By using Altto, you agree to the following:
The service
Altto is a set of free tools for PDFs, images, documents and everyday tasks, provided “as is” and free of charge. Every tool is free to use. Every tool runs in your browser. Results depend on the file you start with: a converted document may not match the original exactly. See our formatting guide for what to expect from PDF to Word.
Your responsibility
You are responsible for the files you convert and for having the right to use and edit their content. Don't use Altto to process content you don't have permission to handle, or for any unlawful purpose.
Results, estimates and advice
Some tools give results you should check before relying on them:
- AI tools (summaries, translations, transcripts, upscaled images, background removal) can make mistakes. Check anything important against the original.
- The IQ Test gives an estimate for personal interest. It is not a clinical or official IQ score.
- The BMI Calculator is general information, not medical advice. Talk to a GP or other health professional about your weight or health.
- The Passport Photo Checker checks the rules it can measure. It can’t guarantee that a passport office will accept a photo.
- The Invoice Generator and MTD Spreadsheet Maker help you keep records. They are not tax, legal or accounting advice; check GOV.UK or an accountant for your situation.
- The AI Image Checker reports what a picture’s own data says. A picture with no data, or with its data removed, may still have been made with AI.
No warranty
Altto is offered without warranties of any kind, express or implied. We aren't liable for any loss or damage arising from the use of, or inability to use, this tool, including data loss, formatting differences, or missed deadlines, to the fullest extent permitted by law. Nothing in these terms limits your statutory rights as a consumer.
Advertising
This site may display advertisements served by third-party networks, such as Mediavine, to support free access to the tool. Ads are separate from Altto's own content, and we don't control their specific content. See our Privacy Policy for how advertising cookies work.
Intellectual property
The design, text, and code of this site belong to Altto. The PDF-reading and document-building libraries used to power the converter are open-source and used under their respective licences.
You may not copy, republish, or reuse the site's own code, design, or text — including the PDF to Word converter — on another website, app, or product without written permission. Using the tools themselves is always free.
Changes
These terms may be updated occasionally; continued use of the site after a change means you accept the updated terms. Material changes will update the date at the top of this page.
