TS to MP4 Converter
Convert TS and MPEG-TS files to MP4, merge HLS video segments, and process supported AES-128 encrypted streams locally in your browser.

Files are processed on this device and are not uploaded to FlowPick.
Fast local conversion
Convert MPEG-TS without unnecessary quality loss
FlowPick reads the transport stream and repackages compatible video and audio tracks into MP4 instead of encoding them again.
Direct TS to MP4 remuxing
Compatible H.264, AAC, and MP3 streams are copied into MP4 without changing their visual or audio quality.
Merge ordered HLS segments
Select multiple TS files or use a local M3U8 playlist to preserve playlist order and timing.
AES-128 HLS support
Use playlist keys, explicit IV values, sequence-derived IVs, and supported key rotation for authorized encrypted media.
When to convert TS video to MP4
A more widely supported MP4 container makes transport-stream recordings easier to play, organize, share, and edit.
Camera and recorder exports
Convert TS, MTS, or M2TS recordings into an MP4 file that is easier to open on phones and computers.
HLS segments saved locally
Combine ordered TS fragments from a permitted HLS workflow into one playable MP4 file.
DVR and broadcast recordings
Repackage compatible transport-stream captures for players and editing applications that prefer MP4.
Authorized encrypted archives
Decrypt standard AES-128 HLS segments with a key you are permitted to use, then save the result as MP4.
Quick guide
How to convert TS to MP4
Select the input that matches your files. The converter inspects, decrypts when configured, and repackages compatible streams locally.
Choose the TS source
Add one TS file, several ordered segments, or an M3U8 file together with every referenced local segment.
Review encryption details
For AES-128 HLS, add the referenced key when necessary and verify any IV or starting media sequence override.
Convert and download
Start the local conversion, keep the tab open during finalization, and download the completed MP4.
Codec and encryption compatibility
The current converter directly supports MPEG-TS containing H.264 video with AAC or MP3 audio. Other codecs may require re-encoding and are not converted by this first version.
Only standard HLS AES-128 identity encryption is supported. SAMPLE-AES and DRM systems such as Widevine, FairPlay, and PlayReady are not supported. Use the tool only for media you own or are authorized to process.

TS to MP4 questions
Does TS to MP4 conversion reduce video quality?
Not for compatible streams. The video and audio tracks are repackaged into an MP4 container without being encoded again.
Can I merge several TS files into one MP4?
Yes. Select the files together and FlowPick sorts numbered filenames naturally. For exact playlist order and timing, include the local M3U8 file.
How does AES-128 HLS decryption work?
The converter reads the key declaration from the M3U8 playlist, uses its explicit IV or derives one from each media-sequence number, decrypts each segment, and validates the MPEG-TS packets before conversion.
Can this tool remove DRM?
No. It does not support SAMPLE-AES, Widevine, FairPlay, PlayReady, paywall bypassing, or other DRM systems.
Are my files or encryption keys uploaded?
No. Selected files and key values are processed locally in your browser and are not uploaded to a FlowPick conversion server.
Why was no MP4 produced?
The file may be damaged, ordered incorrectly, encrypted with a different key or IV, or contain a codec this version cannot remux into MP4.
