Sign from the phone you already have
A contract arrives on WhatsApp, a landlord emails a rental form, a school sends a permission slip. On Android you can sign all of them without a printer, a scanner or a laptop. PDFbat runs in Chrome, Samsung Internet and other modern browsers, so there is nothing to download and your phone storage is untouched.
Open Fill and Sign, pick the PDF from your phone, Google Drive or downloads, tap Sign and draw your signature with your finger or an S Pen. Place it on the line, resize it, add the date and initials, and download. If the form has real fields, you type straight into them. If it is flat, you tap and type where the answers go.
When more than one person needs to sign, use Send for signature instead. Add each signer, drop a signature field where it belongs and PDFbat emails them a link. They sign on their own phone in the browser. You get a sealed PDF with an audit trail when everyone is done.

Tips for signing on a phone screen
- Turn the phone to landscape for wide forms and pinch to zoom before placing a signature.
- Draw slowly and large, then shrink the signature to fit. A bigger drawing looks smoother when resized down.
- If the PDF came as a photo of paper, run OCR or use Add text for answers on the printed lines.
- Keep Save for next time on so you do not redraw your signature on every form.
Fill and Sign or Send for signature
Use Fill and Sign when only you need to sign. It is instant and the free plan covers it. Use Send for signature when other people must sign too. The free plan allows 3 envelopes a month and Pro at $4 a month removes that limit. Signers never need an account, and the final PDF is digitally sealed with a certificate of completion.
