PDF tools

Add page numbers to a PDF and see them land before you commit: five formats, nine positions, any start number, and a cover you can leave bare. The preview restamps as you tweak.

Chat with a PDF in ordinary words. Answers cite the page and show a snapshot of the passage they came from.

Compress a PDF by re-encoding the pictures inside it, down to a KB ceiling if a form demands one. Text stays sharp.

Crop a PDF by dragging a box or typing margins in millimetres. Fit to content finds the ink, sideways pages are cut on the right edge, and any page can keep its own box.

Scan paper with a phone camera and get back a straight, readable multi-page PDF: auto edge detection, per-page looks, a stain eraser, optional searchable text.

Fill and sign a PDF, or click a line of printed text and retype it. Whiteout, highlight, shapes and a signature you draw, type or upload sit in one toolbar.

Flatten a filled PDF form so the answers become part of the page. Every field is listed first, and the ones that cannot be baked, like an empty signature, are named.

Image to PDF for JPGs, PNGs and phone photos: one picture per page or stacked, A4 or Letter, in the order you drag them, with the PDF shown before you save it.

Merge PDF files into one document in the order you set, with each file's bookmarks and filled form fields carried across and a bookmark added for every file.

Organize PDF pages as a grid of thumbnails you can drag: rotate a sideways scan a quarter turn, duplicate a page, drop the cover sheet, or append a second file, then save it.

Convert PDF to JPG or PNG at 1x, 2x or 3x resolution, one image per page. Narrow it to a range like 1-3, 5 and take the results singly or as one ZIP.

Extract text from a PDF the moment it lands, copy it or save a .txt named after the file, and see which pages are scans with no text to give.

Password protect a PDF with AES-256 encryption from qpdf, then decide under Terms whether whoever receives the file may print the document, copy text out of it, or edit it at all.

Redact a PDF for real: drag a black box over a name, and that page comes back as an image with the text underneath deleted.

Rotate PDF pages 90° or 180° and download a file that opens the right way up in every reader. Turn all of them or just a few.

Split a PDF by page range, pull out a single page, drop the ones you don't want, or burst one long file into a numbered set that downloads as a zip.

Remove the password from a PDF, or lift the owner restrictions that grey out printing and copying. Type the open password once and unlock a whole batch.

Add a watermark to a PDF: type CONFIDENTIAL or drop in a logo, place it on a grid of the page or drag it by hand, and see the real stamped page before you download.
