Sign PDF Documents Online — draw, type, or upload a signature — then place it exactly where you need it.
Process your PDF in your browser, place signatures or marks where you need them, and download a new copy without changing the original file.
The signing workspace
Upload a PDF, build an element, position it, then either stamp it everywhere or queue a different one per page.

A signature mark, placed precisely
Whether you draw it, type it, or upload it, this tool creates a signature mark and places it precisely on your PDF — on one page, on every page, or differently on each.
Draw it, type it, or bring your own
Some PDFs need a visible signature, date, or approval mark before they can be returned or shared. This tool lets you add that mark directly to the document without printing it first.
Whichever way you create it, the tool renders it to a PNG on a transparent canvas and lets you drag, resize, and rotate it directly on the page preview. pdf.js shows you the document; pdf-lib burns the final image into the exported PDF, at the position and size you choose.
Every element you can place
A drawn signature
This produces a freehand mark using your mouse, trackpad, or touchscreen.
A typed signature
Type your name once and pick from four script fonts — giving the typed name a handwritten-style appearance.
An uploaded signature
Bring a scanned PNG or JPEG — ideally with a transparent background — and scale it to fit.
Text and stamps
A date line, a name, or a preset like APPROVED or DRAFT — styled with its own color and size.
Independent placement per page
Queue a different element for each page instead of repeating one signature everywhere — see the deep-dive below.
Four steps from blank page to signed file
The same flow works whether you're signing once or building a different mark for every page.
Upload your PDF
Drag it onto the upload area, or click Select PDF. The document renders immediately — the PDF is processed locally in your browser rather than uploaded for signing.
Build and position an element
Use the right-side panel:
Choose how it applies
Pick Current, All, or Specific pages for one signature everywhere — or click Add to page to queue a different one per page, then repeat on other pages.
Finalize and download
Click Apply & Finalize. Review the signed PDF, rename it, and download.

Ways to add a signature or mark
Create a signature mark and place it precisely on your PDF — pick the method that fits your workflow.
Draw
Use a mouse, trackpad, or touchscreen to draw in real time. This produces a freehand mark using your input device in any chosen pen color.
Type
Type your full name and choose from four script fonts. This gives the typed name a handwritten-style appearance without requiring steady mouse control.
Upload
If you already have a scanned signature — ideally a transparent-background PNG — upload it directly and scale it to fit the signature line.
Text/Stamp mode
Switch the element type to add a date line or a preset stamp like APPROVED alongside your signature — styled independently in its own color and size.
Add a different signature or mark to each page
A 15-page document where each page needs its own initial, date, or approval mark doesn't need 15 separate uploads. Build the queue once.
Build a page's signature
On the page you're viewing, draw, type, or upload an element and position it exactly where it belongs.
Add it to the queue
Click Add to page — the element, its position, and that page number are saved as one queue entry, shown with a thumbnail.
Repeat, then finalize
Navigate to the next page, build a different signature, and add it too. Repeat for the pages you need. When you click Apply & Finalize, every queued page gets its own element — pages not in the queue are left blank unless you also use the bulk option.
PDF Signature Troubleshooting
Common placement, export, and signing issues, and how to resolve them.
Nothing appears on the page
No content has been created yet — the pad is empty, the type field is blank, or no image was uploaded.
Draw at least one stroke, type a name, or upload an image — the preview appears right after.
Signature landed in an unintended spot
The drag gesture finished at an unintended X/Y.
Enter exact X/Y values for precise placement.
One page's signature or mark is missing after finalizing
The queue was non-empty, but that page was never added to it — pages outside the queue stay blank when a queue exists.
Go back to that page, build and position an element, and click Add to page before finalizing again.
Same element ended up on every page instead of different ones
The queue was empty, so the bulk "Apply to Pages" setting (likely All pages) took over.
Use Add to page for each page you want to differ — a non-empty queue always overrides the bulk setting.
Typed name looks plain
A non-script font wasn't selected — the default sample may not have been clicked.
Choose a script font in the gallery to give the typed name a handwritten-style appearance.
A password-protected PDF won't open
Some password-protected or encrypted PDFs cannot be opened by in-browser engines.
