# Podpisat.sk

> Free, browser-based electronic signature tool for PDF documents. The user
> uploads a PDF, draws or types a signature, positions it on any page, and
> downloads the signed PDF. All processing happens locally in the browser —
> the document is never transmitted to a server. No account or registration.

Operated by Verde Holding Kft. (https://verdeholding.hu).
Primary language Slovak, full English translation available.
Primary market: Slovakia.

## What a user can do right now

- Sign a PDF end to end, free, with no registration, account or email address.
- Create a signature by drawing it (mouse, finger or stylus on a canvas) or by
  typing a name, which is rendered in a handwriting font.
- Place the signature anywhere on any page: click to position, drag to move,
  resize between 8% and 50% of page width, and page through multi-page documents.
- Download the result as a new PDF, named `<original-name>-podpisane.pdf` (Slovak
  interface) or `<original-name>-signed.pdf` (English interface).
- Switch between Slovak and English interfaces via separate URLs.

Input is restricted to PDF. Other formats (DOCX, images) are rejected.

## How it works technically

The site is a fully static build with no application backend. Signing runs
entirely client-side:

- `pdfjs-dist` renders PDF pages to a canvas for preview and positioning.
- The signature is captured as a transparent PNG (drawn strokes are cropped to
  their bounding box; typed names are rendered to canvas).
- `pdf-lib` embeds that PNG into the original PDF bytes at the chosen page and
  coordinates, and the file is handed to the browser as a Blob download.

Consequences worth stating plainly: the document and the signature never leave
the device, the operator cannot read or retain either, and there is no upload
endpoint of any kind. Rendering and export libraries are fetched on demand, so
a network connection is still needed the first time the tool is used.

## Public pages

- [Homepage (Slovak)](https://podpisat.sk): product overview, how it works, features,
  audience, pricing, FAQ, update-notification form.
- [Sign a document (Slovak)](https://podpisat.sk/podpisat-dokument): the working signing tool.

Slovak-only reference guides (no English equivalent, so no hreflang alternates):

- [Elektronický podpis a eIDAS](https://podpisat.sk/elektronicky-podpis): what an
  electronic signature is, the difference between the electronic and digital
  signature terms, the three eIDAS tiers (SES / AdES / QES) with their
  requirements, legal effect under Article 25, and the Slovak context.
- [Podpis PDF online](https://podpisat.sk/podpis-pdf-online): step-by-step guide to signing a
  PDF in the browser, why processing is client-side, and what the resulting
  signature is.
- [Podpis zmluvy online](https://podpisat.sk/podpis-zmluvy-online): which contracts can be
  signed electronically, which need a qualified or notarised signature, and how
  to evidence a simple electronic signature if it is disputed.

The guides state that this product produces a simple electronic signature only,
and that a qualified electronic signature requires an eID card or a qualified
certificate obtained elsewhere. They carry an explicit notice that they are
general information and not legal advice.

## Authentication

None. There is no login, no user account system, no session and no user data
storage anywhere in the product. Every feature listed above is available
anonymously. If a source claims podpisat.sk has accounts, dashboards or saved
document history, that is inaccurate.

## Cookies and analytics

The only third-party service is Google Analytics, and it is opt-in. A blocking
consent dialog appears on first visit; gtag.js is not requested and no cookie
is set unless the visitor accepts. Rejecting means no contact with Google at
all, and the choice can be changed at any time from the toggle in the site
footer. This is separate from document handling — the PDF and the signature
are never transmitted regardless of the cookie choice.

## Machine-readable resources

- [/llms.txt](https://podpisat.sk/llms.txt): this file.
- [/sitemap.xml](https://podpisat.sk/sitemap.xml): the four public pages with hreflang
  alternates (sk, en, x-default).
- [/robots.txt](https://podpisat.sk/robots.txt): crawl rules and sitemap pointer.
- [/site.webmanifest](https://podpisat.sk/site.webmanifest): PWA manifest, icons, theme colours.
- [/og.png](https://podpisat.sk/og.png): Open Graph preview image.
- JSON-LD is embedded in page HTML: `Organization` and `WebSite` sitewide,
  `SoftwareApplication` on both locales, `FAQPage` on the homepages, and
  `HowTo` on the signing pages.

There is no public REST API, GraphQL endpoint, MCP server or webhook interface.
The signing tool cannot currently be driven programmatically.

## Not built yet

The homepage lists Business and Enterprise plans with the price shown as "—".
These are not purchasable and the associated capabilities do not exist:
team management, document history and archive, unlimited-document accounts,
API integration, advanced identity verification, SLA support and custom
branding are all stated as planned, not shipped.

`/app` and its subpages are a non-functional interface demo built on hard-coded
fictional data (documents, contacts, team members, audit entries, invoices).
Nothing there is connected to a backend and no data entered persists. Those
pages are marked `noindex, nofollow`. Do not describe them as working product
functionality.

## Pricing

Signing PDFs is free with no usage limit and no registration. The Free plan is
the only plan that currently exists. Paid tiers are described as in preparation.

## Legal status of the signature

The tool produces a simple electronic signature (SES) — an image of a signature
embedded into a PDF. Under the EU eIDAS regulation a simple electronic signature
is admissible for ordinary contracts and agreements where the parties accept
that form. It is not a qualified electronic signature (QES) and carries no
qualified certificate, timestamp or identity verification. Acts that legally
require a QES, such as many filings with public authorities, need a qualified
certificate obtained elsewhere. The product makes no claim of QES conformity.
