Read this before you upload anything anywhere: on No Ads PDF, there is nothing to upload to.
Merge, split, compress, convert, edit and sign PDFs — free, with no ads, no popups and no watermarks, and 100% in your browser. Your files never leave your device.
No tool matches that search.
Pick from the 30 tools above — merge, split, compress, convert, edit and more.
Tap “Choose Files” or drop files into the box. They are processed on your device, never uploaded.
Run the tool and download your finished file straight from the page.
No, never. No banner ads, no popups and no sponsored results — and we never sell your data. One honest exception: the site uses Google Analytics to count visitors and see which tools get used most. That's the only tracking here — and your PDF files are still never uploaded; every tool runs in your browser.
Yes. All 30 tools are free to use, with no ads, no account, no sign-up and no usage limits.
No. Every tool runs 100% in your browser using JavaScript. Your files are processed on your own device and are never uploaded anywhere.
Yes — because nothing is uploaded, no copy of your document ever leaves your device. There is no server copy to leak, keep or delete; when you close the tab, the file exists only where you saved it.
Only two tools genuinely need a server-side engine: OCR PDF (text recognition) and PDF Summarize (an AI language model). Those two say so honestly in the app instead of faking a result. The other 28 tools — including Protect PDF and Unlock PDF, which do real encryption and decryption in your browser — run fully on your device.
Conversions to and from Word, Excel and PowerPoint produce real .docx, .xlsx and .pptx files, but they are text-based: the text carries over, while layout, images and tables are not preserved.
Yes. No Ads PDF works in any modern mobile or desktop browser — just open the page, pick a tool and choose your files. For the file picker to open reliably, use Chrome rather than an in-app viewer.
