Video Compressor, Cutter & GIF

Compress video, cut video without re-encoding, turn a clip into a GIF, change speed, merge clips and extract the audio — all offline on your phone, with no watermark and no sign-up.

Vidmin is a small video toolkit, not an editor. Pick a video, pick a tool, get a file. Nothing to learn, nothing to upload.

▸ VIDEO COMPRESSOR — REDUCE VIDEO SIZE IN MB
Make a video smaller before you send it. Three quality steps with a live size estimate, so you know roughly how many MB the result will be before you start. A phone video usually shrinks 3–6× on Medium with hardly any visible difference, and the sound track is copied across untouched. This is the fix when a clip is too large for WhatsApp, Telegram, Messenger, Zalo, Gmail or a Discord upload.

▸ VIDEO CUTTER — TRIM WITHOUT QUALITY LOSS
Vidmin cuts at keyframes and copies the original stream instead of re-encoding it. A 10-minute video is trimmed in seconds and the result is the original, frame for frame: no blur, no second compression, no long wait. Drag the two handles to keep the part you want.

▸ GIF MAKER — VIDEO TO GIF
Turn any clip into a GIF. Drag the range, pick the frame rate (5, 10 or 15 fps) and the width, export. Small enough to drop into a chat, a group thread, Slack or Reddit.

▸ VIDEO SPEED CHANGER — SLOW MOTION AND FAST FORWARD
0.25×, 0.5×, 1.5×, 2× or 4×. The picture is not re-encoded, so the quality is untouched and the pass takes seconds. The audio is stretched with the pitch kept, so a 2× clip still sounds like the same voice — or drop the audio entirely.

▸ VIDEO JOINER — MERGE VIDEOS
Put several clips together in the order you choose. Mixed resolutions and mixed orientations are handled for you.

▸ VOLUME BOOST AND NOISE REDUCTION
Lift a recording that came out too quiet by up to 8 dB without clipping it, and optionally pull down the background hiss.

▸ EXTRACT AUDIO FROM VIDEO
Save the sound track of a video as an M4A (AAC) file, straight into your Music folder.

WHY VIDMIN
• Offline. Every tool runs on your phone. Nothing is uploaded to a server, ever — the whole app works in flight mode.
• No watermark on anything you export.
• No account, no sign-in, no subscription, no paywall in front of a tool.
• Three taps from picking a video to a saved file.
• Results are written to Movies, Pictures and Music, so they show up in your gallery and your music app straight away, with a Share button on the result screen.
• Your videos are picked through the system photo picker, so the app never gets access to the rest of your storage.

FORMATS
Reads MP4, MOV, 3GP, MKV and WebM. Writes MP4 (H.264 + AAC), GIF and M4A. Every video result is written as an MP4, so putting a MOV or MKV clip through Compress also converts it into a file that plays anywhere.

Vidmin is useful for shrinking a video for WhatsApp, trimming a long screen recording down to the part that matters, making a GIF out of a funny second, slowing a golf swing down to 0.25×, joining a set of clips into one file, or pulling the audio out of a lecture recording.

FREE UP STORAGE SPACE
A handful of 4K clips is enough to fill a phone. Put them through Compress on Small, check the result in the built-in library, then delete the originals from your gallery — a long 1080p or 4K recording usually drops from several hundred MB to a few dozen.

Vidmin covers what most people actually want from a video size reducer, a video trimmer and a video to GIF converter, without a timeline, a project file or a tutorial.
