Zumkor turns your photos, music and videos into the format you actually need. Drag in a file — or a whole folder. Pick what it should become. Click Convert. Nothing is uploaded. Zumkor itself isn't allowed online, so your files can't leave your Mac. Converting works with Wi-Fi off. No subscription. Buy once, keep it forever. WHAT DO YOU NEED TO DO? "My iPhone video won't play on their computer." iPhone .MOV files become an MP4 that plays anywhere — nothing for them to install first. "This video won't play either." MKV, WebM, AVI, WMV and FLV become an MP4 too. "It's too big to send." Pick Gmail, Outlook, iCloud Mail, WhatsApp, iMessage, Discord, Bluesky or Notion. Zumkor shrinks it to fit — and tells you if it can't. You never touch a bitrate. "They need my iPhone photos as JPGs." HEIC to JPG — hundreds at once, still looking like the originals. "These photos are too big." Make them smaller for email, a website or a chat. You pick the size in words, not pixels. "I just want the sound." Pull the audio out of a video, or make a plain, normal MP3. "I only need part of this video." Trim it to the good bit first. No video editor needed. "I'm putting this on YouTube." A ready-to-upload 1080p or 4K video, with the sound set to YouTube's own level so it isn't too quiet. "I recorded my screen." Turn it into a GIF for Slack, GitHub or a bug report — even one small enough that Discord plays it on its own. "I need the subtitles as a separate file." Pull them out as SRT or VTT — or turn an SRT you already have into a VTT. "There are no subtitles and I need some." Zumkor listens to your video and writes them for you, right on your Mac. (Needs macOS 26 or later. The first time, your Mac downloads Apple's speech files.) "I found old camcorder tapes and DVDs on a hard drive." AVCHD camcorder files (.MTS, .M2TS) and DVD files (.VOB) become MP4s you can finally watch and share. (Shrinking, audio, GIF and subtitles aren't offered for this older footage.) "I'm publishing an episode." One video in, two files out: a 1080p YouTube video and a podcast audio file, each at the right loudness, each in its own folder. "I'm sending photos to someone." Remove the personal bits first — where the photo was taken, and what took it. One click. "I'm delivering files to a client." Name them the way the client wants: the date, their name, numbering. Names come out safe on Windows too. "My old music won't open." WMA and OGG files become MP3, M4A or FLAC. "I shoot RAW." Canon, Sony, Nikon, Fuji, Olympus, Panasonic, Pentax, Sigma, Hasselblad and DNG to JPG or TIFF, in one batch. "They're still in Photos." Bring photos and videos in straight from your library. No exporting first. WHY PEOPLE LIKE IT • Your files never leave your Mac. Zumkor itself isn't allowed online. • No subscription.
