For individuals and small businesses handling forms, contracts, reports, and other paperwork, Lumr brings common PDF tasks together in a browser-based workspace. Edit text and images, annotate files, fill forms, add a signature, merge or split documents, rearrange pages, compress files, and convert between PDF and formats such as Word, Excel, PowerPoint, JPG, and PNG. No software installation is needed, and the site can be used in a mobile browser. Lumr also includes AI tools to summarize a PDF, translate it, or answer questions about its contents. Ready-made legal and business templates—such as leases, bills of sale, and powers of attorney—and fillable US government forms can help with everyday document preparation. It may suit people who want document editing, conversion, signing, and form-filling tools in one online service; its templates are not a substitute for legal advice.
