Signer PDF en ligne

What Signer PDF does

Signer PDF adds a handwritten-style signature to a PDF. You draw it with a mouse, finger or stylus, or type your name and have it set in a cursive font. Then you place it on the page, resize it, and add the date or other text such as your printed name.

The signature is saved as a PNG image with a transparent background and drawn onto the page with pdf-lib, together with any text you add. The result is saved as a new file with -signed at the end of the name. This is a visual electronic signature, not a certificate-based digital signature.

Comment utiliser Signer PDF

1. Déposez le PDF sur lequel vous voulez travailler.
2. Choisissez un outil dans la barre d'outils, puis cliquez sur la page pour l'utiliser.
3. Déplacez, redimensionnez ou supprimez vos ajouts avant d'enregistrer.
4. Cliquez sur Enregistrer le PDF pour télécharger le résultat.

When to use Signer PDF

• Sign a rental agreement, freelance contract or NDA that was sent to you as a PDF, without printing and scanning it.
• Add your signature and the date to a school permission slip, consent form or medical questionnaire.
• Sign delivery notes, timesheets or expense reports and send them back to a manager or client by email.
• Initial each page of a long agreement by drawing short initials and placing them in the page margins.

Settings explained

Signature

Opens the signature pad. Choose Draw or Type, pick the ink color, and click Use signature. Then click on the page where it should go and drag the corner handle to resize it; the proportions stay fixed.

Draw

Sign in the box with a mouse, touchpad, finger or stylus. A finger or stylus on a phone or tablet usually gives the most natural result. If you make a mistake, click Cancel and open the pad again.

Type

Type your name and it is shown in a cursive script font installed on your device, such as Brush Script MT or Segoe Script. The style can look different on different computers and phones.

Date

Click on the page to insert today's date in the date format of your browser's language. The date is a normal text box, so you can click into it and change the date or its format.

Text

Adds your printed name, job title, place of signing or any other text next to the signature. The Color and Font size settings in the toolbar apply to the new text.

Qu'est-ce que le format PDF ?

PDF (Portable Document Format) est un format de document créé par Adobe en 1993. Les fichiers portent l'extension .pdf.

PDF was created by Adobe to show documents the same way on any device and printer. A PDF file describes pages with text, fonts, vector graphics and images at fixed positions. It became an open ISO standard in 2008, and there are special variants such as PDF/A for archiving and PDF/X for printing.

PDF is the right choice for documents that must look the same everywhere, such as contracts, invoices, forms, manuals, reports and files for printing. It also supports digital signatures, fillable forms, comments and password protection.

PDF is hard to edit, because text is stored as positioned pieces, not as flowing paragraphs. Converting a PDF to Word may change the layout. Scanned PDFs contain pictures of text, not real text, unless OCR has been applied.

All major web browsers open PDF files directly. Windows, macOS, iOS and most Android phones include a PDF viewer, and Adobe Acrobat Reader and many free apps can view, annotate and fill PDF forms on all platforms.

Pourquoi utiliser l'outil Signer PDF de FansBond

La plupart des convertisseurs en ligne envoient vos fichiers sur leurs serveurs. L'outil Signer PDF de FansBond fait tout le travail dans votre navigateur, grâce à WebAssembly et aux API modernes des navigateurs. Vos fichiers restent sur votre appareil, ce qui est plus sûr pour vos photos privées, vos contrats et vos projets non publiés, et c'est souvent plus rapide puisqu'il n'y a rien à envoyer ni à télécharger.

Pas de file d'attente, pas de filigrane, pas de compte. Une fois la page chargée, l'outil continue de fonctionner même avec une connexion lente.

Tips for the best result

• Each signature you create is placed once. To sign several pages, click Signature again and create the signature for each page you need.
• Use most of the pad when you draw. The whole pad area is saved, so a small signature leaves empty space around it and looks tiny on the page.
• Dark blue or black ink looks most like a real pen signature and stays readable when the document is printed or scanned again.
• Check the result in a PDF viewer before you send it. After saving, the signature, date and text are part of the page and cannot be moved.

How Signer PDF works in your browser

Each page is rendered with pdf.js so you can see it and place items exactly. What you add is kept as separate objects until you save, so you can move, resize or delete it at any time.

When you save, pdf-lib writes your text, drawings, images and fields into the original PDF. The original page content is not re-rendered, so existing text stays sharp and selectable.

Privacy and security

Most online converters upload your files to a server, process them there and keep a copy for some time. Signer PDF works differently: the code is downloaded to your browser once, and your files are read and written only on your device.

You can check this yourself: after the page has loaded, turn off your internet connection and the tool still works. This makes it safe for contracts, IDs, medical records, private photos and unreleased work.
