DDM 4.3.2

DDM 4.3.2

DDM is now free and open source (GPL-3.0). No trial, no licence keys, no ads. The whole program, the browser add-ons and the installer are in this repository.

Download: DDM-Setup-4.3.2.exe below. Runs on Windows 7, 8, 10 and 11 with nothing extra to install.

For the video fixes to take full effect, update the browser add-on to 4.0.8.

New in 4.3.2

• "Access denied" on sites that only answer a real browser: the add-on notes how your browser's own player asked for each video file and stream, and DDM asks the same way. This needs no rule per site.
• TikTok and other reels (Instagram, Facebook, X): after swiping to the next video, DDM gives you the one you are watching, not the one before.
• "Download this video" stays put: the button no longer jumps to another video or preview while you move the pointer to it.
• Real file names: the video's own name is used instead of the page's slogan, and no more files called "Video Player".

New in 4.3.1

• Dailymotion: opening another video no longer offers the first one again, and files are no longer all named "Dailymotion Video Player.mp4".
• Players inside other pages get the name of the page you are looking at.
• Adverts told apart: when a page loaded an advert's stream and the video's, DDM picks the video.
• Streams (HLS) start sooner.
• Upright videos are named by their short side: 1080 × 1920 is 1080p.

New in 4.3.0

• Free and open source: the 30-day trial and licence keys are gone. A DDM that was locked after its trial works again once updated.
• Videos from more sites: on sites DDM has no rule for, the add-on notes the stream the page's own player loads and DDM lists its qualities.
• Subtitles in every language a video offers: tick the ones you want, each saved as .srt.
• One tray icon for all downloads, with a live panel showing progress, speed and time left.
• Drag a finished file out of the Download complete window into a folder or another program.
• Smooth light/dark switch, and new versions pop up by themselves when DDM starts.
• After updating, the old installer and any older copy in another folder are removed. Your downloads, settings and portable copies are never touched.

Notes

• DRM-protected services (Netflix, Disney+ and similar) cannot be downloaded by any program.
• Found a site that doesn't work? Open an issue with the page address.
• Full list of changes: CHANGELOG.md

DDM 4.2.2

What's new in DDM

4.2.2 — November 2026

The download window

• Its title bar now has two minimize buttons, like IDM: the green arrow (Minimize to system tray) sits next to Minimize, Maximize and Close; the usual – still puts it on the taskbar
• The speedometer and the speed graph are gone; Show details / Hide details now shows or hides the parts of the file
• Everything else stays as it was: the rows, the progress bar, Speed limiter, When done, Security, the tray icon and its menu

4.2.1 — November 2026

The download window, like IDM's

• Download status now shows one row each: URL, Status, File size, Downloaded with its percentage, Transfer rate, Time left and Resume capability
• A big progress bar with the percentage on it: stripes slide while it downloads, amber when paused, red on an error (with what went wrong written under it)
• Show details / Hide details: the speedometer, the speed graph and the parts of the file are in the details; the window now really gets smaller when they're hidden, and on a small screen it opens with them hidden
• A second minimize button, like IDM: the green arrow at the top right (also in the title bar's menu) hides the window in the tray with its own icon; the title bar's – now puts it on the taskbar (Options → General can make it go to the tray again)

Unfinished downloads stay out of your folders

• .ddmpart files and a video's separate picture and sound now wait in DDM's own folder for unfinished downloads; your folders only ever get the finished file
• Options → Downloads → Folder for unfinished downloads lets you choose where they wait; what's already there moves along
• Downloads started with an older DDM finish where they already are

TikTok

• Reels that still said "No video was found" are found: the browser add-on (4.0.5) also catches the posts TikTok's own player loads as you scroll
• Photo slideshows offer their song, and DDM says when a post has no video

4.2.0 — November 2026

DDM in your language

• DDM now speaks বাংলা (Bengali), हिन्दी (Hindi), اردو (Urdu), العربية (Arabic), Español, Français, Português (Brasil) and Bahasa Indonesia, as well as English
• Options → General → Language changes every window, menu, button, message and notification at once; "Same as Windows" follows Windows' own language
• Bengali and Hindi use Windows' own fonts for them; Arabic and Urdu read from right to left
• File names, websites, video titles and your own categories always stay exactly as they are

Videos

• TikTok: reels that showed only "Open in DDM" now list every quality — your browser reads the post with your own session and hands it to DDM, so TikTok can't hide it any more
• Bilibili (bilibili.com, b23.tv links, multi-part videos, series episodes, bilibili.tv): every quality up to 4K, picture and sound downloaded with many connections each and joined into one MP4; with your browser's sign-in you get the qualities your account allows

Security

• Your browser's cookies for a site are sent only to that site, never to another site a download link redirects to
• A downloads list file someone sends you can no longer place files in Windows' startup folders or other system folders
• "Save page as PDF" locks the page copy down before anything in it can run
• X-Ray can't be made to use too much memory or read past a damaged archive's data
• Windows parts DDM loads by name always come from Windows' own folder
• The phone remote and the local player can't be held up by a slow or broken connection

