Zoho Invoice

Free invoicing with estimates, reminders and a client portal attached

Fills in a clean invoice in the browser and downloads it as a PDF.
One form, no account: your details, their details, line items, tax, a logo, and the PDF downloads immediately. Currency, date format and the wording of every label can be edited, which matters if you invoice outside the United States. It produces the document and nothing else — it will not remember the client, number the next invoice or tell you whether you were paid.
AltFTool does this too
If you would rather not leave the site, Invoice Generator covers the same job here — free, no account, and it runs in your browser.

Works the moment the page loads. No account, no email, no trial. It generates a document and forgets it — no client list, no numbering, no record of what was paid.
Yes. Invoice Generator sends your input to its own servers to process it. That is fine for public material; for anything containing personal data, use one of the on-device tools instead.
