Resize a video for Pinterest: 9:16 or a classic 2:3 Pin
Drop a video above, keep 9:16 or pick 2:3, and choose Crop or Pad. You get an MP4 that Pinterest takes on the web and in the app.
In short
- Pinterest recommends 9:16 for video Pins, and that shape is already set here.
- The classic 2:3 Pin and 1:1 square are one tap away, and Pinterest accepts both.
- Pinterest takes videos from 4 seconds to 5 minutes, so a phone MP4 fits.
- The tool always writes an MP4, which Pinterest takes on the website and in the app.
- Nothing is uploaded. The tool runs in this browser tab, so your video stays with you.

What Pinterest asks for
From Pinterest's Pin specs page, read in September 2026.
- Pinterest takes MP4 and M4V on the website, and MP4, MOV and M4V in the app.
- Pinterest recommends 9:16, because a tall Pin fills more of a phone screen.

Crop or pad?
Crop fills the new shape and cuts the edges off. Pad keeps the whole picture and adds bars.
- Crop is the better choice when the person or the product sits in the middle of the frame.
- Pad is the better choice when nothing may be cut, such as text, a logo or a wide product shot.
- You pick black or white bars for padding.
- The preview shows the crop window and how much of the picture you keep.
What a crop keeps
Crop sizes from a 1080p clip. The crop is taken from the centre and never blown up.

Limits of a browser tool
Everything runs on your own device, so your device sets the limits.
- File size: up to 500 MB runs comfortably. Bigger files may run out of memory.
- Speed: the engine uses one processor core, so a long re-encode takes minutes.
- First run: the engine downloads once, about 32 MB. After that it starts fast.
- Phones: it works, but a laptop is faster and has more memory.
