PDF: what it’s for

PDF (Portable Document Format) freezes a document's layout so it looks identical everywhere: contracts, invoices, resumes, ebooks, manuals, and printable forms. Toolzum treats PDF as a working format — merge, split, compress, extract, and convert it entirely in your browser.

Strengths

  • Pixel-stable layout on every device, OS, and printer
  • Supports text, images, forms, annotations, and digital signatures
  • Our tools merge, split, compress, and convert PDFs with nothing uploaded
  • Text extraction works instantly when the PDF has embedded text

Honest limits

  • Scanned PDFs are just images of pages — text tools need OCR first
  • Not reflowable like EPUB: small screens get tiny text or awkward zoom
  • Image-heavy PDFs balloon in size; compress before emailing
  • Complex designer layouts may extract text out of reading order

Free PDF tools

Every tool runs in your browser — files never leave your device. Badges say exactly what each tool does with PDF.

PDF FAQs

Why can't I copy text from my PDF?

It is probably a scanned PDF — images of pages with no embedded text. Run it through PDF OCR first, then text extraction works.

How do I make a PDF smaller for email?

The PDF compressor re-encodes embedded images locally. Image-heavy scans often shrink by half or more with no readable difference.

Can I combine images into one PDF?

Yes — JPG to PDF converts photos page-by-page, and the PDF merger joins multiple PDFs into a single document, all locally.

Do PDF tools upload my documents?

No. Merging, splitting, compressing, and converting all run in your browser — sensitive documents never leave your device.
