Free PDF Tools that respect your privacy
Working with PDFs usually means uploading confidential documents to a stranger's server. Our PDF tools don't: they use the open-source pdf-lib engine to edit documents directly on your device. Combine files, pull out pages, shrink large PDFs and turn images into PDFs without anything being uploaded.
Every tool runs in your browser — nothing is uploaded.
Frequently asked questions
Are my PDFs uploaded anywhere?
No — every PDF tool runs locally, so your documents stay private.
Is there a page or size limit?
No artificial limits; performance depends on your device's memory.
