Everything you can do to a PDF file entirely in your browser — merge, split, compress, rotate, watermark, protect, remove passwords, extract text, and convert to images.
Drag all your PDF files into the Merge PDF tool and arrange them in the desired order. Click Merge to generate a single combined PDF. Files are processed entirely in your browser using the pdf-lib library — no size limit imposed by server upload restrictions.
Use the Password Protect PDF tool. Choose 'Password to open' if you want readers to enter a password before viewing the file. Choose 'Restrict permissions only' if you want anyone to open the file but prevent printing, copying, or editing — set an owner password to lock those restrictions. The PDF is encrypted with RC4-128 bit encryption.
Upload the encrypted PDF to the Remove PDF Password tool and enter the current password. The tool verifies the password against the PDF's stored encryption parameters and decrypts all streams and strings using RC4. The output PDF has no encryption and opens without a password prompt. Note: this only works with RC4-encrypted PDFs (the most common type). AES-encrypted PDFs are not supported.
The Compress PDF tool reprocesses your PDF using object streams, which packs indirect objects more tightly. This reduces file size most on PDFs with many small objects (forms, annotated documents, complex metadata). Content images are not resampled, so the visual quality is preserved.
