Are my files uploaded?

No. Edit & Sign PDF runs entirely in your browser using pdf-lib. Your PDF and your signature stay on your device — there is no server-side upload. You can verify in DevTools → Network: zero outbound bytes.

Is the signature flattened or editable?

It is flattened. Text and signature are written into each page's content stream, just like any other vector or image content, so the result looks the same in every PDF reader and cannot be peeled off afterwards.

Can I fill in interactive form fields?

This tool focuses on the much more common 'fill and sign' workflow: dropping freeform text and a hand-drawn signature on top of any PDF. It does not currently fill in AcroForm fields. If your form has live fields, type your text on top of them and the result will print correctly.

Will my signature look pixelated?

We crop the transparent margins off the canvas and embed the signature as a PNG. Place it at a comfortable size — about a third of the page width — and it will look crisp at print resolution.

Can I sign with a finger on mobile?

Yes. The signature canvas accepts mouse, trackpad, stylus, and touch input. Tap 'Draw signature', sign with your finger, then tap on the page to place it.

Which font does the text use?

Text is embedded using the standard PDF Helvetica font. That keeps the output file small and guarantees the text renders the same in every PDF reader.

Is there a file size limit?

There is no server-imposed limit because nothing is uploaded. The only practical limit is your device's available memory. Most laptops handle multi-hundred-page PDFs comfortably.

Can I stamp every page in one click?

Yes. After placing a signature, text field, date, or preset stamp, hover it and click 'All pages' (or use the 'Apply to all pages' toolbar button while it's selected). The annotation is duplicated onto every other page at the same coordinates and size, and each copy stays independently editable so you can tweak or delete it on a per-page basis. Like everything else in this tool, the duplication happens client-side — nothing is uploaded.

Which preset stamps are included?

Add stamp gives you Approved, Draft, Confidential, Reviewed, Paid, Void, Original, and Copy. They drop in as bold, uppercase, red text annotations that you can drag, resize, retype, or apply to every page. Custom stamp graphics aren't supported yet — for now the stamps are text-only so the output stays small and crisp at any size.

Is Edit & Sign PDF free to use?

Yes. Edit & Sign PDF is 100% free with no signup, no watermark, and no per-file or per-page limit. Converter.Plus is supported by ads, not subscriptions.

Fill and sign PDFs without uploading them

Most "edit PDF" tools online ask you to upload your contract or signed form to a server somewhere, edit it through their UI, then download the result. That's a privacy cost a lot of people would rather not pay — especially for offer letters, NDAs, leases, tax forms, and personal records.

Edit & Sign PDF takes the opposite approach. It loads pdf-lib in your browser, opens your PDF locally, lets you drop in text fields and a hand-drawn signature, and writes the changes straight into the file. The output is a brand new PDF, built on your device, that you download with a normal browser download. Nothing about your document leaves the tab.

Why "flattened on export" matters

A lot of PDF editors save text and signatures as annotations — overlays that some readers display and others ignore. That's fragile: a recipient can sometimes hide or remove your signature with a single click. Flattening writes those annotations directly into each page's content stream, so they look identical in every reader (Preview, Acrobat, Edge, Chrome, mobile) and cannot be silently dropped.

Sign with mouse, trackpad, or finger

The signature canvas accepts mouse, trackpad, stylus, and touch input. When you click Use signature, the transparent edges are trimmed automatically so the image scales tightly to the actual ink — not to the whole drawing area. You can place the same signature on as many pages as you like and resize it on each one.
