The core toolset covers the routine jobs: editing text and images in place, filling and signing forms, adding or removing pages, headers and footers, search and replace, merging, protecting, cropping, and running OCR on scanned files. Conversion is handled both ways, including PDF to Word, PDF to JPG and HTML to PDF. On top of those utilities, GoPDF adds AI features. AI Chat with PDF lets you ask questions about a document instead of reading it end to end, and the AI quiz builder turns source material into tailored questions — useful for teachers, trainers and students. An invoicing tool rounds out the set for small businesses that want to create and manage invoices alongside their documents. Everything runs in the browser with no installs and no sign-up required for basic tasks, and there are mobile apps for converting PDFs on the go. The company states that files are protected with SSL encryption and are not stored beyond your session, and support is advertised as available around the clock. A free plan covers core features while premium plans unlock advanced tools and higher usage limits. **Pricing & Plans:** Freemium.

You start by describing the document you want — an invoice, resume, contract, report, proposal, quote or letter — and the platform assembles a structured, downloadable PDF. A library of templates is included so you can begin from a professional layout and adjust it rather than designing everything from scratch. Typical workflows include generating business documents without manual formatting, customizing ready-made templates, and standardizing recurring paperwork such as receipts, product requirement documents, reports and standard operating procedures. Everything is done in the browser: you preview the result online and download it when it looks right. The pricing is tiered by output volume. A free plan covers occasional needs with a small monthly quota, while Pro and Team tiers raise the number of documents you can generate each month for regular professional or high-volume business use. Exact quotas and prices are listed on the official pricing page. **Pricing & Plans:** Freemium with tiered plans by monthly output volume: a Free plan for occasional use (about 5 documents per month), a Pro plan for regular professional output (about 300 per month) and a Team plan for higher-volume business use (about 1,500 per month).
