How CleanPDF works

Every tool on CleanPDF runs inside your web browser. When you choose a file, your browser reads it from your device, processes it with open-source libraries such as PDF.js, pdf-lib and, for OCR, Tesseract, and hands you the result as a download. There is no upload step and no server that receives or stores documents.

Check it yourself

  1. Open your browser's developer tools (F12 on Windows, Option + Command + I on a Mac) and choose the Network tab.
  2. Use any tool on a file.
  3. You will see the site's own scripts load, but no request that sends your document anywhere.

CleanPDF uses Google Analytics to count page visits. It never receives your files or their contents; the privacy policy explains what is collected.

A PDF compressor that keeps text as text

Many online compressors make a PDF smaller by turning every page into a picture. The file looks the same, but its text can no longer be searched or copied, and job-application systems cannot read it. Compress PDF on CleanPDF only shrinks the images inside the file. In our tests a 1.13 MB CV with a photo came down to 70 KB and stayed fully searchable. You can also set an exact limit, such as 100 KB, 500 KB or 1 MB, or compress many PDFs at once.

Good to know

  • File size: nothing is uploaded, so there is no upload limit. Very large files, such as hundreds of scanned pages, depend on your device's memory and are slow on phones.
  • Password-protected PDFs must be unlocked with Unlock PDF before other tools can open them. You need the password.
  • Works offline after loading: once a tool has loaded on your device, it keeps working if your connection drops.
  • Free: no account, no watermark and no daily limit.