Remove the password first with a PDF unlock tool, then upload the unlocked copy.
Signature or text looks faded in the output
The opacity slider is below 100%, or a light pen color was chosen.
Set opacity to 100% and pick a darker color to keep the signature clearer in the exported PDF.
Nothing appears on the page
Why: No content was created yet.
Fix: Draw, type, or upload something first.
Wrong spot
Why: Drag ended at an unintended coordinate.
Fix: Enter exact X/Y values for precise placement.
A page's signature is missing
Why: That page wasn't added to the queue.
Fix: Go back and click Add to page.
Same signature everywhere
Why: Queue was empty, bulk setting applied.
Fix: Use Add to page per page instead.
Typed signature looks plain
Why: A script font wasn't selected.
Fix: Choose a script font in the gallery to give the typed name a handwritten-style appearance.
Password-protected PDF won't open
Why: Some encrypted files cannot be opened in-browser.
Fix: Unlock it first, then upload.
Signature looks faded
Why: Opacity below 100% or light color.
Fix: Set opacity to 100%, use a darker color.
PDF Signing Best Practices
Simple ways to place signatures, dates, and stamps cleanly.
Keep the pen color black or navy
Dark colors usually provide better contrast in the exported PDF.
Add a date next to the signature
Switch to Text/Stamp and type "Signed on: DD-MM-YYYY" — Add a date when the document or recipient requires one.
Decide bulk vs. queue before you start
One signature everywhere is faster to set up; a different one per page needs the queue — know which you need before placing anything.
Review the queue list before finalizing
Each queued entry shows its page number and a thumbnail — scan the list to confirm every page you meant to sign is actually there.
Keep opacity at 100%
Full opacity keeps the signature clearer in the exported PDF.
Protect the file afterward
Once signed, run it through Protect PDF to add a password or editing restrictions to help protect the signed file.
Sign PDF — Frequently Asked Questions
If something's not covered here, the troubleshooting section above likely has it.
Is my PDF uploaded to a server?
The PDF is processed in your browser using pdf.js and pdf-lib. The file is not uploaded to AllInOneTools' server by this tool.
Are electronic signatures legally binding?
Electronic signatures can be legally recognized in many jurisdictions, including under frameworks such as the U.S. ESIGN Act and the EU eIDAS Regulation. Whether a particular signed PDF is legally sufficient depends on the document, signing method, and applicable jurisdiction. For documents with legal or regulatory requirements, verify the requirements with a qualified professional.
Can I put a different signature on every page?
Yes. Position an element on a page and click Add to page — it joins a queue. Move to the next page, build a different signature, stamp, or mark, and add that too. Apply & Finalize stamps each page with its own queued item.
What if I just want the same signature on every page?
Leave the queue empty, position your signature once, and choose Current page, All pages, or Specific pages under Apply to Pages — that one element gets stamped across your selections.
What's the difference between Draw, Type, and Upload?
Draw uses your mouse or touchscreen for a freehand signature. Type renders your name in a script font. Upload takes an existing signature image, ideally a transparent PNG.
What happens to my PDF after I finish?
The signed PDF is generated locally in your browser and downloaded as a new file. Your original PDF remains unchanged on your device.
Does this create a certificate-based digital signature?
No. This tool adds a visual signature, typed name, image, text, or stamp to the PDF. It does not create a certificate-based digital signature, signer identity verification, or an audit trail.
Are there PDF files this tool cannot process?
Some encrypted, password-protected, malformed, or unusually complex PDFs may not open correctly in the browser. If a PDF fails to load, try an unlocked copy or another PDF export.
Can I add stamps like APPROVED or CONFIDENTIAL?
Yes. Switch to Text/Stamp, click a preset (APPROVED, CONFIDENTIAL, DRAFT, PAID) or type your own, then place it like any other element — including queuing a different stamp per page.
The write-up on how this was built
Because drawing, placing, resizing, and exporting all run client-side, I wrote up the implementation — capturing canvas strokes as PNG, dragging an overlay element in sync with a rendered PDF page, and writing images into the final file with pdf-lib.
