Fill PDF Without Adobe

You don't need Adobe Acrobat or Acrobat Reader. Every step — rendering, filling, signing, saving — happens in your browser using open-source JavaScript.

That means your file never leaves your device. No upload. No server copy.

Fill PDF on Your Phone

FillPDF.app is built mobile-first with its own in-browser keyboard, so typing works the same on every device.

• Number pad and email layout built in
• Arrow pad for precise positioning
• Sign with your fingertip

Select, Move & Edit — Tap Once vs. Tap Twice

The Select tool is how you move, edit, resize or delete anything you've placed on the page. It uses two gestures:

• Tap once — the item becomes selected (a blue dashed outline appears). While selected, drag it to move it, or use the arrow pad (◀ ▲ ▼ ▶) that appears in the options bar to nudge it pixel by pixel. Press Delete to remove it.
• Tap twice (double-tap) — the text editor and keyboard reopen with that item's existing content, so you can edit it. This only applies to text, number and email boxes.

So the pattern is: tap once to grab it, tap twice to type in it. Nothing happens to text unless you intentionally tap it twice, which means you'll never accidentally overwrite a filled-in field while repositioning it.

Three Keyboards: Text, Number and Email

FillPDF.app shows you exactly the keys you need for the field you're filling — no switching between layers just to type an @ or a digit.

• Text — a full QWERTY keyboard for names, addresses, and any general-purpose text.
• Number — opens directly on a digits layout (1–9, 0) with -, /, :, ., , and + ready. Perfect for phone numbers, ZIP codes, IDs and amounts.
• Email — a letter keyboard with @ and . permanently visible, so typing an email address is a single row of keys instead of constant layer switching.

Each keyboard has a Tab key that jumps to the next empty field on the page, so filling a multi-field form is just type → Tab → type → Tab.

Move with Arrow Buttons

Not every device drags cleanly — so every selected item also has a directional pad in the options bar: ◀ ▲ ▼ ▶. Tap an arrow to move the selected item 5 pixels in that direction.

• Works for text, checkmarks, dates, signatures, highlights, shapes, arrows, freehand drawings and images.
• Perfect for fine-tuning placement when a drag overshoots.
• On desktop, you can also use the physical arrow keys on your keyboard, and hold Shift to jump 10 pixels at a time.

So if drag doesn't work on your device for whatever reason, the arrow pad always does — it's a guaranteed way to reposition anything you've placed.
