3GP to JPG Conversion FAQ

How do I extract frames from a 3GP video as JPG images?
+
Upload the 3GP and the converter exposes a frame-extraction picker: every Nth frame, frames at specific timestamps, or one frame per second. Each chosen frame is encoded as an individual JPG file and the full set is bundled into a ZIP archive for download. 3GP is the container the 3GPP standardised for early mobile phones, when video had to fit a 176x144 screen and a 2G data plan. JPG is the JPEG standard from 1992, served under the .jpg, .jpeg and .jfif extensions alike, and after three decades it is still the format most cameras and most websites use for photographs.
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 JPG 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.
Quality 85 is the sensible default and the one used unless you change it — visually indistinguishable from the source at normal viewing distance, at roughly a fifth of the size of a lossless equivalent. Push to 95 for anything that will be edited or printed, and drop to 70 for thumbnails where size dominates. JPG is lossy: the image is transformed with a DCT, quantised, and entropy-coded, with a quality knob controlling how much is discarded.
The same resolution as the 3GP video — a 1080p 3GP produces 1920×1080 JPG frames; a 4K 3GP produces 3840×2160 JPG frames. Use the resize utility after extraction if you want smaller thumbnails or social-media-sized crops.
Yes, but be careful with file count — a 30fps 1-minute 3GP produces 1,800 JPG frames. We pack them into a ZIP automatically. For longer clips, the "1 per second" option (60 frames) or specific timestamps gives a manageable result.
Yes — colour is decoded with the matrix the source 3GP uses (BT.709 for HD, BT.2020 for 4K HDR). HDR sources are tone-mapped to SDR on extraction to JPG because most JPG formats (PNG, JPG) cannot store HDR pixel ranges natively.
Depends on resolution and JPG codec. A 1080p PNG frame is typically 2 to 5 MB; a 1080p JPG at quality-85 is 200 to 500 KB; a 4K PNG is 6 to 15 MB. At the extreme, every-frame PNG extraction of a 10-minute 1080p 3GP produces ~50 GB total.
The 3GP container does not store per-frame EXIF the way a still camera does, so the JPG files come out with empty EXIF. We embed a `creation_time` field pointing at the source frame timestamp so you can re-sort the bundle by capture order.
Frame extraction is fast — typically 20 to 30% of source duration on the standard pipeline. A 5-minute 3GP → JPG bundle finishes in about a minute regardless of frame count, because the bottleneck is the JPG encoder, not the 3GP demuxer.
Yes — the advanced option accepts a comma-separated list of timestamps (e.g. `00:01:23,00:05:00,00:10:42`) and produces one JPG file per timestamp. Useful for chapter thumbnails, scene reference shots, or thumbnailing long lectures.
Yes — same privacy model as every conversion. Source video and extracted JPG frames are processed in isolated workers and deleted within minutes; no human review, no training corpus, no third-party access.
Almost always motion blur baked into the 3GP source — the camera or subject was moving when the frame was captured. Pick timestamps from static scenes, or extract adjacent frames and choose the sharpest. The pipeline does not synthesize detail that was not there.

3GP

3GP is a multimedia container format developed for 3G mobile phones. It can store audio and video data and is commonly used for mobile video playback.

JPG

JPG files use lossy compression optimized for photographs, giving small file sizes while retaining visual resolution.