4.1.1 — November 2026

TikTok

• Swiping through the feed: the button always downloads the video you're watching, even when the address bar still shows another one
• Every TikTok video is saved under its own caption (never "TikTok Embed.mp4" again), with its creator's name when it has no caption
• The download window shows the video's cover picture, like for YouTube
• When TikTok refuses DDM's first way of reading a video, its player page is read properly: caption, cover, length and the video itself
• Every quality TikTok has for a video is offered (1080p, 720p, 540p…)

Facebook, Instagram, Threads

• Reels and videos are saved under the caption the creator wrote, with the video's own cover in the download window

Windows

• "File already downloaded" and the browser add-on questions: the window is now as wide as its buttons, so no button is ever cut off
• "Add DDM to your browser": after clicking Add, the longer button no longer covers the browser's name

4.1.0 — November 2026

Videos

• TikTok: videos from the For You feed and from shared links (also links without the creator's name) are found again; DDM tries the video page and TikTok's own player page, with the cookies TikTok hands out
• When a site refuses to show its qualities, the button's Best quality downloads the very file your browser is playing, with your browser's sign-in — no more "No video was found"
• The button's menu says so when a site takes long to read, instead of waiting without a word
• Every video gets its own name: the caption shown next to it (TikTok feeds), its title, or its number — never "(20+) Facebook" or another tab title again, so downloads no longer ask to replace each other

Updates

• DDM's updates and site rules now come from github.com/officialdedsec/ddm (the old address is still read too)

4.0.9 — November 2026

Playlists, channels and subscriptions

• Download a whole YouTube playlist or channel at once (videos, Shorts or live): paste its address or use Tasks → Download playlist or channel…, untick what you don't want, choose the quality (up to MP3) and the folder
• Long playlists are read completely, not only their first page
• Subscribe to a playlist or channel and its new videos download by themselves, in the quality you chose (Tools → Subscriptions… to check now, pause or unsubscribe)

Phone remote

• Tools → Phone remote…: scan the QR code with your phone and see every download with its progress and speed; add links, pause, resume or remove downloads from the phone — nothing to install
• Works only inside your own network and only with the link's secret code; wrong tries are locked out; New link makes a new code at any time

Play while downloading

• Right-click a video or song → Play while downloading: DDM's player plays what has arrived, and when you jump ahead, that part of the file is fetched first
• Play in DDM for finished files, and Play in your browser for formats Windows can't play

4.0.8 — November 2026

Videos

• More sites by DDM's own engine: Snapchat, and every site that describes its videos in the page's data (JSON-LD, Next.js and app data), with all their qualities
• Adapts by itself when sites change: DDM's site rules (signed by DedSec) update by themselves every few hours, and at once when a video can't be found — no new version needed
• No outside programs at all any more: the spare torrent program (aria2) and the full FFmpeg download are gone; torrents use DDM's built-in engine only, and File tools use DDM's own built-in tools

DDM updates itself

• New versions are downloaded, checked (signed by DedSec) and installed by themselves as soon as nothing is downloading; DDM comes back the way it was, in the tray if it was there (Options → General → Update DDM by itself)

Your own categories

• View → Add category… (or right-click the categories): your own categories with their own file types and folder; rename, delete, change file types or folder with a right-click

Fixes

• The Undo card after removing downloads stays inside DDM's window: minimizing or closing the window to the tray ends it (the removal is final)

4.0.7 — November 2026

Videos from every site, with DDM's own engine

• DDM now reads videos from any site by itself — YouTube, Facebook, Instagram, Threads, TikTok, X, Vimeo, Dailymotion, Reddit and every other site with a video player (also players embedded from another site, and YouTube videos shown in other pages). Nothing is downloaded or installed for videos any more, ever
• Every quality of streamed videos (HLS .m3u8 and DASH .mpd): pieces are fetched many at a time on kept-open connections, key-protected streams (AES-128) are decrypted, separate sound tracks are joined, and one normal MP4 comes out without re-encoding. Live streams are recorded until you stop them
• The quality list appears in milliseconds once the page has arrived (even very large pages)
• Resume that doesn't give up: stream pieces are kept one by one, and when a site's video address expires DDM reads the page again by itself and carries on from the same byte or piece
• The old video component and its helper programs are gone; DDM removes what earlier versions fetched

Download windows

• Minimize a download window and it gets its own tray icon, like IDM: it fills up as the file arrives (green / amber when paused / red on an error) and its tip shows the name, percentage, KB/s and time left. Double-click it to bring the window back; right-click it to Show, Pause / Resume, Stop or Cancel
• Speeds in KB/s like IDM (for example 1,536 KB/s) in the download window, its Peak and per-connection speed, the list's Transfer rate, the status bar and the tray, with MB/s and Mbit/s underneath the big number
• X-Ray opens instantly from Download File Info: DDM reads the archive's contents as soon as the window shows it (the start and end of the file at the same time), and X-Ray says how long it took in milliseconds

Tools

• Remove image background (File tools → Pictures, or right-click a finished picture → File tools): the subject cut out on a transparent PNG by a small neural network built into DDM, with edges refined against the picture — on your PC, nothing uploaded, in a few seconds
• File tools make H.264 videos, AAC sound and GIFs with DDM's own built-in tools (Windows' own H.264 encoder): no extra download

Security and fixes

• Addresses from web pages, playlists and redire...
