Yes, within the free size limit. PRO supports much larger FLV files and parallel batch extraction.
PDF.to 读取或存储我的FLV 内容吗?
+
No. The FLV video and the FLAC audio output are deleted within an hour. Conversion runs in an isolated worker.
我能从多个 FLV 文件中提取音频吗?
+
Yes — drop a folder of FLV videos and you will get a ZIP of FLAC files back, one per source video.
FLAC 将保存标签和元数据吗?
+
Title, artist, and album tags are populated from the FLV container metadata when available. You can edit them after extraction with our audio-tag tool.
转换器是否对流视频 URL 工作?
+
No — PDF.to converts files you upload, not third-party stream URLs. Download the FLV legally first, then upload it for FLAC extraction.
Why is the FLAC file much smaller than the FLV video?
+
Because the video stream (typically 90%+ of file size) is discarded. Only the audio track ends up in the FLAC, which is why it can drop from gigabytes to a few megabytes.
