We re-package or re-encode your MPEG into the 3GP container. When the codec matches, we copy streams (fast, lossless); when it does not, we re-encode with H.264 / H.265 / VP9 at a high default quality.
Is converting MPEG to 3GP lossy?
+
If the codec inside MPEG is compatible with 3GP, the conversion is a remux (no quality loss). If we need to re-encode, the default CRF setting is visually lossless for typical viewing distances.
Yes when 3GP supports them (MP4, MKV, MOV). All audio tracks, languages, and embedded subtitles are kept. For single-track containers (3GP, FLV), only the default track survives.
How big can my MPEG file be?
+
Free accounts have a size limit that varies by file type; PRO accounts allow much larger files. For very large MPEG files we recommend the PRO plan or pre-trimming with our video-trim tool.
What codec is used inside the 3GP output?
+
We pick the best-supported codec for the 3GP container — H.264 for MP4 / MOV / FLV, VP9 for WebM, AV1 when targeting modern web, H.265 when 3GP supports it. You can override in the options panel.
Will my converted 3GP play on TV, phone, and browser?
+
Yes. Our default profile targets universal playback — H.264 + AAC inside 3GP works on every major platform, browser, and smart TV from the last decade.
Is the MPEG to 3GP converter free?
+
Yes, within the free size limit. PRO unlocks larger files, GPU-accelerated transcoding, and 4K output.
Does PDF.to support 4K and HDR MPEG files?
+
Yes. 4K is preserved by default; downscale via the options panel if needed. HDR is preserved when 3GP supports it (MKV, MP4 with HEVC) or tonemapped to SDR when targeting older formats.
How long does a MPEG to 3GP conversion take?
+
د جریان کاپي (متوافق کوډ) د ډیسک سرعت ته نږدې پای ته رسیږي - د 1 GB فایل په ښه توګه د دقیقې لاندې. د حل او اوږدوالي سره د بیا رمز کولو پیمانه؛ د وړیا پلان لپاره د 1080p لپاره په سمه توګه ریښتیني وخت تمه وکړئ، په PRO کې ګړندی.
Do you keep my MPEG video?
+
No. The MPEG upload and 3GP output are deleted within an hour. Conversion happens in an isolated worker with no content logging.
