APNG to MTS Converter

APNG (Animated PNG) is a lossless, frame-based image format with full transparency; MTS is the file extension AVCHD camcorders write to memory cards — H.264 video inside an MPEG-2 transport stream. Turning an animation into MTS is a narrow job: it only makes sense if you are feeding a clip into a camcorder-style editing or AVCHD authoring workflow that expects the .mts extension. If you just want a playable, shareable, editable video, convert your APNG to MP4 instead — MP4 is roughly three times smaller, plays on phones and the web, and is accepted by YouTube, Instagram, and TikTok, none of which accept .mts uploads. Because transport-stream video has no alpha channel, this converter flattens any transparency onto a solid Background Color you pick.

How to Convert APNG to MTS

1. Upload Your APNG File: Drag and drop your animated PNG onto the page or click "Upload." You can queue several files at once.
2. Pick a Merge Strategy: Choose "Merge images" to combine multiple uploads into one MTS stream, or "Video per image" to output a separate file for each.
3. Set Image Duration, Background Color, and Quality Preset: Image Duration sets how long each frame is held; Background Color fills the area where the APNG was transparent (default Black); the Quality Preset defaults to "Very High." Use the Video resolution control to keep the original size or pick an HD preset.
4. Convert and Download: Click Convert and download your MTS. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark.

Frequently Asked Questions

What is the difference between an MTS and an M2TS file?

They hold the same thing — H.264 video in an MPEG-2 transport stream — and differ only by where they come from. A camcorder writes .mts files to its memory card; once you import that footage to a computer or onto a Blu-ray, the same stream is usually labeled .m2ts. This tool outputs the camcorder-side .mts extension. If your software specifically wants .m2ts, use our APNG to M2TS converter instead.

Should I really convert my APNG to MTS, or is MP4 the better choice?

For nearly everyone, MP4 is better. MTS exists for AVCHD camcorder and disc-authoring chains; outside that, it is a liability — files are larger, and social platforms and most phones reject the .mts extension. Both MTS and MP4 carry H.264 video, so you lose nothing in codec terms by choosing MP4. Pick MTS only when an AVCHD-only editor or authoring tool demands that exact extension. Otherwise convert APNG to MP4.

What happens to my APNG's transparency in the MTS file?

It is flattened. H.264 video has no alpha channel, so every transparent pixel is replaced by the Background Color you choose (Black by default). Match that color to wherever the clip will be composited so the edges stay clean. If keeping transparency matters, MTS — and any standard video container — is the wrong target; leave the file as APNG.

Will the MTS file have sound, and will the animation loop?

No on both counts. APNG is a silent image format, so the resulting MTS has no audio (the tool still writes an AC-3 audio configuration because AVCHD players expect one, but there is nothing to encode). And MTS has no per-clip loop flag the way APNG does, so the animation plays through once across the duration you set rather than repeating.

How does Image Duration change the length of my MTS clip?

Image Duration is how long each frame of your APNG is shown in the output. In our testing, a 12-frame APNG at the "1/24s (single frame at 24fps)" setting produced a roughly half-second clip, while "1 second per frame" stretched those same 12 frames into a 12-second video. Pick a short per-frame duration to keep the animation playing at its original speed instead of as a slideshow.

What resolution should I pick so the MTS file stays AVCHD-compatible?

AVCHD is defined around HD frame sizes — 720p, 1080i, and 1080p — so leave the Video resolution on an HD preset such as 1920×1080 for the broadest compatibility with camcorder editors. A non-standard size may still play in VLC but can be rejected by stricter AVCHD-only software.

What software opens an MTS file once I download it?

VLC, MPC-HC, PotPlayer, Adobe Premiere Pro, Sony Vegas, and CyberLink PowerDirector all read .mts, as do many Blu-ray players and PlayStation consoles. On a plain desktop without those tools, an .mts file often will not open in the default photo or video viewer — another reason most people are better served by MP4.

Are my uploaded files kept private?

Yes. Files are uploaded over an encrypted (TLS) connection, processed on our servers, and deleted automatically after a few hours. There is no sign-up, no watermark, and your files are never shared or made public.
