Organize PDF

No. The whole operation runs in your browser with pdf-lib and pdf.js. Open your browser’s Network tab while you work and you’ll see no request carries your file data. Your PDF never leaves your device.

Each page is rendered to a hidden canvas and we measure how much non-white ‘ink’ it has, ignoring the margins so a stray page number doesn’t count. Pages below a small threshold are flagged as blank and pre-selected — but nothing is deleted until you confirm, so a false match is never destructive.

No. The pages you keep are copied exactly as they are — nothing is re-encoded, recompressed or rasterised. The new PDF is page-for-page identical to the originals you kept.

Yes. Drag the thumbnails into any order, or use the up and down arrows. The new document follows the order shown. You can also duplicate a page by keeping it twice.

No daily cap or account is required. Pages are rendered in your browser’s memory, so very large PDFs depend on your device’s RAM, but there’s no artificial task limit like the upload-based tools impose.

Encrypted PDFs must be unlocked first so their pages can be read and rendered. Remove the password, then add the file again.
