Video and audio share the same problem on iPhone: the file iOS gives you is built for storage and editing, not for the app you’re trying to send it through. A 4K clip is too heavy for WhatsApp. A video needs to become a GIF for a chat that doesn’t support .MOV. A lecture recording is a video when all you want is the sound. Grabio’s video and audio tools all run Apple’s own on-device encoders, no upload, no watermark, no per-use cap.
Video
- Compress a video for WhatsApp — shrink a 4K clip to 720p before WhatsApp compresses it worse for you
- Trim a video without an app — cut dead seconds off the start or end using Apple’s own trim screen
- Convert a video to GIF — for iMessage stickers, Discord emojis, and Reddit comments that need a GIF, not a video file
Audio
- Extract audio from a video — pull the sound out as an M4A when all you want is the audio
- Convert an audio file to M4A — for car systems, ringtone tools, and apps that reject MP3 or WAV
- Convert audio to MP3, the one format Grabio hands off to a converter site since iOS has no on-device MP3 encoder
Download
- Download YouTube videos on iPhone, share the link and Grabio opens a clean downloader with the paste box ready
- Download TikTok, Instagram & other videos on iPhone, for TikTok, Instagram, and 13 other platforms, Grabio opens the download page with your link already loaded
If you’re downloading the original clip from TikTok, Instagram, or YouTube rather than converting something already on your phone, that’s a separate flow, share the link to Grabio and it opens a clean download page automatically. For file-size and format issues on the photo side, see photo tools; for PDFs, see PDF & document tools.
