Module 03

PDF Tools

Merge or split PDFs, build a PDF from images, or export PDF pages as JPG images. Everything runs in your browser — files are never uploaded.

Merge PDF

Combine multiple PDF files into one. Reorder before merging.

Split PDF

Extract specific pages or split every page into its own file.

JPG to PDF

Turn multiple images into one PDF. Fit to A4 or keep original size.

PDF to JPG

Export every PDF page as a JPG inside a .zip.

Privacy-first

All processing happens client-side in your browser. Your PDF and image files are never uploaded to LentoCircle servers — they never leave your device. File count and size are limited only by your browser's own memory.
