Sign PDF Online — Add Your Signature to a PDF Free

Upload the PDF, type a stylised signature, draw one with your mouse or finger, or upload a transparent PNG of your scanned signature. Tap the page to place it, drag to fine-tune, add your initials with the Text tab, then download a signed PDF that opens cleanly in every reader.

In most jurisdictions yes — the US ESIGN Act, EU eIDAS, UK Electronic Communications Act and India IT Act all recognise simple electronic signatures for routine contracts (employment offers, NDAs, freelance agreements, invoices). High-value transactions may require qualified e-signatures.

Yes. Place a signature where each party signs, download the partially-signed PDF, send it to the next signer and have them open it here to add theirs. The tool stamps visible signatures only; it does not create signature fields or record who signed when.

Place a signature from the Signature tab, type your initials in the Text tab and add a date from the Date tab, then tap any page to drop each one. The date uses today's date by default but you can pick another. Everything is stamped into the page when you download.

Page previews render locally, but signing itself happens on our secure server: your document and signature image are uploaded over HTTPS, retained temporarily to stamp and deliver the PDF, then removed under our Security policy. We never sell them or use them to train models. That works well for everyday paperwork like employment contracts and NDAs; if your policy requires a signer that never uploads the file at all, use an offline desktop PDF tool instead.

This tool has no lock option. Signatures, initials and dates are stamped into the page when you download, but a PDF editor can still change the file. To add a password, run the signed PDF through PDF Password afterwards.

This tool adds an electronic signature — a visible image of your drawn, typed or uploaded signature stamped onto the page — which is legally valid for everyday agreements like NDAs, offers and invoices. It does not create a certificate-based digital signature (the cryptographic kind Acrobat verifies against a .p12 / PKI certificate). For routine documents an electronic signature is what you need; for paperwork that must be cryptographically tamper-verifiable, use a certificate-based signing service.

This tool focuses on signatures, initials, dates and stamps that you place anywhere on the page. If your PDF has interactive form fields — checkboxes, text inputs, dropdowns — to complete, use our Fill PDF Form tool to fill them first, then return here to add your signature.

Yes — switch to the Text tab and type your paragraph, then pick a font family (Sans, Serif, Mono or Handwritten), a text color, and drag the size slider to set how large it renders on the page. Bold and italic toggle buttons next to the size slider let you emphasize the text without leaving the tool.

In the Signature tab, choose the Type mode, enter your name, then pick from eight cursive font styles — Caveat, Dancing Script, Great Vibes, Sacramento, Allura, Pacifico, Homemade Apple or Kalam — shown as live previews of your own name. Each renders a different handwriting look, so you can match the tone of the document you're signing.

Open the Date tab, pick a day with the date field or tap Today for the current date, then choose a format from the dropdown — MM/DD/YYYY, DD/MM/YYYY, YYYY-MM-DD, Month DD, YYYY, or DD Month YYYY. The live preview under the format picker shows exactly how the stamped date will look before you place it, and you can still adjust its font, color and size like the text tool.

Yes — in the Stamp tab, choose Create mode and enter your company name plus a short line like APPROVED, PAID or DRAFT; the tool generates a circular stamp graphic in the color you pick with the color field. If you already have a real company stamp image, switch to Upload mode instead and use that PNG or JPG directly.

Use the Signature tab (Type mode with a cursive font, or Draw if you prefer your real signature) to place your name, then switch to the Date tab and pick a format like Month DD, YYYY with Today selected for a professional-looking date stamp. Finally, add a Stamp in Create mode reading APPROVED in your brand color to mark the document reviewed — all three can be dragged and resized independently on the same page before you download.

In the Signature tab, choose Draw mode and sign directly on the canvas with your mouse, trackpad or a finger/stylus on touchscreens. If it doesn't come out right, tap Clear underneath the canvas to wipe it and try again — the tool automatically trims the transparent border around your ink so the signature drops onto the page at the right size.

Drag anywhere on a placed item to move it, or drag the small handle at its corner to resize it — text and date items automatically scale their font size as you resize. On a touchscreen you can also pinch with two fingers to resize and reposition in one gesture, and pressing Delete or Backspace removes whichever item is currently selected.

Yes. Use the Prev/Next arrows or the page thumbnail strip to jump between pages — each thumbnail shows a small badge with how many items you've already placed on it. The Placed signatures list in the Pages panel lets you tap any item to jump straight back to its page and select it, or delete it from there.

Once your PDF finishes rendering, a one-time popup asks for your full name (pre-filled if you're signed in) and, when you confirm, instantly builds a typed cursive signature from it and switches you to the Signature tool so you can tap the page to place it immediately. Tap Skip if you'd rather draw your signature or upload an image instead.

