PDF

ArrayKit's PDF tools cover the everyday document work that usually means juggling clunky web converters. Combine files with Merge PDFs, pull out the pages you need with Split PDF, and slim down oversized documents with Compress PDF before sharing. You can convert with Image to PDF and PDF to Text, clean up layouts using Organize PDF, Rotate PDF and Crop PDF, then finish with Add Page Numbers or Watermark PDF. Need to spot changes between two versions? Compare PDFs diffs the extracted text line by line. These tools are built for students, office workers, developers and anyone handling contracts, reports or scanned paperwork. Everything runs entirely in your browser: each PDF is processed locally on your machine, nothing is uploaded to a server, and your files never leave your device, so even sensitive documents stay private while you work.

• Merge PDFs — Combine multiple PDFs into one, with reordering.
• Split PDF — Extract pages or ranges (e.g. 1-3,5,7-9) into a new PDF.

• Watermark PDF — Add a diagonal text watermark to every page.
• Crop PDF — Trim margins from every page via the crop box.
• PDF to Text — Extract selectable text from a PDF as plain text or Markdown.

• Compress PDF — Shrink a PDF by re-rendering each page to a JPEG at a chosen quality and resolution.

Frequently asked questions

Are these PDF tools safe to use with sensitive documents?

Yes. Every ArrayKit PDF tool runs entirely in your browser. Your files are processed locally on your device and nothing is uploaded to a server, so confidential contracts, reports and scans never leave your machine.

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 processing 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 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.

How do I combine several files into one PDF?

Use Merge PDFs to join multiple documents and reorder them before exporting. To turn pictures into a document, Image to PDF combines JPGs and PNGs into a single PDF in auto, portrait or landscape layout.

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.
