Troubleshooting & FAQ
Q: Why did my video open in a new tab instead of downloading directly?
Some mobile browsers (like iOS Safari or Chrome on Android) attempt to stream media in a native player rather than triggering an instant file save. If this happens, simply tap the browser's Share icon and tap "Save to Files" or "Download video".
Q: Does SVK Downloader store copies of my downloaded videos?
No. SVK Downloader operates on a serverless stream architecture deployed to Cloudflare Edge. Media is streamed directly from source pipelines to your browser buffer with zero permanent server-side logging.
Q: How do I play 320kbps MP3 audio on iPhone?
Once downloaded, tap the file in your Safari downloads manager. You can play it immediately with the native iOS Audio Player, or share it into Apple Music / GarageBand / VLC for offline listening.
