Place a signature and fill PDF form fields

PDF Sign places your signature on a PDF and fills AcroForm fields when the document defines them. You can draw with a pointer, type a stylized name, or upload a PNG of your ink. The signed file is assembled in the browser; the unsigned original on disk stays untouched unless you overwrite it yourself.

This is a practical path when a landlord sends a fillable lease, a clinic emails a consent PDF, or a volunteer form expects checkboxes plus a signature line. It is not a certified qualified signature with a government-issued token. Treat output like a printed-and-scanned signature: convincing for many workflows, insufficient where regulations demand PKI.

1. Open PDF Sign and drop the PDF. Remove third-party passwords in a reader if opening fails.
2. Walk the fields. Text boxes, dates, and checkboxes wired as AcroForm fields accept focus taps. If a label is only a line with no field, place the signature image on the line manually.
3. Choose draw, type, or upload for the signature. Resize and drag until the ink aligns with the printed label.
4. Download and open every page. Print one page as a test if the recipient will print.

Signing means you stand behind the content. Read the full PDF before you ink, including attachments referenced but not embedded. Do not sign blank forms expecting someone else to complete them later unless your process explicitly allows countersignature.

Visual signatures are forgeable if someone steals your PNG. Prefer drawing on a device only you control. Store signature images outside shared cloud folders.

Multi-page packets may need a cover memo signed separately, then combined. Build the packet using PDF Merge after each signed piece is verified, following the checklist in assembling a PDF application packet. Put signature pages on the pages the checklist names; reorder is a separate step if scans arrived upside down.

When a portal wants a photo ID beside the form, prepare the portrait with ID Photo and keep identity images out of casual email threads.

Scanned PDFs sometimes look like forms but contain no fields. Sign on the line anyway. Use a consistent scale so your ink does not dwarf the printed text. For repeated initials on every page, duplicate the signature placement rather than stretching one image across the file.

If checkboxes are pictures, you cannot toggle them; mark with an “X” using draw mode or print and ink physically when the authority requires wet signatures.

QuickConvert does not upload the PDF or signature. Processing stays in the tab as with PDF Watermark. Analytics may record a visit; it does not receive document bytes, as explained in privacy with online file tools.

Some portals flatten fields on upload. Keep the editable download until you confirm acceptance. If a viewer warns that signatures are broken, flatten in a desktop reader after review.

Do not sign on behalf of someone else using their PNG unless your role explicitly allows proxy signature and local law permits it. For minors, parents sign the parent line, not the child’s name in cursive.

Touchscreens work for draw mode; use landscape when the pad feels narrow. Zoom the PDF preview before placing small initials. If your pointer is shaky, type mode plus a careful placement often looks cleaner than a rushed finger line.
