Use Letter Studio → Dunning template. Fill in sender, recipient and invoice reference, pick the 1st, 2nd or 3rd reminder example, preview on A4 and download the PDF locally.
Yes. In Document Studio → Invoice (or Credit note) enable the Kleinunternehmer toggle. VAT is omitted and the §19 UStG exemption note is added automatically.
Use Finance Studio → PayPal fees. Enter the amount you want to receive; the calculator adds PayPal buyer-protection fees (default ~2.49% + €0.35 for DE, adjustable).
Open Document Studio → Invoice. Fill seller and buyer details, line items and tax rate, preview the A4 layout, and download a PDF locally — no account required.
In Letter Studio or Document Studio templates, use Share link to copy a URL with your form state encoded. Anyone opening the link sees the same prefilled fields.
Open PDF Studio → OCR, drop a scanned PDF and run OCR. All pages are processed locally in your browser with Tesseract.js — text never leaves your device. Download the result as .txt.
Yes. New share links use compressed encoding for shorter URLs. Older btoa-encoded links are still decoded automatically when opened.
Yes. Open PDF Studio → Repair PDF. qpdf WASM rewrites xref/trailer tables locally in your browser — no upload to a server.
Yes. In Document Studio → Invoice, fill the template and use Export ZUGFeRD PDF. v1 embeds Factur-X basic XML in the PDF; validate with the E-invoice validator for full checks.
Yes. Use the project menu in the HTML Studio toolbar to save, open, and manage multi-file projects in IndexedDB on your device — nothing is sent to our servers.
After validating XRechnung or ZUGFeRD XML, failed rules show a Fix chip that opens the invoice template with the relevant field highlighted (e.g. BT-10 buyer reference).
Yes. Open the E-invoice validator (XRechnung / ZUGFeRD), switch to Batch mode, and drop multiple XML or ZUGFeRD PDF files. You get a per-file traffic light, summary table, and a ZIP with combined JSON and text reports — all locally in your browser.
In HTML Studio, open the export menu and choose Static site ZIP. You get index.html, styles.css, script.js, assets/, and a README with hosting tips for GitHub Pages, Netlify or any static host — no server upload required.
