your privacy matters
better pdf is built with privacy as a core principle. your files never leave your device.
last updated: january 26, 2026
the short version
better pdf processes all files entirely in your browser. your files never leave your device and are never uploaded to any server. we don't collect, store, or have access to any of your documents.
how it works
all pdf processing happens locally on your device using javascript. when you upload a file to better pdf, it is processed entirely within your web browser using client-side technologies. at no point is your file transmitted over the internet or stored on any external server.
what we don't collect
- your pdf files or any documents you process
- the contents of your files
- personal information from your documents
- file names or metadata
what we may collect
we may collect anonymous, aggregated analytics data to improve our service:
- page views and general usage patterns
- browser type and version
- device type (desktop/mobile)
- country-level geographic data
this data is anonymized and cannot be used to identify individual users or their documents.
local storage
we use your browser's local storage to save your preferences (such as theme settings) and recently used files list. this data is stored only on your device and is not transmitted to any server. you can clear this data at any time through your browser settings.
third-party services
better pdf may use third-party services for hosting and analytics. these services have their own privacy policies. we do not share any of your document data with third parties because we never have access to it in the first place.
security
because your files are processed entirely in your browser and never uploaded to our servers, the security of your documents depends on your own device and browser security. we recommend keeping your browser updated and using trusted devices when working with sensitive documents.
changes to this policy
we may update this privacy policy from time to time. any changes will be posted on this page with an updated revision date.
