Everything you can do
Everything you need, one editor, nothing to install.
Upload a PDFMultiple PDFs in tabs
Open several files at once and switch between them like browser tabs — no reloading, no losing your place.
Add shapes
Draw lines, arrows, rectangles and circles straight onto the page. Move or resize anything afterwards.
Add symbols
Drop tick marks, crosses and stars into checkboxes. A live preview follows your cursor so it lands centred.
Add images
Place a signature, stamp or logo anywhere on the page, then drag and resize it into position.
Page arrangement
Add blank pages, delete the ones you don't need, or drag thumbnails to reorder the whole document.
Export a single page
Pull one page out as its own PDF — with all your markup on it — without splitting the whole file.
Merge PDFs
Combine every open file into one document, in the order you arranged the tabs.
Link & sync text
Type a value once in the toolbox and every linked box on the PDF updates instantly — ideal for forms where the same detail repeats.
Copy & paste anything
Select a stamp, signature, text or shape — right-click and drag to grab several at once — press Ctrl+C, then Ctrl+V on any page, even in a different PDF. It lands in exactly the same spot.

Draw/highlight, add text, add images, add symbols (ticks, crosses, stars), shapes (lines, arrows, rectangles, circles), page management, and Link & Sync Text for forms where the same value repeats.
Type a value once (like a name or date) and place it in multiple spots on your PDF. Edit it once, and every linked spot updates automatically — great for repetitive forms.
Yes — open the PDFs you want to combine as tabs, arrange them in the order you want, then use Merge PDFs. They'll download as one combined file.
Yes. Open Page management, right-click (or tap the menu on) any page, and choose Export Page — it downloads as its own standalone PDF.
Editing happens entirely in your browser. Nothing is uploaded anywhere unless you're logged in and choose to click Save Project — only then is it stored on your account.
