3GP to JPEG Conversion FAQ
How do I extract images from a 3GP video as JPEG?
+
Upload your 3GP video. PDF.to pulls frames out at the rate you pick and gives you a ZIP of JPEG stills.
How many frames will I get from the 3GP?
+
By default, one frame per second of 3GP 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 JPEG images have?
+
Source resolution. A 1080p 3GP produces 1920×1080 JPEG 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 JPEG'.
Is the frame extraction lossy?
+
Each frame is decoded from the 3GP (lossless) and re-encoded as JPEG. If JPEG is lossless (PNG), no quality is lost. If JPEG is JPG, we use high quality (90) by default.
Will the JPEG stills be timestamped or numbered?
+
Yes — file names are zero-padded sequence numbers (JPEG_00001.JPEG, JPEG_00002.JPEG, ...) 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 3GP?
+
Yes — pick the 'contact sheet' option to get a single JPEG containing a grid of thumbnails, useful for storyboarding or video previews.
How large can my 3GP video be?
+
100 MB on the free plan, 5 GB on PRO. Frame extraction is fast even for long videos.
Is the 3GP to JPEG extraction free?
+
Yes for files under 100 MB. PRO unlocks larger files, higher extraction rates, and parallel processing.
Does PDF.to keep my 3GP or extracted JPEG files?
+
No. Both the source 3GP and the JPEG output ZIP are deleted within an hour. Conversion runs in an isolated worker.
Can I extract images only from a section of the 3GP?
+
Yes. Use the trim controls to set start and end times, and only the selected range produces JPEG frames.
What if my 3GP has variable frame rate?
+
We normalize to a constant frame rate internally before extraction, so the JPEG stills are spaced evenly in time regardless of how the source was encoded.