Switch to the Stamp tab, then either use Create mode to type your company name and a short line of text like APPROVED, PAID or DRAFT and pick a color — the tool renders it as a circular stamp graphic on the spot — or switch to Upload mode to drop in an existing PNG or JPEG of your company's real rubber stamp. Once it's rendered or uploaded, tap Add to page (or tap anywhere on the document) to place it just like a signature.

Yes — the Text tab is separate from Signature, Date and Stamp and lets you type a full paragraph (for example a certification statement or a note to the recipient) into a textarea. You can pick one of four fonts (Sans, Serif, Mono or Handwritten), set a color with the color picker, adjust size with the 1-6% slider, and toggle Bold or Italic before placing it on the page.

Yes — Pixoate supports batch and bulk processing. Switch to Batch mode, add up to 60 PDFs on Premium or 200 on Pro, set your options once, and every PDF is processed with the same settings before you download a single ZIP. Bulk processing is a Premium feature; the output uses the same quality and settings as single mode.

Yes — with bulk processing you configure the settings a single time and they apply to every item in the batch — up to 60 PDFs on Premium or 200 on Pro. There is no need to repeat the setup per item, and Temporary uploaded and generated files are processed securely and deleted automatically.

Almost always one of three things. The file is over the 20 MB free upload limit — Premium takes 50 MB and Pro 120 MB. The format is not one this tool accepts, so check the list shown on the upload panel. Or the file is not really the format its name says: renaming a file does not change what is inside it, and that is the reason a valid-looking PDF gets refused.

Page content is preserved, but anything that depended on the original file being interactive can behave differently — form fields, layers and annotations may be flattened into the page depending on the operation you ran. If you need the fields to stay fillable, do the flattening step last. Keep the untouched original until you have checked the output end to end.

Sign PDF supports free standard use within the published processing allowances. Free downloads are clean — no watermark. No signup is required for standard tool use. Photo effects and AI edits have a web-size limit on Free, with the original-resolution result available through Premium or one credit. Crop, resize, rotate, compress and convert stay full size. Premium supports batches of up to 60 files, with the applicable plan limits shown before processing.

No — Sign PDF runs in the browser on desktop and phone. There is nothing to install, no trial to start, and no license to buy before you can see whether it does what you need. Try it on the file you are actually stuck with rather than a sample.

Sign PDF cannot insert a signature into a Word file, because it works on PDFs only. Turn the document into a PDF with Word to PDF, place your signature on that PDF here and send the signed copy. If the signature has to stay inside Word, make a transparent PNG with Signature Generator, which you can use in Word.

Batch signing is a Premium feature. Place the signature, date, text or stamp once, add several PDFs and the same positions are applied to each file, delivered together as one ZIP. For a single document, the standard signing flow needs no batch mode.

Sign PDF cannot open a PDF that asks for a password, so remove the password first with Unlock PDF, which needs the password you already know. Then sign the unlocked copy. If the signed file should be locked again, add a password with PDF Password afterwards.

Sign PDF is not a signature request service: it does not email documents, send reminders or track who has signed. You sign your own copy here. For a second signer, send them the signed PDF and ask them to add their signature with this tool in turn, then return the finished file to you.

Sign PDF places a visible signature, not an interactive signature field, so it does not create a clickable box. For a signature line, type a label such as Signature: and an underline with the Text tab and place your signature beside it. The line is part of the page and cannot be clicked to sign.

An esignature is an electronic mark, such as a drawn, typed or image signature, that shows you agree to a document. Sign PDF adds that kind of visible signature to a page. It does not verify the signer or add a certificate, and acceptance depends on the document and the rules that apply to it.

Upload the PDF, create your signature with Draw, Type or Upload in the Signature tab, then tap the page to place it and drag it onto the signature line. Select Sign my PDF and download the signed copy. Nothing needs to be printed or scanned.

Sign PDF adds a visible electronic signature and does not add a certificate. If a recipient requires a certificate-based digital signature, you need software that issues and verifies digital IDs. For paperwork that only needs your visible signature, place it here.

Yes. Adding a drawn, typed or uploaded signature to one PDF is free, and the signed copy carries no watermark. Signing many PDFs at once with the same placement, which returns one ZIP, is a Premium batch feature.

Open Sign PDF in your browser, upload the PDF, create a signature and place it. No Adobe account or desktop program is involved, and it works in any current browser, including on a phone. Download the signed copy when it is ready.

A paper page has to become a PDF first. Photograph or scan it with Scan to PDF, or turn pictures into a PDF with Image to PDF, then upload that PDF here and place your signature. The signed copy downloads as a PDF you can send without printing.

Word has its own digital signature feature, which may require a digital ID, and Sign PDF does not replace it. This tool cannot add a digital signature to Word files or create a certificate. For a visible signature, make a transparent PNG with Signature Generator and place it in Word, or sign a PDF copy of the document here.
