Frequently asked questions

Is UsePDF.online really free?

Yes. Every tool on the site can be used without an account, without a watermark and without a daily limit. Running costs are covered by advertising and optional supporter contributions.

Are my files uploaded to your server?

No. The PDF and image tools run inside your own browser, so the files you choose are processed on your device. The only things that reach our server are normal page requests and anything you type into the contact form.

Does it work on a phone or tablet?

Yes. Every tool has a file picker as well as drag and drop, and the layouts are designed for small screens first. Very large PDFs depend on your phone's memory, so split big jobs into smaller batches.

Which tools need an internet connection?

The page and the processing libraries load from the internet the first time you open a tool. After that the conversion itself happens on your device, but you still need to be online to open the page.

Can I edit the original text inside a PDF?

The PDF editor adds new content on top of a page: text, images, shapes, highlights, drawings and signatures. It does not reflow or rewrite the original text, because PDFs do not store text as editable paragraphs. Use Whiteout to cover something and type the replacement above it.
