Convert HTML to PDF.

Turn a saved web page into a PDF you can share or archive — without a single file ever leaving your device.

Not uploaded — nobody sees it Scripts are stripped for safety No watermark, ever No subscription or account
Your file is never uploaded — it’s processed right here in this browser tab, on your device. There’s no server involved, so we never see it, copy it or keep it.
How it works

Three steps, no waiting on a server

Altto's HTML to PDF tool works right in your browser tab, so there's no upload queue and no “processing your file” spinner tied to someone else's servers.

01

Add your HTML file

Drop in a saved .html or .htm file.

02

Convert

Altto lays the page out as a PDF, locally, paginating automatically.

03

Save your PDF

Get back a PDF version, ready to share or archive.

Why this runs in your browser, not on a server

An HTML file can contain anything from a saved receipt to an internal report — not something you’d want sitting on a stranger’s server just to make a PDF. Altto skips that step completely — there’s no server for it to go to.

  • Nothing is uploaded, everEvery file is read and converted by code that runs in this browser tab, because there’s no server on the other end. That also means we can’t see it, copy it or keep it.
  • No account, no email wallConvert as many files as you like without signing up or handing over an email address.
  • Scripts stripped automaticallyAny <script> tags and inline event handlers are removed before rendering.

files stored on our servers. There’s no server involved at all — the PDF is built once, then everything happens locally.

FAQ

Frequently asked questions

The practical details on what this tool can and can’t do. Converting a Word document instead? See Word to PDF.

Is the text in the PDF selectable and searchable?
Yes — Altto draws real text into the PDF rather than a screenshot of the page, so you can select, search and copy it afterwards, and the file stays small.
Will external images and styles show up?
Images with a normal web address usually load, but stylesheets and fonts the page links to externally may not always be fetched — inline styles carry over reliably.
Is my file uploaded anywhere?
No — nothing is ever uploaded. The HTML is read and converted entirely inside this browser tab. There's no server involved at all, so there's nothing for Altto to see, copy or keep.
Is it safe to convert an HTML file from someone else?
Altto strips any <script> tags and inline event handlers before rendering, so scripts in the file can't run — but only convert files you trust the content of.
Can I convert a live web page by URL?
Not directly — save the page as an .html file first (most browsers offer “Save Page As”), then upload it here.
How does pagination work?
Content flows automatically onto as many A4 pages as it needs, based on the page's height.
Do you keep a copy of my file?
No. There's no upload, so there's nothing on our side to keep. See the Privacy Policy for details.
