AICKO PDF: Free PDF Editor for Windows
AICKO PDF is a free PDF editor for Windows that lets you read, edit the text, reorder pages, merge, compress, sign and convert a PDF to Word or images, with no subscription, no account and no internet connection.
It is a free alternative to Adobe Acrobat and to online PDF converters: everything happens on your computer, so your documents are never uploaded to a server. It joins AICKO WORD and AICKO TABLE, the two other free programs of the suite.
AICKO PDF, your PDF made simple
One program to do everything with your PDFs: fix a typo, delete a page, sign a contract, shrink a file or turn a worksheet into a fill-in-the-blank handout for your class.

Made for teachers
The Teacher tab gathers the classroom tools: turn a page into a fill-in-the-blank worksheet, split the questions from the answer key, print as an A5 booklet or 2 or 4 pages per sheet, and create a dyslexia-friendly version that is easier to read. The Maths PDF worksheets open in it directly.
