10 Best Free PDF Tools You Should Bookmark in 2025

Why PDF tools matter more than ever

The Portable Document Format is almost 32 years old and still the lingua franca of professional documents. Invoices, contracts, research papers, government forms — they all live as PDF. Yet the tools to manipulate them have stayed surprisingly clunky: heavy desktop installs, limited free trials, or shady upload sites that quietly keep a copy of your contract.

In 2025, the better answer is browser-based tools. A modern browser can merge, split, rotate, compress and convert PDFs entirely on your device, using JavaScript libraries like pdf-lib. Nothing leaves your computer. No account. No watermarks. No "upgrade to download" bait-and-switch.

Here are the ten free PDF tools we think every knowledge worker should keep within reach.

1. Merge PDF

Combine multiple PDFs into one in the exact order you want. Perfect for assembling a portfolio, stitching scanned pages together, or attaching a cover letter to a resume.

Try the Merge PDF tool — drag in files, reorder, click merge.

2. Split PDF

Extract a clean range of pages — say, pages 1–5 of a 40-page report — into a new file. Useful for sharing only the relevant section without leaking the rest.

3. Compress PDF

Reduce file size by stripping metadata, optimizing object streams and removing duplicate resources. Browser-based compression has honest limits (it can't reconstruct image-heavy scans the way a server can), but for text-based PDFs it routinely shaves 20–40%.

Use the Compress PDF tool when email attachments bounce off size limits.

4. Rotate PDF

Fix the sideways scans. Rotate every page 90°, 180° or 270°, or apply per-page rotation when only some pages are wrong.

5. Extract PDF Pages

Pull specific pages into a new PDF without altering the original. Great for quoting excerpts or building a custom handout.

6. Delete PDF Pages

Remove unwanted pages — cover sheets, blank inserts, sensitive appendices — and save the rest as a clean document.

7. Reorder PDF Pages

Drag pages into a new sequence. Useful when a draft got assembled out of order or when you need to move an executive summary to the front.

8. PDF to JPG

Convert each page to an image for embedding in slides, social posts or design software. (Note: a true rasterization requires pdf.js; lightweight converters may render structural placeholders — read the tool's disclaimer.)

9. JPG to PDF

Turn a folder of photos — receipts, whiteboard snapshots, signed pages — into a single searchable PDF. Choose A4, Letter, or "fit to image" page sizing.

10. Extract Text (coming soon)

OCR and copy the text layer of scanned PDFs. Until then, copying from a PDF that already has a text layer works in any reader.

How to choose the right tool

A quick decision tree:

1. Combining documents → merge.
2. Pulling a section out → extract or split.
3. Shrinking for email → compress.
4. Reorganizing → reorder, rotate or delete pages.
5. Converting formats → PDF↔JPG.

Why browser-based wins for most workflows

• Privacy: contracts, medical records and IDs never touch a server.
• Speed: no upload time, no queue.
• Cost: free, no upsell.
• Offline: works on a plane.

Server-side tools still win for heavy OCR, layout reconstruction, or editing embedded vector graphics. For 90% of everyday PDF work, the browser is enough.

Conclusion

Bookmark a good browser-based PDF toolkit and you'll save yourself a dozen small frustrations a week. Start with Merge PDF and Compress PDF, then explore the rest as needs arise. Your contracts — and your inbox — will thank you.
