You can merge multiple PDFs into one document or split large PDFs into smaller files using the FindUtils PDF Merger & Splitter — completely free, with no account required. Processing happens entirely in your browser — nothing is uploaded to servers, so your documents stay private.
Whether you're assembling a report from chapters or sending a single chapter to a colleague, FindUtils makes merging and splitting PDFs simple without desktop software.
Combine Reports — Merge chapters into complete documents Batch Processing — One PDF per table of contents instead of 10 files Standardization — Single document for backup and archiving Easy Sharing — One file instead of email attachments Professional — Complete report looks polished
Selective Sharing — Send only relevant pages to recipients Reduce Size — Smaller files for faster downloads Organize — Extract sections for different purposes Privacy — Remove sensitive pages before sharing Processing — Some tools have per-file limits (can split large PDFs)
Use the FindUtils PDF Merger & Splitter to combine or separate PDFs instantly in your browser.
Open the FindUtils PDF Merger & Splitter and upload your files. You can upload 2-10 PDFs depending on file size.
Drag and drop to reorder PDFs. Tools typically show thumbnails of first pages so you can verify order:
Click "Merge PDFs". Processing takes 5-30 seconds depending on total file size.
Download your combined PDF. It contains all pages from all source PDFs in order.
Upload the PDF file you want to split.
By Page Ranges
By Single Pages
Every N Pages
Before splitting, preview the pages you're extracting to ensure they're correct.
Click "Split" and download your PDFs. Each split file is independent and complete.
Task: Combine 5 chapters into one report
Result: complete-report.pdf (75 pages)
Process:
Task: Merge 10 page scans into one document
Result: document-complete.pdf (10 pages)
Process:
Task: Combine portfolio pieces into one PDF
Result: complete-portfolio.pdf
Process:
Task: Send only Chapter 3 to a colleague Original: 75-page report (chapters 1-5) Extract: Pages 31-50 (Chapter 3 only) Result: chapter-3.pdf (20 pages)
Task: Send report but remove salary information on page 42 Original: 50-page report with sensitive data Split: Pages 1-41, 43-50 (skip page 42) Result: public-version.pdf (49 pages)
Task: Split 500MB PDF into smaller chunks Original: 500MB (1000 pages) Split: Every 100 pages Result: 10 PDFs (50MB each)
Reason: Email limits (25MB), upload limits (100MB per file)
Task: Extract specific invoices from 200-page ledger Original: All invoices (200 pages) Extract: Pages for January, May, September Result: 3 PDFs (one per month)
Many tools merge not just PDFs, but also:
Example:
For merging 10+ PDFs, use command-line tools:
# macOS/Linux: Using pdfcat (or similar) pdfcat file1.pdf file2.pdf file3.pdf -o merged.pdf # Or using Ghostscript gs -sDEVICE=pdfwrite -o merged.pdf file1.pdf file2.pdf file3.pdf
Much faster than uploading to web tools.
Complete workflow combining multiple PDFs:
Source documents:
Merge in order: Upload in correct sequence, merge into: final-report.pdf (58 pages)
Compress (optional): Use PDF Compressor to reduce file size for distribution
Share: Send final-report.pdf to stakeholders
Send relevant sections to different recipients:
Original: complete-project.pdf (100 pages)
Split:
Download: 4 separate PDFs, each tailored to recipient
Email: Send relevant PDF to each group
Uploading PDFs in wrong order creates confusing merged result.
Right: Upload in order (Chapter 1, 2, 3...) Wrong: Random order (Chapter 3, 1, 2...)
Fix: Reorder using drag-and-drop before merging.
Merged PDF defaults to generic name "merged.pdf" or "combined.pdf".
Right: Rename after download: "final-report.pdf" Wrong: Keep generic name, lose context
Always keep source PDFs backed up. Merging deletes them from temporary storage.
Workflow:
Extracting single pages creates too many files. Use page ranges instead.
Right: Extract pages 1-20 as one PDF Wrong: Extract pages 1, 2, 3, 4... (20 separate PDFs)

FindUtils processes all merge and split operations locally in your browser, meaning your documents never touch a third-party server. Competitors like iLovePDF and Smallpdf upload your files for server-side processing.
Q1: How many PDFs can I merge? A: Typically 10-20 depending on file size and tool. Online tools have combined size limits (usually 100-500MB total).
Q2: Does merging reduce quality? A: No. Merging preserves all original content and quality.
Q3: Can I merge PDFs with different page sizes? A: Yes. Most tools align pages left-top and merge. Result may look odd if sizes vary dramatically.
Q4: Is the merged PDF secure? A: As secure as the source PDFs. Merging doesn't add or remove security. On findutils.com, processing happens entirely in your browser — nothing is uploaded to servers, so your documents stay private throughout the process.
Q5: How do I split a specific page range? A: Upload the PDF, choose "by page range," enter start and end pages (e.g., 10-20), and split.
Q6: Can I split every other page? A: Yes, some tools support custom page selection. Click individual pages to select or deselect.
Q7: What if split PDFs are too small? A: You're extracting too few pages. Use larger page ranges (e.g., 1-50 instead of 1-10).
Merge with clarity, split with precision! 📄
