MTS to WebP Converter

MTS to WebP Converter

MTS is the AVCHD clip your Sony or Panasonic camcorder writes to its memory card; WebP is a still-image format. There is no way for one to become the other frame-for-frame, so what this converter actually does is pull a frame out of the video and encode that single picture as WebP. Knowing which frame you get — and that you get a still rather than an animation — is most of what separates a useful result from a black rectangle.

How to Convert MTS to WebP

1. Upload Your MTS File: Drag and drop your .MTS clips onto the page or click "Add Files". This page accepts .mts only, and several clips can be queued with the same settings.
2. Set the Timestamp Under Frame Selection: "Specific Frame" is preselected with "Time (seconds)" at 0. Change it — on camcorder footage the very first frame is often a black lead-in or a shot still hunting for focus. A value a second or two into the action is almost always better.
3. Choose Quality Preset or Lossless: Quality Preset opens on "Very High (Recommended)" for a compact lossy WebP; switch "Lossless?" to "Yes" when you want the frame reproduced exactly. "Specific file size" and "Image resolution" are there if you need to cap either.
4. Convert and Download: Click Convert and save the WebP. No sign-up, no watermark.

What Comes Out: One Picture Per Frame

The pipeline decodes your clip, writes the requested frame out as a lossless PNG, then encodes that PNG to WebP — so the only lossy step added on top of the camcorder's own H.264 compression is the WebP encode itself, and switching "Lossless?" to "Yes" removes even that.

"Multiple Screenshots" changes the count, not the kind: setting a Capture Rate gives you a series of separate still WebP files sampled across the clip, one per extracted frame. It never produces a single animated WebP. If you want motion in one file, use MTS to GIF or MTS to APNG instead — both assemble frames into a real animation.

Frequently Asked Questions

Does this produce an animated WebP?

No. WebP as a format supports animation through its ANIM and ANMF chunks, but this converter's job here is frame extraction — you get a still image, and "Multiple Screenshots" gives you several still images rather than one animated file. For a moving result from the same clip, convert to GIF or APNG, or keep it as video with MTS to MP4.

Why is the frame I got black or out of focus?

Because "Time (seconds)" defaults to 0, which is the very first frame of the recording. Camcorders routinely start a clip while auto-exposure and autofocus are still settling, and some write a short dark lead-in, so frame zero is a poor sample of the shot. Scrub the clip in any player, note the moment you want, and type that number — decimals such as 2.5 work.

My 1440 × 1080 clip came out looking narrow — what happened?

AVCHD allows a 1440 × 1080 frame that is meant to be displayed as 16:9 using non-square pixels. Nothing in this pipeline applies pixel-aspect correction, so the stored 1440 × 1080 shape is what lands in the WebP and the image looks horizontally squeezed. The fix is explicit: under Image resolution choose "Width x Height" and enter 1920 × 1080, which restores the intended display shape.

Why does my still show comb lines across moving objects?

Your source is interlaced — most consumer AVCHD camcorders record 1080i, where each frame is built from two time-offset fields. There is no deinterlacing step anywhere in this conversion, so a single extracted frame keeps both fields and anything that moved between them shows as horizontal combing. Picking a moment with less motion helps; deinterlacing the clip in an editor before uploading fixes it properly.

Should I choose lossy or lossless WebP?

For anything web-bound, keep "Lossless?" on "No" and leave Quality Preset at "Very High" — Google measures lossy WebP at 25–34% smaller than a comparable JPEG at equivalent SSIM, which is the whole reason to use the format. Switch to "Yes" when the frame is going into further editing or print work and you want the pixels reproduced exactly; lossless WebP still comes in about 26% smaller than PNG.

What resolution will the WebP be?

Whatever the video's frame size is, unless you override it. Image resolution opens on "Keep original", so a 1920 × 1080 clip gives you a 1920 × 1080 still — roughly a 2-megapixel image. Note that "Preset Resolutions" sets the height and lets width follow the source aspect; if you need exact dimensions, use "Width x Height". Raising either number above the source only interpolates — the camcorder's sensor readout is the ceiling on real detail.

Will the WebP have a transparent background?

No, and not because of a setting. WebP supports full alpha, but the source is camera video and video frames are fully opaque — there is no transparency in an MTS clip to preserve. Any WebP produced from a camcorder frame will be a solid rectangular image.

Can I upload .m2ts files here?

Not on this page — the uploader accepts .mts only. The stream is the same recording either way (AVCHD writes .MTS on the card and the same footage is commonly relabelled .m2ts after import), so either use the matching M2TS page or rename the file extension before uploading.

What if the WebP won't open in an old program?

Support is broad in browsers — Chrome 32+, Firefox 65+, Safari 16+, Edge 18+ and Opera 19+, covering about 96% of tracked traffic — but some older desktop viewers and print workflows still do not read it. Extract the frame as JPG or PNG in that case; both go through the same frame-selection controls.

What happens to my camcorder footage after I convert?

The file is uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours later. Nothing is shared or made public, and there is no sign-up or watermark. The realistic constraint on a long AVCHD clip is upload size and time rather than the extraction itself, so if you only need a frame from late in a recording, consider trimming the source with the video cutter first.
