Resize Image for YouTube

Make a YouTube thumbnail, channel banner or profile picture at exactly the right size. Drag to frame the shot, then download.

YouTube tips

  • Thumbnails are seen small: big faces and three or four words of large text work best.
  • Avoid the bottom-right corner, where YouTube shows the video length.
  • For banners, put everything important in the centre strip; TVs show the whole image, phones only the middle.

These are each platform’s recommended upload sizes, last checked in October 2026. Platforms accept other sizes too, but then crop or scale your image themselves.

Crop or fit?

  • Crop to fill fills the whole frame and cuts off what does not fit. Drag the preview (or use the arrow keys) to choose what stays, and zoom in to frame tighter.
  • Fit whole image keeps the entire photo and fills the gaps with a blurred copy of it or a solid colour. Use it for group photos, screenshots, artwork and anything with text near the edges.

Tick several sizes to download them all at once as a ZIP, for example a square post, a portrait post and a Story from the same photo.

Getting sharp results

  • Start from the largest version of the photo. Enlarging a small image always looks soft; the tool warns you when that happens.
  • Upload at exactly the recommended size, so the platform does not resize it again.
  • Use JPG for photos and PNG for graphics with text. If a platform has a file size limit, use the image compressor afterwards.

Common mistakes

  • Letting the platform crop for you

    Upload a photo in the wrong shape and the app picks the crop, often cutting off heads or text. Crop it yourself first.

  • Text too close to the edges

    Covers and Stories are cropped differently on phones and computers, and app buttons sit over the edges. Keep text and faces near the centre.

  • Resizing an already small image

    A 400-pixel image enlarged to 1080 looks blurry. Find the original photo instead.

Frequently asked questions

What is the YouTube thumbnail size?

1280 × 720 pixels (16:9), at least 640 pixels wide, and under 2 MB as JPG, PNG or GIF. If yours is larger, run it through the image compressor.

What size is YouTube channel art?

2560 × 1440 pixels. Only the central 1546 × 423 area is visible on every device, so keep your name and text inside it.

What size is a YouTube profile picture?

800 × 800 pixels; it is shown as a circle, so keep the subject centred.

Are my photos uploaded?

No. Resizing runs entirely in your browser. Your photos never leave your device.
