Before you start

A logo change usually means working from an existing image file rather than a live institutional system. Open the current mark on a known device and check the file you actually have: PNG, SVG, WebP or another common format. Note the visible size, background and any text or seal details that need to remain legible when the mark is smaller.

Keep a copy of the original file before editing. The process described here is local to your browser, but only treat that as confirmed if the tool you are using clearly says it does not upload files. If an interface asks you to sign in or send the file to a service, stop and choose a local tool.

Step-by-step instructions

1) Select the current logo file in the tool without dragging it into an email, chat or unknown web form. Use a file picker that names the selected item before processing starts.

2) Choose the working format. Keep SVG as vector when available. Use PNG or WebP for a source that is already rasterized, and avoid enlarging a small raster image more than a little.

3) If you only need to compare options, place the old and candidate versions side by side or use a before-and-after slider. Do not claim a candidate is official unless it comes from an authorized source.

4) Test the candidate on the backgrounds where it will appear. A mark can look correct on white and lose contrast on dark or busy surfaces. Try a solid light background and a solid dark background before deciding.

5) Export at the sizes you actually need. Start from the largest required version, then produce smaller copies. This order usually gives sharper small results than making one export and stretching it.

Check the output

Open the exported file on a separate screen or application from the one used to create it. Check the smallest expected size, such as a browser tab or a print header. If lettering, a seal or fine lines disappear at that size, simplify or scale the test rather than assuming the finished use will be forgiving.

Confirm the format matches the destination: SVG or high-resolution transparent PNG for screen and document use where supported, WebP where the platform accepts it, and a separate favicon-sized file where a browser icon is needed. Do not assume one file works everywhere.

Common problems and next steps

If the upload is rejected, check that the extension and actual contents match. An SVG saved as plain text or a renamed image can fail even when the filename looks correct. For privacy, use a tool that states files stay on the device.

If the export looks blurry, return to the largest source version and export downward. For a complex mark, test a simplified arrangement or a single-color variant at small sizes. Keep the original and each tested export labeled by size and date so the change remains reversible.

When the file is ready, share it through the destination's own approved process rather than by direct message. If there are branding or accessibility rules from the institution, compare the candidate against those requirements before publication.
