Free image and video resizer

Resize images and videos

Resize photos, screenshots, and short videos to an exact size, including App Store screenshot and app preview sizes. Keep proportions, pad with a background color, or crop to fill. Everything runs in your browser, so nothing is uploaded.

Files are resized on your device and never uploaded.

Choose a preset, then use the swap button for landscape. App Store Connect also accepts a few older sizes, listed in Apple’s screenshot specifications and app preview specifications.

Keep proportions, pad, or crop

  • Keep proportions: the picture shrinks or grows until it fits inside the size, so one side may come out smaller than you typed. Leave width or height empty to set only the other.
  • Pad to exact size: the whole picture fits inside, and the leftover space is filled with your background color, or left transparent for PNG and WebP.
  • Crop to fill: the picture covers the whole size and the edges that don’t fit are trimmed equally from both sides.

How video resizing works

The browser plays your video into a canvas at the new size and records that canvas as a new file, with the original sound if you keep it. That is why a 30-second video takes about 30 seconds, and why the tab should stay open and in front until it finishes. Video sizes are rounded down to even numbers, which most video formats need.

Frequently asked questions

Does this resizer upload my photos or videos?

No. Images and videos are resized in your browser on your own device. They are not uploaded, saved, or sent to a server.

What size should App Store screenshots be?

For iPhone, use 1320 × 2868 pixels for the 6.9-inch display, or 1284 × 2778 for the 6.5-inch display. For iPad, use 2064 × 2752 for the 13-inch display. Swap the numbers for landscape. App Store Connect scales the largest size down for smaller devices.

What size should an App Store app preview video be?

Use 886 × 1920 pixels for iPhone and 1200 × 1600 for iPad, or the same numbers swapped for landscape. App previews can be 15 to 30 seconds long.

Why does resizing a video take as long as the video?

The browser plays the video and records a new copy at the new size as it plays. Keep the tab open and in front until it finishes, because browsers slow down tabs in the background.

Is the resized video an MP4?

When the browser can record MP4, as current Chrome, Edge, and Safari can, the video is saved as MP4. Otherwise it is saved as WebM. The tool shows which one before you start. The video always has a sound track, which is silent when you turn sound off.

Can I resize several images at once?

Yes. Choose or drop several images and they are all resized with the same settings. Download them one by one or all together. Videos are resized one at a time.

Why won’t my HEIC photo or MOV video open?

The tool can only open files your browser can show. Safari opens iPhone HEIC photos and HEVC videos; some other browsers can’t. HEIC photos are saved as PNG, JPEG, or WebP. In Chrome, Edge, or Firefox, use the HEIC to JPG converter first.
