Look for the original logo file first
Look for an official transparent PNG or vector version of the logo. A vector file stores shapes that can be resized without turning their outlines into enlarged pixels. SVG, EPS and PDF files can contain vector artwork, but the extension alone does not guarantee it: a PDF can also contain a flat image.
If the logo came from a website, check the brand resources or ask the owner for the approved file. This also helps you avoid working from an outdated mark or an unofficial color.
Choose a raster source with enough detail
When no vector file exists, use the largest clean PNG or JPEG available. Do not enlarge a tiny logo before removing the background. Enlarging makes the same edge pixels bigger and can make compression marks more obvious.
A simple logo on a flat, contrasting background is easier to separate. Light lettering on white or a shadow baked into the image needs closer inspection because part of the logo may blend into the background.
Remove the background, then inspect the letters
For a logo displayed as a normal web image, you can try ClickCutout with PNG selected. Download the result and compare it with the original. Check every letter, small symbol and thin stroke, including the holes inside A, B, P and R. Automatic background removal can mistake detached lettering or small marks for background.
If parts of the logo disappear, use the official transparent file or an editor with a background-color selection tool and a mask. Keep white shapes that belong to the logo when removing a white background. Adding an outline to hide a damaged edge changes the mark itself.
Test the logo on light and dark colors
Place the logo over white, near-black, and one brand color. A light fringe is easiest to see on a dark background. Missing dark pixels show up quickly on a pale background.
Judge the logo at its real display size as well. A tiny irregularity that is invisible in a navigation bar may still matter on a large poster or presentation title slide.
