouTube and other general video sites, 4K Tokkit for TikTok videos and accounts, 4K Stogram for Instagram photos, Stories and Reels, and 4K YouTube to MP3 when you only want audio from YouTube. 4K Download also offers 4K Video to MP3 (extract audio from any video), 4K Image Compressor (shrink JPG, PNG, WEBP, HEIC files), 4K Slideshow Maker, and an Android app for 4K Video Downloader Plus. The main functionality of these applications is free and, per the site, will stay free — no watermarks, no registration, no payments — with premium features for advanced use.

Quick match: content type → app

If your source is YouTube (or a general video site)

Use 4K Video Downloader Plus. The site describes it as a free video downloader for YouTube and other sites, and it is the only product in the lineup with a dedicated Android app ("4K Video Downloader for Android — download video and audio on Android devices").

Choose 4K YouTube to MP3 instead when you specifically want YouTube turned into MP3 files — the site positions it as "turn YouTube videos into MP3 files, fast and easy." If the audio you want lives inside a video file you already have rather than a YouTube link, 4K Video to MP3 is the matching tool ("extract audio from video").

If your source is TikTok

Use 4K Tokkit. Its stated job is downloading TikTok videos from accounts and hashtags — useful when you want a creator's back catalog rather than one clip at a time.

If your source is Instagram

Use 4K Stogram. It handles Instagram photos, Stories, Reels and hashtags, so it covers both single posts and ongoing collection from an account or tag.

Two things to check before installing

• Platform: the site lists Windows, macOS and Ubuntu for the desktop lineup, plus the separate Android app for 4K Video Downloader Plus. Confirm your OS is covered before downloading.
• Free vs. premium: core functionality is free with no registration or watermarks; premium features exist for advanced use. The site also maintains a subscription cancellation page, so paid plans exist — check current terms on the Store page if you need premium features, since pricing is not stated in the material here.

Common mix-ups

• 4K Video Downloader Plus vs. 4K YouTube to MP3: both handle YouTube, but one saves video/audio files and the other is built around MP3 output. If you want the video, the MP3 tool is the wrong pick.
• 4K Tokkit vs. 4K Stogram: they look similar but are split by platform — TikTok vs. Instagram. There is no single app in this lineup that covers both.
• 4K Video to MP3 vs. 4K YouTube to MP3: one works on video files, the other on YouTube links.
