How to edit, sign and fill in a PDF for free

You don't need expensive software to fill in a form, add a note or sign a letter. These tools change what's on the page, and your document never leaves your device.

Edit PDF: add text, pictures and drawings

Edit PDF adds text, pictures, shapes and freehand drawings. Choose Select to move, resize, recolour or delete anything you added, and double-click text to retype it.

Changing text that's already in the PDF? Cover it with a white filled rectangle and type the new text on top. For bigger changes, convert with PDF to Word, edit in Word and convert back with Word to PDF.

Sign a PDF

Sign PDF lets you draw, type or upload your signature and place it on the page. Add your name or the date with Text. This is a simple electronic signature, accepted for many everyday documents; some contracts require a certified digital signature from an identity provider. Your signature isn't stored: it's gone when you close the page.

Fill in or create PDF forms

PDF Forms fills in existing forms, and turns any PDF into a fillable one. Add text fields, checkboxes and dropdowns yourself, or let GrovePDF find the blanks: lines of underscores, empty boxes and labels ending in a colon. The fields are standard PDF fields that work in any reader. Before sending, Flatten turns the answers into normal page content so they can't be changed.

Watermark, logo and stamps

  • Watermark stamps text such as DRAFT or CONFIDENTIAL, or your logo, on chosen pages, at any angle, size and transparency, or repeated across the page.
  • Add image to PDF places a logo, stamp, photo or signature exactly where you drag it, on one page or every page. PNG files with a transparent background look best.

Page numbers

Page numbers adds numbers where you want them, in the style you choose: 1, Page 1, 1 / 12 or Page 1 of 12. Tick Skip the first page to leave the cover unnumbered, or set Start at to continue from another document.

Crop margins

Crop PDF trims white margins or keeps just part of a page, on every page or only the one shown. Cropping hides the rest of the page rather than deleting it, so don't use it to remove private information: use Redact PDF for that.

Change the page size

Resize PDF puts every page on one paper size (A4, Letter, Legal, A3 or A5), scaled to fit and centred. Use it when a PDF mixes page sizes, or when an upload form or printer expects A4. Text stays sharp and selectable; nothing is cut off.
