Logo Centerer

Uploads a logo PNG and places it centered within a new canvas of your chosen width and height, filling the surrounding area with transparency, without scaling or distorting the logo's own pixels. A free online tool from Staaarter, right in your browser.

Overview

Introduction

This tool centers a logo within a canvas of any size, entirely in your browser, without scaling the logo itself.

It's a fast way to standardize logo assets to a consistent canvas size before use in a template, app icon slot, or design system.

What Is Logo Centerer?

A client-side canvas-alignment tool that places a logo's exact original pixels in the middle of a new, independently-sized canvas.

It's the center-anchor case of a more general canvas-size-change operation, applied specifically to logo uploads.

How Logo Centerer Works

The tool computes the offset needed to place the logo's own width and height exactly in the middle of the requested new canvas dimensions, then copies the logo's pixels to that offset, leaving everything else transparent.

If the new canvas is smaller than the logo in either dimension, the centered logo simply extends past the canvas edge and gets cropped there.

When To Use Logo Centerer

Use it to fit a logo into a fixed-size slot (an app icon frame, a social media profile image, a template placeholder) while keeping it centered.

It's also useful for standardizing a batch of differently-sized logo exports to one consistent canvas size.

Features

Advantages

  • Runs entirely client-side; your logo file is never uploaded anywhere.
  • Keeps the logo's original pixel resolution and aspect ratio untouched, unlike a resize.
  • Produces a precise, mathematically centered result every time.

Limitations

  • It doesn't scale the logo to fit — if the target canvas is smaller than the logo, parts of it will be cropped rather than shrunk.
  • Only supports centered alignment; other anchor positions (like top-left) aren't exposed by this specific tool.

Examples

Fit a logo into a square app icon slot

Input

A 300x150 wide logo, target canvas 400x400

Output

A 400x400 PNG with the logo centered and transparent padding on top and bottom

The wider logo is centered vertically within the extra height of the square canvas.

Standardize a logo to a fixed canvas

Input

A 250x250 logo, target canvas 250x250

Output

The same logo, unchanged, since the target size matches its own

When target dimensions equal the source size, the result is effectively the original logo.

Best Practices & Notes

Best Practices

  • Choose a target canvas at least as large as the logo's largest dimension to avoid unwanted cropping.
  • Run the space remover first if your source logo already has uneven built-in margin, so centering measures from its true visible bounds.

Developer Notes

The lib function is a thin re-export of the already-shipped centerPng from the base centerer tool (itself the center-anchor case of the general canvas-size-changer), since a logo is just a PNG once it's uploaded — no new alignment math was needed here.

Logo Centerer Use Cases

  • Fitting a non-square logo into a square app icon or avatar slot
  • Standardizing a batch of logo exports to one consistent canvas size
  • Centering a logo before adding a border or background that expects it centered

Common Mistakes

  • Choosing a target canvas smaller than the logo and being surprised parts of it get cropped instead of scaled down.
  • Forgetting to trim an uneven existing margin first, which can make the logo look off-center even after this tool runs.

Tips

  • Combine with the space remover beforehand if your logo has inconsistent transparent margin baked in.
  • Use a square target canvas for logos headed to profile picture or app icon slots, which are almost always square.
