Visual electronic signatures, fully local
On-device processing opens pages, renders previews, adds transparent image objects, saves, and reopens the result on this device. Your original is never overwritten or sent to a server.
Private visual PDF signing
Add your signature to a PDF without uploading it.
Add a visual electronic signature to a PDF while the document and signature image stay in your browser. Draw, type, or upload a signature, remove its background if needed, preview placement, move or resize it across pages, then download the signed-looking PDF. This is not certificate-backed cryptographic signing, does not prove identity or consent, and editing can invalidate existing signatures.
Not certificate-backed, cryptographic, or PAdES signing
This focused tool places visible marks. It does not prove identity, create a digital signature field, use a private key, or provide a legal-validity guarantee. Visible edits can invalidate an existing digital signature.
How to sign a PDF visually
Create once, preview clearly, place exactly.
1
Draw, type, or upload
Choose pen color and width, a script font, or a photographed signature.
2
Clean and preview
Adjust ink sensitivity to remove pale image backgrounds, then review transparency.
3
Place across pages
Move, proportionally resize, duplicate, delete, navigate, zoom, and undo.
4
Validate and download
Reopen the output and verify page count, geometry, rotations, and added objects.
Reusable, removable local signatures
Save a transparent signature in this browser for later documents, reuse it offline, and delete it explicitly at any time.
Mouse, touch, stylus, and keyboard
Pointer-based drawing and placement support common input devices. Selected marks can also be nudged or deleted from the keyboard.
Mixed pages stay coordinate-correct
Placements use visible page coordinates that map through each visible page area and rotation, preserving portrait, landscape, and mixed page geometry.
Frequently asked questions
Know what the signature does before you download.
Does PdfEditorOnlineFree upload my PDF or signature?
No. The PDF, drawing, typed signature, uploaded image, background cleanup, saved signature library, output, and validation remain in your browser.
Is this a cryptographic digital or PAdES signature?
No. This tool adds visible electronic signature marks. It does not verify identity, use a signing certificate or private key, add a trusted timestamp, or create a PAdES signature.
Where are saved signatures stored?
Only in this browser's local storage. Each saved signature has an explicit delete control. PdfEditorOnlineFree never stores the source PDF in the signature library.
Can signing affect an existing digital signature?
Yes. Adding visible page content changes the PDF and may invalidate existing cryptographic signatures. Review the downloaded copy in the viewer required for your workflow.
Prepare pages before signing
Correct page orientation or geometry first. After signing, flatten or certificate-based workflows may have different requirements.
