Two pinned notes saying PDF

PDF search engines make it easier to find free PDF eBooks, PDF files and other document files that might be overlooked by search engines with a wider focus. Looking for document files using a dedicated search engine lets you view results in specific formats, filtering out formats so documents are easier to find.

Docjax
Docjax searches common document files like Word, Excel and Powerpoint as well as PDF files. PDF files open in the browser (if that's the browser setting), other formats download. Docjax has over 320,577 documents from 3,296 websites. If you're looking for a document search minus eBooks, give Docjax a try.

PDFSearchEngine
PDFSearchEngine searches PDF, CHM, Word (Doc and Docx), RTF and TXT files. There are 512,727,964 searchable items in the database. No ads, clean interface and the choice of formats make it easier to get results.

FreeFullPDF
FreeFullPDF aims to increase the visibility and ease of use of open access scientific journals, theses, posters and patents. All scientific subjects are covered and all content are freely available in PDF format. Search and download free scientific publications on life sciences, health sciences, physics, mathematics, social science & humanities. You can search all the articles, or specific areas; thesis, review, patent, clinical trial, proceeding, curriculum vitae and poster. At the moment, there are more than 80 million PDF files. Results display a thumbnail of each listing.

Open PDF
Open PDF searches PDF files and eBooks for results. You can download a PDF or view it in the PDF Viewer. To use the PDF Viewer put the address of the file you want to see and click "View". The PDF Toolbar is no longer available. The first three search results are ads, if they are eBooks they go to a link to purchase the book.

soPDF
soPDF has more than 485,000,000 available PDF files. If you're searching for just PDF files that's the only file format you'll find here. The top three results are ads, and the upgraded website message at the top takes you to the French version of the site.

Specialized search engines can make searching a little easier and increase the chances of finding what you're looking for. If you're looking for PDF or other document files or eBooks try one of these.
