3GP to PNG Conversion FAQ
How do I extract individual frames from 3GP as PNG images?
+
Upload the 3GP and open the options. Frame Extraction has two modes: Single Frame saves one PNG from the second you enter (for example 1, 5 or 10.5), and All Frames saves every frame of the video as a PNG image. There is no every-Nth-frame or one-per-second mode. 3GP is the container the 3GPP standardised for early mobile phones, when video had to fit a 176x144 screen and a 2G data plan. PNG was designed in 1996 as a patent-free replacement for GIF, and became the web’s default lossless image format.
Can I get the PNG frames without the subtitles?
+
Only if the 3GP never had them burned in, because 3GP has no selectable subtitle stream to switch off. Anything a 3GP shows on screen is in the picture itself, so it is in every PNG the extraction produces and no setting removes it afterwards. Where a separate subtitle file exists alongside the video, extract from a source that kept the two apart and the frames come out clean. 3GP is capped at low resolutions and mono speech-grade audio; upscaling it will not restore detail that was never captured.
Does the PNG output support transparency?
+
The format does, but the source has no alpha to give it — video frames and rendered pages are fully opaque by nature, so every pixel arrives solid. The alpha channel is still useful afterwards: it means you can cut a subject out of the PNG later without changing format again. PNG is the right choice for screenshots, logos, line art and anything with hard edges or transparency — no ringing, no colour banding.
How big will the PNG files be?
+
Larger than you might expect, because PNG keeps every pixel exactly rather than approximating. A 1080p still lands around 2-5 MB and a 4K still around 6-15 MB, so a long extraction run adds up quickly. That is the right trade when the images feed further processing, and the wrong one when they are going straight onto a web page. PNG uses DEFLATE compression over filtered scanlines, so every pixel survives exactly, plus a full 8-bit alpha channel.
At what resolution do the extracted PNG images come out?
+
Same resolution as the source 3GP: a 1080p 3GP produces 1920x1080 PNG frames, a 4K 3GP produces 3840x2160 PNG frames. The converter does not upscale or downsample — pixel dimensions are pulled straight from the decoded frame. Use /resize-image/ after extraction if you need smaller thumbnails.
Can I extract every frame of a 3GP as PNG?
+
Yes, with All Frames in the Frame Extraction option, but watch the count: one minute of 30 fps video gives 1,800 PNG images. For a single still, choose Single Frame and enter the second you want instead.
Will the PNG frames preserve the 3GP colour grading?
+
HDR footage is not tone-mapped: each frame is converted from the 3GP as it is decoded, so a frame from an HDR 3GP can look flat or washed out as a PNG. Standard (SDR) video keeps its colours.
How long does frame extraction from 3GP to PNG take?
+
It depends on the size and length of the file. Small documents and images are usually ready quickly. Long videos take the longest, because most video conversions re-encode every frame.
Is my 3GP private during frame extraction?
+
Yes. Uploaded 3GP files are processed on our own conversion servers, no person reviews them, and they are never shared. The upload and the converted PNG are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
