Before you start

Gather the logo files you can actually access: an SVG, a high-quality PNG, or at minimum a screenshot shown at the size where people normally see it. For an audit, working copies are enough. Use image tools that run locally in your browser when possible, so the original file stays on your device. Do not assume an ugly logo is only a matter of taste; separate legibility, color, scaling and format problems before changing the design.

Step-by-step instructions

1. Check narrow and distant visibility

Export or display the mark at the smallest realistic size: an app icon, a browser favicon, a social profile image, or a small badge in a video call. Note where edges disappear, letters close up, or details merge. An ugly impression often comes from a design that was made only for large screens.

2. Check contrast and color pairs

Sample the main text color and the background behind it. Test the pair in a contrast checker against the WCAG AA threshold for ordinary text and AA or the large-text pass for bold headings. If the logo uses thin strokes, low contrast makes the mark look weak even when the colors feel acceptable at full size.

3. Check shape and typography problems

Cover the icon and read the wordmark alone, then cover the wordmark and look at the icon alone. Look for competing curves, near-miss alignment, letterforms that touch, or outlines that were added to fix contrast instead of simplifying the shape. Write down only issues that affect understanding or reuse, not subjective likes.

4. Check file limitations

Resize a PNG copy to common export widths and notice where it becomes soft or pixelated. If only a flattened image exists, record that as a production problem: a redesign plan may need a vector source or a redraw before the mark can work across screens and print surfaces.

Check the output

Place the saved test versions side by side at the same scale: full size, favicon size, and a mockup scene if available. The result is clear when the wordmark remains readable in every intended use. If a contrast pair fails the chosen target, or the PNG loses meaning at a required size, treat that as a confirmed audit finding rather than an aesthetic complaint.

Pixel-based tools cannot prove that an SVG path will remain clean in every renderer. Check the generated PNG or visible preview only. A resize pass on a raster file tells you about that copy, not about a future source file.

Common problems and next steps

Logo looks fine alone but bad in the header

Compare the same mark against light, dark and mid-tone backgrounds. A transparent PNG with a dark outline may survive every background but look heavy; a monochrome SVG without enough foreground contrast may vanish. Keep one tested version for each common background category.

Wordmark is readable but the icon is noisy

Simplify the icon before changing the wordmark. Remove unnecessary outlines, gradients and tiny details that fail the favicon test. The next step is a redraw with fewer shapes, not a louder color.

Colors fail only one format

Prepare a flat contrast-approved version for small or screen-only use instead of refusing a brand palette. Keep the decision visible in the audit: one mark may need a simplified color treatment for icons and video overlays.

No vector file is available

Mark it as a source-file gap in the redesign plan. A clean redraw may be necessary, but do not promise automatic vectorization or AI repair. The most useful next action is to trace the core shape deliberately with a local editor and compare the result at small sizes.
