Best 6 PDF Apps for Filling, Signing, and Managing Forms Without Adobe

If you’ve ever needed to fill, sign, or manage a PDF form without Adobe Acrobat and found yourself frustrated by poor alternatives, you’re not alone. Adobe might be the industry leader, but it’s not the only game in town—and certainly not always the most cost-effective or user-friendly. Whether you’re managing contracts, applications, or personal tax forms, there’s a world of non-Adobe PDF apps that are efficient, intuitive, and often completely free or cheaper.

TL;DR:

Adobe Acrobat isn’t your only option when it comes to working with PDF forms. There are several powerful apps that let you fill in, sign, and manage PDFs efficiently—and without the heavy subscription fees. Options like PDF-XChange Editor, Smallpdf, and Foxit PDF offer comparable tools, many with free or low-cost versions. These alternatives work across devices and often include cloud storage, e-signatures, and collaboration features.

1. PDF-XChange Editor

Best for: Power users who want a rich set of features on Windows

PDF-XChange Editor has long been a favorite for professionals who want Adobe-level control without the Adobe price. It’s fast, packed with features, and surprisingly lightweight.

  • Form Functionality: Fill in both static and dynamic forms with ease
  • Signing Options: Includes digital signature support and image-based signing
  • File Management: Merge, split, and organize PDFs effortlessly
  • Extras: Built-in OCR to convert scanned documents into editable text

There’s a free version that includes most core functions, though advanced features may leave a watermark. It’s especially popular for Windows users looking for a powerful, non-cloud-based alternative.

2. Smallpdf

Best for: Quick, browser-based PDF work

If you just need to fill and sign a form without installing anything, Smallpdf is what you want. It’s a browser-based tool and available as both a web platform and mobile app.

  • Form Filling: Drag-and-drop simplicity for text fields and checkboxes
  • Signatures: Type, draw, or upload your signature for easy use
  • File Management: Convert files to PDF, split pages, compress PDFs
  • Cloud Integration: Connects directly with Google Drive and Dropbox

You can complete most tasks for free, though frequent users may want to consider their reasonably priced Pro plan. It also works on any device—great for filling out forms on the go.

3. Foxit PDF Editor

Best for: Enterprise users and collaboration

Foxit PDF Editor is often considered the best business-grade alternative to Adobe Acrobat. It offers many of the same core features but adds a few collaboration-oriented touches.

  • Forms: Create and edit interactive forms with full compatibility
  • Signing: E-signatures with audit trails for teams
  • Commenting: Add sticky notes, highlight text, and draft responses
  • Integration: Syncs with Microsoft Office, Google Workspace, and others

The UI might look a little old-school, but it gets the job done—and very effectively. Foxit comes in Windows, macOS, iOS, and Android versions, making it flexible for teams working across platforms.

4. PDFescape

Best for: Lightweight and occasional PDF editing

PDFescape offers a free online editor along with a downloadable desktop app. The focus here is ease-of-use and quick edits—ideal for users who don’t want to mess with complicated interfaces.

  • Signatures: Freehand draw signatures or upload an image
  • Extras: Annotate, whiteout content, and add sticky notes
  • Support: Works with all browsers, no account needed

The free version is fully functional for most tasks as long as the file size is under 10MB. If you find yourself needing extra storage or advanced features like file encryption, the premium version might be worth exploring.

5. Sejda PDF Editor

Best for: Beautiful UI and easy signing

Sejda has quietly become one of the most loved PDF editors thanks to its clean interface and solid features. It’s available both online and as a desktop app for Windows, macOS, and Linux.

  • Signature Process: Create searchable signature libraries
  • Safety: All documents auto-delete from servers in 2 hours
  • Speed: Optimized for fast performance even on older systems

The free plan has daily usage limits (3 tasks per hour), but for casual users, that’s usually more than enough. Premium packages are available without breaking the bank.

6. PDF Expert (macOS & iOS)

Best for: Apple users seeking premium design

PDF Expert by Readdle is designed for the Apple ecosystem and makes managing PDFs on Macs, iPads, and iPhones incredibly smooth. It blends functionality with the visual polish Apple fans love.
