Frequently Asked Questions

Can I convert horizontal 16:9 videos to vertical 9:16 without losing quality?

Yes. Pippit re-renders to 1080 × 1920 using smart scaling and reframing to preserve sharpness. You can choose fit, fill-with-blur, or background styles to keep subjects clear and text-safe areas intact.

Does Pippit auto-center faces and key subjects for TikTok?

It does. Auto Reframe detects faces and motion, re-centers important elements, and keeps titles or logos within safe zones so nothing essential gets cropped out.

What file formats can I upload?

Common video formats like MP4, MOV, MKV, and AVI are supported. You can also paste links to online videos. For audio, MP3 and WAV are supported when replacing or mixing tracks.

Can I add captions for TikTok after resizing?

Yes. Generate captions automatically or import SRT/ASS files. You can burn them into the video or export sidecar files, adjust fonts, colors, and placement for vertical layouts.

How fast is the 9:16 conversion?

Most short clips render in under a minute, depending on length and effects. Batch processing and cloud rendering help complete larger queues efficiently.
