PDF Toolbox – Merge & Compress

PDF Toolbox is a fast, offline PDF converter and editor toolkit for Android. Merge PDF files, split a PDF into multiple documents, compress a PDF's file size, and convert between images and PDF — all without an internet connection or an account.

Every tool processes files directly on your device. Nothing is uploaded to a server, you don't need to sign up or log in, and the app doesn't request access to your camera, contacts, or storage beyond the specific files you pick.

WHAT YOU CAN DO

Merge PDF files
Combine multiple PDF documents into a single file, in exactly the order you choose.

Split a PDF
Divide a large PDF into multiple smaller files by page range — useful for splitting a document into chapters, sections, or standalone handouts.

Extract PDF pages
Pull specific pages out of a PDF and save them as their own separate file, without touching the rest of the document.

Compress PDF file size
Shrink a large PDF with a simple quality slider, and see exactly how much smaller it got — handy when a file is too big to email or upload.

Convert image to PDF
Turn one or more photos into a single PDF. Reorder pages before converting, and sideways photos are automatically rotated upright.

Convert PDF to image
Export every page of a PDF as a PNG or JPEG image, packaged into one download.

Organize PDF pages
Delete pages you don't need, reorder pages, rotate any page, and insert new pages from photos — all in one screen before you save.
