When to Update a Logo in a PDF Rebranding is the most common reason. When your company adopts a new logo, the templates you already rely on — letterheads, invoices, proposal shells, report covers, handouts — still carry the old mark. Rather than rebuilding every PDF from scratch, you can erase your previous logo and drop in the new one with a PDF editor. This is meant for your own documents and your own branding: use it to refresh materials you own or are authorized to update, not to remove or replace another party's logo on work that isn't yours.
Clearing a Logo from a Letterhead Letterhead logos usually sit in a consistent position on every page — top-left, top-center, or spanning the header band. Draw your selection box to cover the whole logo, including any tagline beneath it. For white letterheads, White fill mode gives the cleanest result. If the header has a colored band, use Auto Match to blend the erased area with the surrounding color. Check every page, since many documents use a different header on page one versus the pages that follow.
Adding Your New Logo Once you've downloaded the cleaned PDF, open it in ConvertKr's PDF Editor and use the image tool to place your new logo exactly where the old one sat. This two-step workflow — clear the old logo, add the new one — is often faster than editing the original source file, which you may no longer have. The result is an updated template that matches your refreshed brand across every page.
