Top 10 Free Online PDF Tools You Should Be Using in 2025
In today’s digital-first world, PDF documents are everywhere — from invoices and contracts to reports and resumes. But managing PDFs shouldn't mean shelling out money for expensive software like Adobe Acrobat. Luckily, there’s a whole world of free, online PDF tools that let you handle almost every PDF task right from your browser.
In this guide, we’ll cover 10 of the best free PDF tools available today — including one of the fastest ways to convert PNG images to PDFs with zero hassle.
1. 🖼️ PNG to PDF Converter (Free & No Watermarks)
If you’ve ever needed to convert images into a polished document format, this PNG to PDF tool is a must-have. It’s completely free, requires no signup, and supports batch uploads.
Key Features:
- Drag-and-drop simplicity
- Rearrange images before converting
- High-resolution output
- No watermarks, no limits
Why It Stands Out:
Unlike many converters, this tool retains image clarity and doesn't slap a watermark on your final file. It’s perfect for designers, students, or anyone needing to compile visual content into a shareable document.

2. 📚 Merge PDF Files
Combining multiple PDFs into one is a common need — whether you're consolidating reports, contracts, or scanned documents. Free merge tools let you upload files, arrange them in the right order, and export one cohesive PDF.
Best For: Legal teams, project managers, or educators managing multi-page content.
3. 📉 Compress PDF Files
Large PDFs can be a nightmare to email or upload. Online compressors reduce file size without significantly compromising quality.
Look For:
- Adjustable compression levels
- Preview before download
- Cloud-based (no installation)
Great for freelancers or marketers sending out high-volume PDFs.
4. 🖋️ Edit PDF Text & Images
Some free PDF editors allow light changes like adding text, annotations, highlights, or even replacing images.
Popular Uses:
- Filling out forms
- Adding e-signatures
- Making small content tweaks
While advanced editing is usually behind a paywall, these tools cover 80% of everyday tasks.
5. 📤 PDF to Word Converter
Need to update an old document but only have a PDF? Convert it to an editable Word doc in seconds.
Pro Tip: Choose a converter that retains formatting — especially for resumes, proposals, or multi-column layouts.
6. 📥 Word to PDF Converter
When you’ve finished editing a Word document and want to lock the format, convert it to a PDF for sharing.
Best Use Cases:
- Submitting resumes
- Sending branded documents
- Publishing eBooks
Many Word to PDF tools are 100% online and support drag-and-drop functionality.
7. 🔐 Unlock or Password-Protect PDFs
Sensitive info? Some tools help encrypt PDFs with a password. Others help unlock PDFs if you’ve forgotten the password (as long as it’s not DRM-locked).
Use With Caution:
Only use reputable sites for password-related PDF tasks to avoid privacy risks.
8. 🧩 Split PDFs
Split large PDF files into smaller parts by page numbers or bookmarks.
Perfect For:
- Sending specific chapters or slides
- Extracting key sections from reports
- Archiving documents more efficiently
9. 🖊️ Add eSignatures to PDFs
Whether you’re signing a contract or authorizing a form, free e-sign tools let you upload a file, drop in your signature, and send it securely.
Some even support multi-party signing with timestamps — useful for remote work or client approval.
10. 📄 Convert JPG/PNG to Other Formats
While we’ve covered PNG to PDF, many tools also convert images to other formats like JPG, Word, or even Excel using OCR (Optical Character Recognition).
Use Case: Digitizing handwritten notes or invoices into searchable text documents.
