We re-package or re-encode your 3GP into the WebM 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 3GP to WebM lossy?
+
If the codec inside 3GP is compatible with WebM, 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.
What resolution will my WebM output have?
+
Privzeta ločljivost izvora. Opcijske plošče omogočajo, da se zmanjšajo na 1080p, 720p, 480p, ali izberejo po meri velikost – koristno za skrajševanje datotek za izmenjavo ali pošiljanje.
Ali pretvornik ohranja zvočne sledi in podnapise?
+
Yes when WebM 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 3GP file be?
+
Free accounts have a size limit that varies by file type; PRO accounts allow much larger files. For very large 3GP files we recommend the PRO plan or pre-trimming with our video-trim tool.
What codec is used inside the WebM output?
+
We pick the best-supported codec for the WebM container — H.264 for MP4 / MOV / FLV, VP9 for WebM, AV1 when targeting modern web, H.265 when WebM supports it. You can override in the options panel.
Lahko pretvornik spremeni hitrost okvirja?
+
Da. Opcijske plošče razkrivajo ciljne hitrosti okvirja (24, 25, 30, 60). Privzeto ohranimo hitrost vira okvirja.
Will my converted WebM play on TV, phone, and browser?
+
Yes. Our default profile targets universal playback — H.264 + AAC inside WebM works on every major platform, browser, and smart TV from the last decade.
Is the 3GP to WebM 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 3GP files?
+
Yes. 4K is preserved by default; downscale via the options panel if needed. HDR is preserved when WebM supports it (MKV, MP4 with HEVC) or tonemapped to SDR when targeting older formats.
How long does a 3GP to WebM conversion take?
+
Stream-copy (kompatibilna kodek) konča blizu hitrosti diska – 1 GB datoteka v veliko manj kot minuto. Prerazporeditev lestvice z ločljivostjo in dolžino; pričakovati približno v realnem času za 1080p na prostem načrtu, hitreje na PRO.
Do you keep my 3GP video?
+
No. The 3GP upload and WebM output are deleted within an hour. Conversion happens in an isolated worker with no content logging.
