Video Toolbox: Trim & Compress

Nine handy video tools in one small app. Pick a video, adjust, export. Everything runs on your phone: no uploads, no sign-in, no watermark.

TRIM
• Drag the handles or play and tap "Start here" / "End here"
• Trimming keeps the original quality and is fast

COMPRESS
• Compress to a size: pick 8, 16, 25, 50 or 100 MB (or type your own) to fit chat apps, email and upload forms. The app chooses the resolution and bitrate, and compresses again if the first try is too big
• Or pick High (1080p), Medium (720p) or Small (480p)
• See the estimated size before you export
• If your phone's encoder can't handle a video's size, it drops to a lower resolution instead of failing
• Saved as H.264 MP4, which plays almost everywhere

VIDEO TO GIF
• Choose any part up to 20 seconds
• 240, 320 or 480 px wide, 5, 10 or 15 frames per second
• Smooth colors with a shared palette and dithering

EXTRACT AUDIO
• Re-encode the sound as 128 kbps AAC in an M4A file, with the estimated size shown before you start

REMOVE SOUND
• Keep the picture exactly as it is, drop the audio

ROTATE & FLIP
• Fix sideways or mirrored videos, with a live preview

CHANGE SPEED
• 0.25× to 4× for slow motion or fast forward
• Voices keep their natural pitch

MERGE
• Join up to 10 videos in the order you choose
• Different sizes are letterboxed automatically

SAVE A FRAME
• Step frame by frame and save the moment as a full-resolution photo

PRIVATE AND SIMPLE
• Videos are processed on your phone with its built-in hardware encoders
• Switch to other apps while it works: progress shows in the notification
• The app has no internet access, no account and no ads
• Results go to Movies, Music and Pictures / Video Toolbox, so they show up in your gallery
• Recent exports are listed on the home screen for quick sharing

Compress to a size: pick 8, 16, 25, 50 or 100 MB, or type your own. The app chooses the resolution and compresses again if the first try is too big. If your phone’s encoder rejects a video’s size, it now drops to a lower resolution instead of failing.
