pdfFiller alternatives: free and one-time-price options (2026)

pdfFiller is a capable cloud PDF editor, but it's a subscription and your document is uploaded to its servers. If you fill, sign or tweak PDFs now and then, you can probably do it for free, on your own computer. Here's how to pick.

Short answer. To fill and sign: use the free tools you already have (Chrome or Edge, Mac Preview, Acrobat Reader) or a local extension like Penwise. To rewrite existing text: LibreOffice Draw (free, rough) or Acrobat Pro (paid). To collect signatures from other people: a dedicated e-signature service, which is a different kind of product from a PDF editor.

Why people look for a pdfFiller alternative

None of that makes pdfFiller bad. If you need cloud storage, templates and team workflows in one place, it can be the right fit. This guide is for people who just want the PDF filled in.

The alternatives

1. Your browser's built-in PDF viewer (Chrome, Edge)

Open the PDF in the browser, click into a field and type. Edge also has "Add text" and "Draw" for flat PDFs. Good for: fillable forms, quick notes. Limits: no saved signature, little control over flat PDFs in Chrome.

2. Mac Preview

Preview fills forms, adds text and stores a signature you can reuse. Good for: Mac users. Limits: Mac only; fiddly on complicated forms.

3. Adobe Acrobat Reader (free)

The Fill & Sign tool handles forms and signatures well. Good for: complex forms. Limits: a big install with regular prompts for paid features.

4. Penwise (Chrome extension)

Disclosure: we make Penwise.

Fills form fields, adds text anywhere, and signs by drawing, typing or uploading, with saved signatures. Files are processed in your browser and never uploaded. Filling, signing and downloading are free with no watermark; redaction and page tools are in Pro, a one-time $9.99. Limits: Chrome and Chromium browsers only, it doesn't edit existing text, and non-Latin text is saved as an image rather than real text.

5. LibreOffice Draw

Free and open source, and one of the few free tools that lets you edit existing PDF text. Good for: small text fixes. Limits: layout often shifts, and fonts that aren't installed get substituted. Check the result before sending.

6. Online tools (Smallpdf, Sejda and similar)

Convenient and full-featured, but they upload your file and free use is usually limited by tasks per day or hour. Limits change often, so check the current ones. Good for: non-sensitive documents and one-off tasks like merging or compressing.

7. A paid desktop editor (Acrobat Pro and others)

If you edit PDFs every week, a real desktop editor pays for itself, and some are sold as a one-time purchase instead of a subscription. Overkill if you only fill and sign.

Switching without losing work

  1. Download every document you need from pdfFiller before you cancel.
  2. If you're on a trial, check the cancellation terms and date first.
  3. Save your signature in the new tool and test one real form end to end.
  4. Open the finished PDF in a second app to confirm your entries were saved into the file.

FAQ

Is there a free pdfFiller alternative with no watermark?

Yes. Browser PDF viewers, Mac Preview and Acrobat Reader add no watermark. Penwise is free for filling, signing and downloading with no watermark. Some online tools put a watermark on free exports, so check before you spend time on a document.

Can I edit a PDF without uploading it?

Yes. Desktop apps and browser extensions work on your computer. Editing existing text is the weak spot of free tools; filling forms and adding text or signatures on top of the page works well locally.

Is pdfFiller worth it?

It can be, if you need cloud storage, templates and sharing in one place. If you only fill and sign documents occasionally, free local tools do the job without a subscription or uploading your files.

Are signatures from these tools legally valid?

Simple electronic signatures are generally valid for everyday agreements in the US (ESIGN, UETA) and the EU (eIDAS). Some documents need more. This isn't legal advice, so ask whoever sent the document what they accept.

Fill and sign PDFs in Chrome without uploading them. Penwise is free for filling, signing and downloading, and your files never leave your computer.
