Turn a locked PDF into an editable Word document.

Drop in a PDF and Altto rebuilds its text as a real .docx file you can edit in Word, Google Docs, or Pages — without ever sending the file to a server.

Your PDF is never uploaded — it’s read 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 does the parsing and file-building 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 PDF

Drag it into the drop zone or pick it from your files. Altto checks it's a readable PDF before doing anything else.

02

Text is extracted, page by page

A PDF-reading engine loaded into the page walks each page and pulls out its text and layout in order.

03

Save the .docx

Altto rebuilds the text as a Word file and hands it to you to save — open it in Word, Docs, or Pages right away.

Why this runs in your browser, not on a server

Most free converters ask you to upload a file to a server, wait, then download the result — and your document sits on someone else's disk in the meantime. Altto skips that step completely: there's no server for your file to go to, so there's nothing for anyone to see or store.

  • Nothing is uploaded, everThe PDF is opened and converted using 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.
  • Text-based, not a scan guesserAltto reads the real text layer in your PDF, so headings, paragraphs, and word order come through cleanly.

files stored on our servers. There’s no server involved at all — the conversion library is loaded once, then everything happens locally, right here in your browser.

FAQ

Frequently asked questions

The practical details on formats, limits, and what Altto can and can't do. For more, see our guides.

Will my formatting and images come through?
Altto focuses on getting your text out cleanly — paragraphs, line breaks, and reading order are preserved. It doesn't currently recreate embedded images, columns, or exact pixel layout, so a heavily designed PDF (brochures, forms) will convert as clean text rather than a visual match. See our guide on keeping formatting intact for tips.
Does it work on scanned PDFs?
Yes. If the scan already has a text layer (for example, one your scanner or Adobe Acrobat has run OCR on), Altto reads it directly. If it doesn't, Altto automatically detects the missing text and runs its own built-in OCR in your browser before converting.
Is there a file size or page limit?
Altto is comfortable with everyday documents — contracts, essays, reports, resumes. Very large files (dozens of MB or many hundreds of pages) can be slow because everything runs on your device's own processor rather than a server farm.
Is this really free?
Yes. Altto is supported by advertising rather than subscriptions or per-file fees, and there's no limit on how many PDFs you convert.
Do you keep a copy of my document?
No — there's no server on our side at all, so there's nothing to keep. See the Privacy Policy for details on the limited, non-document data (like basic analytics or ad cookies) this site may use.
