Does PDFWix support digital (cryptographic) signatures?

No — only simple electronic signatures (typed, drawn or uploaded image). These satisfy the US ESIGN Act and EU eIDAS simple-signature requirements. For certificate-backed digital signatures use Adobe Acrobat.

How to Fill a PDF Form on Android

Q: What if the PDF has no real form fields?

It's a flat PDF — common for scanned tax forms and government applications. PDFWix lets you place text boxes, checkmarks, dates and a signature anywhere on the page, then flatten the result so the values are baked in and can't be edited later.

How to Fill a PDF Form on Android

Fill a PDF form on Android in Chrome with PDFWix — AcroForm fields supported. Free, browser-based, no app install, no signup, no watermark on output today.

Why filling PDF forms on Android is annoying

PDF forms come in two flavours: real AcroForm fields (the kind you can tab between) and flat PDFs (typed-or-scanned forms with no interactive layer). Most Android tools handle one but not the other, and many gate the second flavour behind a subscription.

Native Android method (and its limits)

Google Drive's PDF viewer cannot fill forms. Adobe Acrobat Reader is the de facto choice — free for AcroForm fields, but the 'fill scan' feature for flat PDFs is gated behind the $9.99/month Premium subscription.

Fill a PDF form on Android with PDFWix

Open pdfwix.com/fill-pdf-form in any browser on your Android device. Drag in your PDF. PDFWix auto-detects AcroForm fields and lets you tab between them. For flat PDFs, click anywhere on the page to add a text box, checkmark, date or signature. When you're done, click Download — your filled PDF saves to your device with the values flattened in so they print and view correctly everywhere.

Everything runs in your browser. No upload, no signup, no per-form fee. Works on AcroForm and flat PDFs in the same workflow.

When the native method is fine

Use the built-in tool for one-off forms with proper AcroForm fields. Use PDFWix when the form is flat (scanned/government), when you need a signature, or when you want the same workflow on every device.

How it works

Open the form filler — Open pdfwix.com/fill-pdf-form in Chrome or Samsung Internet on your Android.
Add the PDF — Drag the form PDF onto the dropzone.
Fill the fields — Tab through AcroForm fields, or click anywhere to drop text/checks/signatures on flat PDFs.
Download flattened — Click Download — the filled, flattened PDF saves to the Downloads folder (visible in Files by Google).

Frequently asked questions

Can I fill a PDF form on Android for free?

Yes. PDFWix's Fill PDF Form tool runs in any browser at no cost — no daily cap, no signup, no watermark on the saved file. Adobe Acrobat Reader also fills AcroForm fields free, but charges $19.99/month for advanced field editing.

What if the PDF doesn't have real form fields?

It's a 'flat' PDF — common for scanned tax forms and government applications. PDFWix lets you place text boxes, checkmarks, dates and a signature anywhere on the page, then flatten the result so the values are baked into the PDF and can't be edited later.

Are filled-in values searchable and selectable?

Yes. Filled text becomes real PDF text (not an image), so it can be selected, copied, OCR-indexed and searched in any reader.

Will the form print correctly?

Yes. PDFWix flattens form values into the page on download, so every field prints exactly as it appears on screen — no missing checkmarks, no blank text fields.

Is my filled PDF uploaded to your servers?

No. Form filling runs entirely in your browser via WebAssembly. The PDF and every value you type stay on your device.
