Need help?Convert M4V to WebP Online
Grab a single frame from an Apple M4V video and save it as a WebP still image — the format Google built to be smaller than JPG or PNG at the same visual quality. Pick the exact timestamp you want (down to the millisecond), and the converter pulls that frame out and encodes it as WebP. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared or made public.
How to Convert M4V to WebP
- Upload Your M4V File: Drag and drop your
.m4vfile onto the page or click "Add Files". You can queue several clips and convert them with the same settings. - Set the Frame Time: Under Advanced Options, choose "Specific Frame" and enter a value in "Time (seconds)" — for example
2.100captures the frame at 2 seconds and 100 milliseconds. Use "Multiple Screenshots" if you want several stills across the clip instead of one. - Pick Quality and Resolution: Leave "Quality Preset" on "Very High (Recommended)", or switch on the "Lossless?" toggle for a pixel-perfect frame. Keep the original resolution or scale it down with a Preset Resolution.
- Convert and Download: Click "Convert" and save your WebP image. No sign-up, no watermark.

Frequently Asked Questions
Why won't my iTunes M4V file convert?
Most M4V files purchased or rented from the iTunes Store and Apple TV are locked with Apple's FairPlay DRM, and that encryption blocks any frame from being read or extracted — the same reason VLC and HandBrake refuse those files. M4V you exported yourself, recorded, or downloaded DRM-free converts normally. There is no legal way to strip FairPlay here; if the source is protected, the conversion will fail.
Does this create an animated WebP or a still image?
A still image. This tool extracts the single frame at the timestamp you choose (or a handful of frames with "Multiple Screenshots") and saves each as its own WebP. If you want a short looping animation instead, convert the clip with our M4V to GIF tool, which produces an animated result.
Will the WebP look as sharp as the original frame?
At the default "Very High" preset the difference is hard to spot, and Google's own measurements put WebP roughly 25-34% smaller than an equivalent-quality JPG. For an exact copy of the frame — useful for editing or print — turn on the "Lossless?" toggle; the file will be larger but every pixel matches the source.
Which browsers can display the WebP I get?
Static WebP renders in Chrome 32+, Firefox 65+, Edge 18+, and Safari 16+ (basic WebP arrived in Safari 14 on macOS Big Sur). If you need a frame that opens everywhere, including older browsers and legacy apps, extract it as a M4V to JPG still instead.
How large can the M4V I upload be?
In our testing a 1080p M4V uploads and returns a frame in a few seconds; there is no fixed in-app cap, so the practical limit is your upload size and connection speed rather than any per-file ceiling. A short clip is all that is needed anyway — only the frame at your chosen timestamp is decoded, not the whole video.
