Three steps, right in your browser
Choose your clip
Drop an MP4, MOV or WebM from your phone or computer and pick the part to slow down.
Set the speed
Drag the speed slider to 0.5× or 0.25×. The preview plays at that speed so you can feel it.
Export
Crop to 9:16 if it's for Reels, keep or replace the sound, and download an MP4 up to 4K.
Why make it here
Any speed down to 0.25×
Pick exactly how slow — the preview plays at that speed.
Sound that stays natural
Slowed voices keep their normal pitch instead of turning deep.
Tells you how smooth it'll be
It reads your clip's frame rate: 60 fps and slow-mo clips come out silky. Optional Smooth motion (beta) can fill in frames for simple, steady movement.
Dreamy in one tap
The Dreamy slow-mo recipe sets 0.5×, a warm look, a blurred 9:16 background and soft fades — tap it again to undo.
Framed for Reels
Crop to 9:16, 4:5 or 1:1, or keep the whole shot with a blurred background.
Private
Made in your browser — your video never leaves your device.

The leap, the giggle, the chase.
Questions, answered
Choose your clip, pick Speed, drag the slider below 1× (for example 0.5×) and export. The preview plays at the new speed before you download.
Yes. You get 5 free exports a day, up to 4K, with a small tooljin.com watermark. Pro and Business are unlimited with no watermark.
No. The original sound is stretched to match and keeps its normal pitch, so voices don't turn deep. You can also switch the sound off or add music.
Down to 0.25×, a quarter of the original speed. For slow motion on just one moment, try the Velocity or Bullet-time speed ramps.
It depends on how it was filmed. A clip shot at 60 fps or in your phone's slow-mo mode slows down silky smooth. A normal 30 fps clip slowed to 0.5× has 15 real frames a second, so the motion steps a little — the tool tells you this before you export, and the optional Smooth motion (beta) can fill in frames for simple, steady movement.
No. The slow motion is made on your own device, so the video never leaves it.
