PDFs are the universal document standard in business, legal, academic, and marketing workflows, yet most dedicated PDF software costs hundreds of dollars per year. Our free PDF tools cover every common operation - merging, splitting, scanning, watermarking, password-protecting, converting to images, and updating metadata - all without leaving your browser and without any file being sent to a remote server.

Why Use Our PDF Tools?

End-to-End Privacy

PDF files contain sensitive information. All our PDF processing is done client-side using PDF-lib and pdf.js. Documents are never transmitted to or stored on external servers.

No Page Limits

Merge 50 PDFs or split a 500-page document - there are no artificial page caps. Processing speed depends only on your device.

Mobile Document Scanner

Use your phone camera to scan physical documents, apply perspective correction and greyscale filters, and export a multi-page PDF in seconds.

AES-256 Encryption

Our PDF password protector uses industry-standard AES-256 encryption - the same standard used by banks - to lock your documents before sharing.

Common Use Cases

1Merge client proposals, contracts, and appendices into a single branded PDF for cleaner email delivery.
2Split a 200-page annual report into individual chapter PDFs for targeted distribution.
3Scan invoices and receipts using your phone camera and export as PDF for expense claims.
4Password-protect confidential HR documents before emailing across departments.
5Watermark a PDF portfolio with your agency's logo before sharing with prospects.
6Convert PDF slides to high-resolution PNG images for use in social media or presentations.

Pro Tips

Tip 1: When merging PDFs, use drag-and-drop reordering to arrange pages before downloading - this saves a second merge pass.

Tip 2: For scanned documents, apply the 'Black & White' filter to drastically reduce file size while keeping text crisp and legible.

Tip 3: Set both a User password (to restrict opening) and an Owner password (to restrict editing/printing) when protecting sensitive documents.

Tip 4: Always strip PDF metadata before sharing public-facing documents - embedded author names, software versions, and creation dates can expose internal info.

Frequently Asked Questions

Are my PDFs uploaded to your servers?

No. All PDF operations use PDF-lib and pdf.js running entirely in your browser. Your documents stay on your device at all times.

Can I merge password-protected PDFs?

Currently, our merger requires unprotected PDFs. Decrypt your PDF first using a desktop tool, then merge using our tool.

What encryption standard does the PDF Password Protector use?

We use AES-256 encryption, the same standard used by financial institutions. This is the strongest encryption available in the PDF specification.

How many pages can I scan at once with Scan to PDF?

There is no page limit. Capture as many pages as you need using your camera. Each capture adds a new page to the document before you export the final PDF.
