M4V to PNG Conversion FAQ
How do I extract images from a M4V video as PNG?
+
Upload your M4V video. PDF.to pulls frames out at the rate you pick and gives you a ZIP of PNG stills.
How many frames will I get from the M4V?
+
By default, one frame per second of M4V runtime. The options panel lets you pick every frame, one per 5 seconds, only key-frames, or a custom interval.
What resolution will the extracted PNG images have?
+
Source resolution. A 1080p M4V produces 1920×1080 PNG stills; a 4K source produces 3840×2160 stills. Downscale in the options panel if needed.
Can I extract a single frame at a specific timestamp?
+
Yes. Use the timestamp picker on the upload preview to scrub to the exact moment, then click 'extract this frame as PNG'.
Is the frame extraction lossy?
+
Each frame is decoded from the M4V (lossless) and re-encoded as PNG. If PNG is lossless (PNG), no quality is lost. If PNG is JPG, we use high quality (90) by default.
Will the PNG stills be timestamped or numbered?
+
Yes — file names are zero-padded sequence numbers (PNG_00001.PNG, PNG_00002.PNG, ...) so they sort correctly. The options panel can also embed the source timecode in EXIF.
Can I make a contact-sheet or thumbnail grid from the M4V?
+
Yes — pick the 'contact sheet' option to get a single PNG containing a grid of thumbnails, useful for storyboarding or video previews.
How large can my M4V video be?
+
100 MB on the free plan, 5 GB on PRO. Frame extraction is fast even for long videos.
Is the M4V to PNG extraction free?
+
Yes for files under 100 MB. PRO unlocks larger files, higher extraction rates, and parallel processing.
Does PDF.to keep my M4V or extracted PNG files?
+
No. Both the source M4V and the PNG output ZIP are deleted within an hour. Conversion runs in an isolated worker.
Can I extract images only from a section of the M4V?
+
Yes. Use the trim controls to set start and end times, and only the selected range produces PNG frames.
What if my M4V has variable frame rate?
+
We normalize to a constant frame rate internally before extraction, so the PNG stills are spaced evenly in time regardless of how the source was encoded.
