PDF Form Filler

Last updated: April 2026

Fill PDF form fields, checkboxes, dropdowns, and signature areas online so you can complete and export forms without switching to desktop software.

Privacy-first: No signups, no long-term storage, and uploaded PDFs are deleted automatically after the download is prepared.
1

Upload your PDF

Max 25MB. Fillable AcroForm PDFs work best.

No PDF selected yet.

Scanned or flattened PDFs can still be signed, but their fields cannot be auto-filled.

2

Review detected form fields

Upload a PDF first and the tool will inspect it for AcroForm text fields, checkboxes, and dropdowns.
3

Create and place your signature and initials

Edit one mark at a time. Signature and initials keep separate sources, pages, placement, and appearance, then download together in one flattened PDF.

Use mouse, trackpad, or touch. You can also upload a PNG, JPG, or WebP signature image.

The active mark is currently set to the preview page only.

Page size

Waiting for a PDF.

Nudge placement

. . . .

Base placement is active for the current page.

Position values use the PDF page's top-left corner. Uploaded or drawn signatures are trimmed before placement so the preview and final PDF line up more closely.

Download your result

Filled and signed output is flattened before download so form fields are no longer easily editable.

Protect PDF Add password protection to a PDF so the file is harder to open without approval, while keeping the workflow simple for common sharing tasks. Compress PDF Online Compress PDF files online for email, WhatsApp, and uploads. Choose a compression level, reduce file size fast, and download a smaller file in minutes. Merge PDFs Online Combine multiple PDFs into one file in seconds, then download a single document that is easier to send, store, print, or submit without extra steps.

This tool fills AcroForm PDF forms - the most common type of interactive PDF used for government applications, tax forms, HR documents, lease agreements, and standard business paperwork. Upload a fillable PDF and the tool automatically detects all text fields, checkboxes, and dropdowns so you can complete them without printing.

After filling the form fields, you can draw, type, or upload a signature and place it precisely on the document. Signature and initials are kept separate so you can apply each to different pages or positions. The final output is a flattened PDF - all filled content is baked into the document so fields cannot be edited after download.

If the PDF you upload does not have interactive AcroForm fields - because it was scanned, or the fields were flattened by a previous tool - the field detection step will show no fields. In this case, you can still add and place a signature on the document using the signature panel.

This workflow is designed for straightforward form completion. It works best with modern AcroForm PDFs created in Adobe Acrobat or similar tools. PDFs with XFA forms (an older Adobe standard used in some government and tax forms) may not be supported - XFA forms typically open best in Adobe Acrobat Reader itself.

What to Expect

Detect fillable AcroForm fields, complete them online, and add a signature to produce a flattened PDF ready for submission or sharing.

AcroForm vs scanned PDF - what's the difference?

An AcroForm PDF has interactive fields built into the file structure. When you click on a field in a PDF reader, a text cursor appears - this is an AcroForm field. A scanned PDF is a photograph of a paper document with no interactive fields. The form filler works with AcroForm PDFs. For scanned forms, you can still add a signature, but you cannot auto-fill the fields.

Is the output legally valid as a signed document?

A drawn or typed e-signature placed with this tool creates a signed PDF that is widely accepted for everyday business documents. For contracts with specific legal requirements in your jurisdiction, check whether a qualified or advanced electronic signature standard is required.

Frequently Asked Questions

What PDFs work with the PDF Form Filler?

Fillable AcroForm PDFs work best. Scanned, flattened, or print-only PDFs do not expose editable form fields for automatic detection or filling.

Can I detect fields automatically?

Yes. Upload a PDF and the tool lists detected text fields, checkboxes, and dropdown fields with their current values.

Will the completed PDF still be editable?

No. Filled and signed output is flattened before download so the visible content stays in place and form fields cannot be edited easily afterward.

Can I add an e-signature, initials, or stamp the same mark on more than one page?

Yes. You can draw or upload a signature or initials image, choose one page or selected pages, set the placement, and download the flattened PDF.

What is the PDF size limit?

Up to 25MB per PDF.

Are uploaded PDFs stored after processing?

No. PDFs are processed temporarily to generate your download, then deleted automatically. No signup is required.
