ImgWrench's YouTube watermark maker turns your logo into the square video watermark YouTube shows on your videos: a transparent PNG, at least 150×150 pixels and under 1MB, as YouTube's branding help asks.

How to make your YouTube watermark

  1. Drop your logo into the tool above.
  2. Turn on Auto-trim to remove empty space, then choose Contain to keep the whole logo.
  3. Download the PNG; it's 300×300 and checked against 1MB.
  4. In YouTube Studio, go to Customisation, then Branding, and upload it as the video watermark.

YouTube's watermark rules

YouTube's "Manage your channel branding" help page asks for a square image of at least 150×150 pixels, less than 1MB in size. It lists no file formats; PNG keeps a cut-out logo transparent over your videos.

Tips for a watermark that reads

  • Bold and simple. Shown small over video, thin lines vanish.
  • Fill the square. Auto-trim removes empty space so the logo isn't tiny.
  • Transparent background. No box over your video.

Why ImgWrench

  • The right shape. Square, transparent, under 1MB.
  • Auto-trim built in. No wasted space around your logo.
  • Private by design. Your logo never leaves your device.

Frequently asked questions

How do I make a YouTube watermark?

Drop your logo into the tool above. If it isn't square, choose Contain to fit it with transparent padding, or Crop to pick a part. The tool exports a 300×300 PNG, twice YouTube's 150×150 minimum, and checks it against the 1MB limit. Upload it in YouTube Studio under Customisation, Branding, Video watermark.

What size should a YouTube watermark be?

YouTube asks for a square image of at least 150×150 pixels and less than 1MB. It doesn't list file formats. ImgWrench exports 300×300, our own pick at twice the minimum, so the watermark stays sharp on large and high-density screens while staying far below 1MB.

Can a YouTube watermark have a transparent background?

The tool keeps transparency in the PNG it makes, so a cut-out logo has no box around it over your video. If your logo sits on a solid background, remove the background first in an image editor. A JPG option is there too, but JPG can't be transparent and fills the background with white.

Why does my watermark look small or blurry?

The watermark appears over your videos at a much smaller size than the file, so fine detail and small text disappear. Use a simple, bold version of your logo, fill most of the square, and start from an image larger than 300 pixels. The Auto-trim option removes empty transparent space around the logo for you.

Do I need a different image for my YouTube profile picture?

It can be the same logo, but it's a separate upload with a different shape on screen: the profile picture renders at 98×98, a different size from the watermark. The YouTube profile picture resizer makes it from the same file, so your channel's branding matches.

Are my images uploaded anywhere?

No. Everything happens in your browser: ImgWrench resizes your logo on your own device, and it is never sent to a server or stored anywhere else. You can confirm this yourself by opening your browser's network tab while you use the tool and checking that no request carries your image data.
