Upload your 3GP video. PDF.to pulls frames out at the rate you pick and gives you a ZIP of GIF 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 GIF images have?
+
Source resolution. A 1080p 3GP produces 1920×1080 GIF stills; a 4K source produces 3840×2160 stills. Downscale in the options panel if needed.
我可以在特定的时间戳上提取一个框架吗?
+
Yes. Use the timestamp picker on the upload preview to scrub to the exact moment, then click 'extract this frame as GIF'.
框架抽取丢失了吗?
+
Each frame is decoded from the 3GP (lossless) and re-encoded as GIF. If GIF is lossless (PNG), no quality is lost. If GIF is JPG, we use high quality (90) by default.
Will the GIF stills be timestamped or numbered?
+
Yes — file names are zero-padded sequence numbers (GIF_00001.GIF, GIF_00002.GIF, ...) 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 GIF containing a grid of thumbnails, useful for storyboarding or video previews.
How large can my 3GP video be?
+
The free plan has a size limit that varies by file type; PRO allows much larger files. Frame extraction is fast even for long videos.
Is the 3GP to GIF extraction free?
+
Yes, within the free size limit. PRO unlocks larger files, higher extraction rates, and parallel processing.
Does PDF.to keep my 3GP or extracted GIF files?
+
No. Both the source 3GP and the GIF 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 GIF frames.
What if my 3GP has variable frame rate?
+
We normalize to a constant frame rate internally before extraction, so the GIF stills are spaced evenly in time regardless of how the source was encoded.
