What Are PDF Tools?
PDF (Portable Document Format) is the universal standard for sharing documents that maintain their formatting across all devices.

Built on pdf-lib and PDF.js, all operations run locally in your browser for maximum privacy and speed.

FAQ
Are my documents secure?
Yes, all PDF files are processed locally in your browser using JavaScript libraries (pdf-lib and PDF.js). Your documents are never uploaded to our servers or any cloud service. This is especially important for confidential contracts, financial documents, or personal files. You can verify this by monitoring network activity β no file data is transmitted.
Is there a size limit?
There are no hard server-side limits since processing happens on your device. Files up to 100MB typically process smoothly. For very large documents (200+ pages), processing time depends on your device's RAM and CPU power. We recommend using a desktop browser for the best experience with large files.
What formats are supported?
For PDF creation, we support converting JPG, PNG, and WebP images into PDF documents. For PDF export, you can convert PDF pages to JPG, PNG, or WebP images. Additionally, we support merging multiple PDFs, splitting documents into individual pages, and compressing PDF file size β all directly in your browser.
