Three steps. That's it.

No account creation. No file upload to servers. Just your PDF and your browser.

1

Drop your PDF

Drag and drop any PDF — fillable, scanned, or encrypted. It opens instantly in your browser.

2

Fill & annotate

Click anywhere to type. Add check marks, cross marks, strikeouts, or your signature. Move and resize everything.

3

Download or save

Download the finished PDF or save a .fillbuddy file to continue editing later. All annotations stay editable.

Everything you need. Nothing you don't.

One focused tool that does PDF filling brilliantly, instead of 30 tools that do it okay.

Truly private

Your PDF is processed with JavaScript in your browser. Zero bytes sent to any server. Disconnect your internet — it still works.

Click-to-place text

Click anywhere on the PDF to start typing. Adjust font size, move text around, edit anytime. No form field detection needed.

Check & cross marks

Place ✓ or ✗ marks of any size. Perfect for checkboxes, approval forms, and questionnaires.

Strikeout lines

Draw strikethrough lines across text. Resize width and thickness. Essential for redlining documents.

Signatures

Draw your signature or upload an image. White background is automatically removed for a clean, transparent result.

Save & resume

Save a .fillbuddy file to pick up exactly where you left off. Every annotation stays fully editable — no more "tattooed" text.

Sound familiar?

We built FillBuddy because every other option had the same problems.

"I saved my filled PDF and now I can't edit what I typed"

FillBuddy's save files keep all annotations editable. Come back anytime.

"This tool uploaded my tax form to a server I don't trust"

FillBuddy is 100% client-side. Your documents never leave your device.

"It doesn't recognize the form fields in my PDF"

FillBuddy doesn't need form fields. You type directly on the rendered page.

"I just need to fill one form, not pay $13/month"

FillBuddy is free. No hidden limits. No premium tier. No account.

"The free version puts a watermark on my downloaded PDF"

FillBuddy: no watermarks, no branding. Your PDF, clean.

Frequently asked questions

Is FillBuddy really free?
Yes — completely free with no hidden limits, no watermarks, and no account required. There is no premium tier.
Does FillBuddy upload my PDF to a server?
Never. Your PDF is processed entirely in your browser using JavaScript. No data is sent anywhere. You can verify this by disconnecting from the internet after loading the page — it still works.
Can I save my work and continue later?
Yes. Click "Save" to download a .fillbuddy file that preserves your PDF and all annotations. Upload it again anytime to continue editing — all previous work remains fully editable.
Does it work with non-fillable or scanned PDFs?
Yes. FillBuddy renders your PDF visually and lets you place text, marks, and signatures directly on top. It doesn't depend on embedded form fields, so it works on any PDF.
What tools are available?
Text placement (with adjustable font size), check marks (✓), cross marks (✗), strikeout lines, and signatures (draw or upload with automatic background removal). All elements are movable and resizable.
How is FillBuddy different from Smallpdf, iLovePDF, or Adobe?
Those tools upload your documents to their servers for processing. FillBuddy is 100% client-side — your files never leave your device. Plus, our save/resume feature lets you re-edit filled PDFs, while others permanently bake annotations in.
