Why convert ZIP to PDF

Manually unzipping and dragging 200 images into a PDF tool is tedious; here the archive is opened, files are sorted naturally (page1, page2, … page10) and assembled into one document.

Image-only archives are converted entirely in your browser. Archives containing Office documents are converted on our server, where each document becomes a section of the PDF.

How it works

  1. Drop ZIP file onto the box above, click it to browse, or paste from the clipboard.
  2. Adjust the options if you need to — the defaults suit most cases.
  3. Press Convert. Small files are handled on your device; larger ones are sent to our server with a progress bar.
  4. Download the PDF.

About the formats

ZIP · ZIP archive · .zip

The universal archive: several files bundled and compressed into one, opened natively on Windows, macOS, iOS and Android.

  • ZIP compresses each file separately, so already-compressed files (JPG, MP4) barely shrink.
  • ZIP supports password protection, but the classic ZipCrypto scheme is weak; AES-256 ZIPs need 7-Zip or WinZip.
  • A ZIP over 4 GB needs the ZIP64 extension, which very old tools do not read.

PDF · Portable Document Format · .pdf

The fixed-layout document standard: looks the same on every device and printer, which is why forms, invoices, contracts and reports are shared as PDF.

  • A PDF can contain vector text, embedded fonts, images, form fields, annotations and digital signatures.
  • Scanned PDFs are just pictures of pages; they need OCR before the text can be searched or copied.
  • PDF is an open ISO standard (ISO 32000) since 2008.
