How your files are handled
  • Your files are opened and processed inside this browser tab. They are never uploaded, and this site has no server that could receive them.
  • The tool itself loads only from adawanglili.com when the page opens. After that, it works offline.
  • Closing the tab clears your files from memory. Nothing is kept except the files you choose to download.
  • These tool pages count visits with Cloudflare Web Analytics only: the page address and loading speed, with no cookies. Your files and their contents are never sent to it.

Limitations

  • Saving creates a new PDF. Bookmarks and fillable forms are kept, but digital signatures are no longer valid.
  • To open a locked PDF, you need its password. New passwords use AES 128-bit encryption.
  • Scanned pages are images, so Read cannot extract their text.
  • Very large files depend on your device’s memory and can be slow on phones.
  • Works in current versions of Chrome, Edge, Firefox and Safari.

    Organize

    Tap pages to select them. Drag to reorder on a computer, or use the move buttons on any device.

    Select
    Selected pages (0)
    Whole layout

    Keyboard: Shift-click selects a range. Delete removes selected pages. Ctrl+Z undoes.

    Add one or more PDFs and their pages are laid out on the mat. Use the tabs to read, organize, merge, split or password protect them, then save the result. Every tool is free, works on computers and phones, and adds no watermark.

    How to do it

    1. Click Add PDFs or drop your files on the page.
    2. Pick a tool from the tabs on the right: Read, Organize, Merge, Split or Protect.
    3. Save the result. It goes straight to your device.

    Why your files stay private

    Use it for documents you would rather not hand to a stranger: contracts, HR files, bank statements and tax forms.

    Most free PDF sites send your document to their server and send a result back. This one does not. The page reads your file directly from your device, does the work in your browser with the open source libraries pdf.js and pdf-lib, and saves the result to your downloads. Nothing is uploaded, so there is nothing to store. You can test it yourself: load the page, turn off your Wi-Fi, and every tool still works.

    Questions

    Is it really free?

    Yes. There is no account, no watermark, no daily limit and no paid tier.

    Are my PDFs uploaded anywhere?

    No. All processing happens inside your browser. The site never receives your files.

    Does it work on a phone or Chromebook?

    Yes. It runs in any recent browser. On touch screens, use the move buttons in the Organize tab instead of dragging.

    Is there a file size limit?

    Only your device’s memory. Large scanned files with hundreds of pages work, but take longer on older phones.

    Is it safe for contracts, HR files and financial documents?

    Your files never leave your device, so nothing is stored on a server or seen by anyone else. That makes it a good fit for contracts, HR files, bank statements and tax forms. For extra peace of mind, turn off your Wi-Fi once the page has loaded.

    Do I need to install anything? Does it work offline?

    There is nothing to install and no account to create. Open the page in any recent browser. Once it has loaded, every tool keeps working without an internet connection.
