How to Convert MTS to MPEG — Quick & Free
Fast, instant MTS to MPEG conversion. No signup required. Just drop your .mts file and get .mpeg in seconds.
Batch Settings
Generation loss — quality may degrade
MTS uses lossy compression, and so does MPEG. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Some metadata may not survive
Your MTS file may contain AVCHD metadata metadata. MPEG has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
What compression artifacts to expect
MPEG lossy compression can produce blockiness, noise (early codec). At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.
About MTS to MPEG Conversion
Short answer: yes, you can convert MTS to MPEG online for free, and some quality differences may occur depending on the format types. Just upload your .mts file to CocoConvert, pick MPEG as the output, and click Convert. The whole process takes seconds.
Now for the details. MTS (AVCHD) is the format from camcorders recording in high-definition AVCHD. MPEG is an early standard for video compression — the foundation for modern codecs like H.264. Converting between these two formats lets you improve file compatibility across devices.
Full Name: MTS uses AVCHD Video, while MPEG uses MPEG Video. Compression: MTS uses Lossy, while MPEG uses Lossy. Color Depth: MTS uses 8-bit, while MPEG uses 8-bit.
Your MTS file is decoded and re-encoded as MPEG. MTS uses lossy compression, and so does MPEG. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Common misconception: ""I'll convert to MPEG and then back to MTS — it'll be the same"" — in reality, each lossy conversion cycle permanently degrades quality. going mts → mpeg → mts will produce a noticeably worse file than the original. always keep your source file.
CocoConvert runs entirely online — no software to install, no account to create. Your files are encrypted during upload (TLS), processed on isolated servers in Germany, and permanently deleted after 24 hours. It works in Chrome, Safari, Firefox, Edge, and all mobile browsers.
Need to convert more than one file? Free users can do 5 per hour. Pro gets 100 per hour with files up to 5 GB each.

What Happens When You Convert MTS to MPEG
Your MTS video is transcoded — video and audio streams are decoded and re-encoded into the MPEG container. This is a lossy process that takes time proportional to the video duration.
Your MTS file is demuxed — video, audio, and subtitle streams are separated
The video stream is decoded frame-by-frame, then re-encoded with MPEG-compatible codecs (typically H.264 for MP4)
The audio stream is decoded and re-encoded (or copied if the codec is compatible)
Subtitle and chapter data is preserved where the target supports it
Streams are muxed into the MPEG container and the file is saved

Should You Convert MTS to MPEG?
When to Convert
- ✓Your MTS file won't open on a recipient's device or in an application
- ✓A website, service, or platform only accepts MPEG uploads
- ✓You need maximum device and software compatibility
When NOT to Convert
- ✗You're converting just because the file "seems old" — re-encoding lossy-to-lossy always degrades quality
Common Mistakes When Converting MTS to MPEG
"I'll convert to MPEG and then back to MTS — it'll be the same"
Each lossy conversion cycle permanently degrades quality. Going MTS → MPEG → MTS will produce a noticeably worse file than the original. Always keep your source file.
Frequently Asked Questions
Is MTS to MPEG conversion free?
Yes. CocoConvert offers free MTS to MPEG conversion with generous daily limits — 25 minutes of processing time and up to 5 files per hour (250 MB each). Pro plans remove these limits.
How fast is MTS to MPEG conversion?
Most files convert in 2–10 seconds depending on size. Large video files may take 30 seconds. Batch jobs process in parallel for maximum speed.
What happens to my files after conversion?
Your uploaded MTS file and the converted MPEG file are both automatically deleted from our servers within 24 hours. They are never shared, sold, or analysed.
Does converting MTS to MPEG lose quality?
MTS uses lossy compression, and so does MPEG. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Can I convert MPEG back to MTS?
Yes, CocoConvert supports MPEG to MTS conversion as well. However, if the original conversion involved lossy compression, converting back won't recover the lost data.
