PDF Tools

ArrayKit's PDF tools cover the everyday document work that usually means juggling clunky online converters. Combine files with Merge PDFs, pull out the pages you need with Split PDF, and shrink oversized documents with Compress PDF before sharing. Rearrange layouts using Organize PDF, Rotate PDF and Crop PDF, then finish with Add Page Numbers or Watermark PDF. Convert both ways with Image to PDF, PDF to Images and PDF to Text, and spot changes with Compare PDFs, which diffs two versions line by line. When a file is sensitive, Encrypt PDF adds a password with AES-256, and Decrypt PDF removes it once you have the password. These tools suit students, office workers, developers and anyone handling contracts, reports or scans. Everything runs entirely in your browser: each PDF is processed locally and never leaves your device, so even confidential documents stay private.

Frequently asked questions

Are these PDF tools safe to use with sensitive documents?

Yes. Every ArrayKit PDF tool runs entirely in your browser. Files are processed locally on your device and nothing is uploaded, so confidential contracts, reports and scans never leave your machine. For extra protection you can also add a password with Encrypt PDF.

Do the PDF tools work offline?

Once the page has loaded, the tools run on your own device, so you can merge, split, rotate and compress PDFs without a steady connection. The work happens locally rather than on a remote server.

Will compressing or converting a PDF reduce its quality?

Compress PDF lets you choose a JPEG quality and resolution, so you control the balance between file size and clarity. Page-level tools like Merge, Split, Organize and Rotate rearrange pages without re-encoding their content.

Can I extract text or images from a PDF?

Yes. PDF to Text pulls selectable text out as plain text or Markdown, and PDF to Images renders each page to PNG or JPG that you can download. Both run locally in your browser.

Can I password-protect a PDF or unlock one?

Yes. Encrypt PDF adds open and owner passwords with AES-256 or RC4 and can restrict copying or editing. Decrypt PDF removes password protection once you enter the correct password, all on your device.

Is there a limit on how large my PDF can be?

Because processing happens on your own device, practical limits depend on your computer's memory rather than a server quota. Most everyday documents handle smoothly; very large scans may simply take a little longer.
