PDF and document tools
Optimize and convert PDF and office spreadsheets locally and in complete security.
Are you familiar with the situation when you need to compress a report to PDF or convert an important Excel spreadsheet to JSON, but cloud converters raise concerns about the privacy of your financial or personal data?
We offer a secure and transparent solution for your documents. Most of the file handling and data conversion processes take place directly in your browser, leaving your secrets on your device.
With us, you can easily reduce the weight of PDF files or convert tabular data between CSV, TSV, JSON, Markdown and HTML in one click, without network delays and risks of information leakage.

Certificate Generator
Create a print-ready certificate of achievement or completion — recipient name, course title, issuing organization, date and a signature line, drawn as a real vector design entirely offline.

Invoice Generator (PDF)
Fill in your business and client details, line items, tax rate and due date, then download a clean, correctly laid out PDF invoice — no signup and no cloud storage of your business data, unlike SaaS invoicing tools.
- Full invoice form: invoice number, invoice and due dates, from/to blocks (name, address, email), a currency symbol field, and repeatable line-item rows (add or remove as many as you need) with description, quantity and unit price.
- Automatic math: every line total is quantity × unit price, with a live subtotal, configurable tax rate % and grand total shown as you type and recomputed inside the generated PDF.
- A notes/payment-terms field for bank details or due-date reminders, plus an honest built-in note (and an automatic after-generation warning) about the PDF's Latin-only font when a name or address can't be rendered exactly.

- Real AcroForm introspection: text fields, checkboxes, radio groups, dropdowns and multi-select lists are each rendered with the right control.
- Optional form flattening before download, with the editability trade-off explained up front.
- Clear detection of PDFs with no fillable fields or with unsupported XFA forms.
PDF Header & Footer / Page Number Stamper

- Per-page delete with undo and per-page 90° rotation.
- Saves a new PDF with the pages in your final order — the original file stays untouched.
PDF Redactor
Draw black boxes over sensitive parts of a PDF that permanently destroy the text and image data underneath — real redaction, not a cosmetic overlay.
- High-DPI page rendering (up to 216 DPI / 3x) via pdf.js keeps redacted pages print-quality despite becoming raster images.
- Page navigator with a page strip that marks which pages currently have redaction boxes.
- Honest mixed output: pages without boxes are copied through as vector PDF content, pages with boxes are flattened to embedded JPG images.
Rotate PDF Pages

PDF to Markdown Converter
Extract a PDF's text as structured Markdown: real heading detection from font size, list detection from bullets and indent — not one flat wall of text.
- Font-size-ratio heading detection (H1/H2) against the document's median body text size.

- Instant download of the watermarked PDF with the original file untouched.
Receipt Generator (PDF)
Generate a simple sales or payment receipt as a downloadable PDF — business name, itemized list, tax, total and payment method — with a compact thermal-printer layout option, assembled entirely in your browser.
- Business name, date, a repeatable items list (name and price, add or remove rows), tax rate % and a cash/card/other payment method selector.
- Standard vs. thermal page-size toggle: thermal renders at a narrow ~80mm width with tighter line spacing and a page height that grows or shrinks to fit exactly the items you listed.
- Automatic subtotal, tax and total, a centered business-name header measured for true centering, and a closing "thank you" line — plus an honest note about the PDF's Latin-only font.
