Preguntas frecuentes: Obter desde B4K (vídeos, imaxes, son)

Paste any public B4K URL into the box at the top of this page and press the preserve button. Soundc reads the B4K link, fetches the source media, and streams the MP4 file back to your browser without storing it on our servers.

Yes — free users get a generous daily allowance for B4K downloads. Paid plans remove the cap if you batch many B4K URLs in a session.

B4K hosts a mix of video, photo, and audio. Soundc matches whatever the source post delivered — usually MP4, JPG — at up to 1080p.

No. B4K exposes its content publicly without a sign-in wall, so Soundc can preserve any public URL you paste — no B4K account required, no Soundc account either.

B4K delivers fairly standard content endpoints, so Soundc preserves what B4K streams without extra workarounds. The main limits are public visibility and the originating uploader's quality settings.

B4K serves a wide audience and so does Soundc — creators archiving their own work, fans saving favorites before they get pulled, and researchers building reference collections all paste B4K URLs into Soundc daily.

Soundc preserves one B4K URL per submission. For a channel or playlist, paste each video URL individually — B4K's grouping pages are navigation shells, not single-file endpoints.

B4K on mobile and Soundc on mobile are a natural pair. Open Soundc in your phone's browser, paste a B4K URL from the share menu, and the file lands directly in your device's downloads folder.

Soundc routes B4K mp3 requests through the extraction path tuned for that file type. The general B4K tutorial works too, but the mp3-specific page surfaces the right options up front.

Neither. Soundc reads B4K's public delivery endpoints exactly the way a normal browser does — no API key, no charged request, no notification back to B4K or to the original uploader.

B4K occasionally changes how its delivery endpoints are structured. When that happens, Soundc patches the extractor usually within a day or two — recheck shortly, or paste a different B4K URL to confirm it isn't a one-off post.

Directly in your browser's default downloads folder. Soundc doesn't keep a copy on our side — once the B4K file lands on your device, it's yours alone.
