PDF Tools
Free online PDF tools
Thirteen focused tools cover everything people actually do with PDFs — merging, splitting, compressing, securing, signing and converting. Every one runs entirely in your browser: your files are processed on your own device and never uploaded to a server.
Merge PDF
Combine multiple PDF files into one document in the order you want.
Split PDF
Extract pages or split a PDF into separate files in a couple of clicks.
Compress PDF
Reduce PDF file size while keeping quality — great for emailing.
Rotate PDF
Rotate pages 90°, 180°, or 270° — the whole document or just selected pages.
PDF to Word
Convert PDF documents into editable Word (.docx) files instantly.
Protect PDF
Encrypt a PDF with a password (AES-256) so only people you choose can open it.
Unlock PDF
Remove password protection from a PDF you have access to — enter the password, download freely.
Sign PDF
Add a signature or initials to a PDF and download the signed copy.
Add Watermark
Add a text or image watermark to every page of a PDF in seconds.
Add Page Numbers
Add page numbers to every page of a PDF — 6 positions, 4 formats, custom start & skip-first-page.
JPG to PDF & PDF to JPG
Turn JPG/PNG images into a single PDF, or convert each PDF page into JPG images — in your browser.
OCR Scanned PDF
Extract text from scanned, image-only PDFs with OCR — download plain text or a searchable PDF.
Word to PDF
Convert .docx Word documents to PDF in your browser — headings, paragraphs and lists preserved.
Working with PDFs, privately
Most online PDF tools upload your document to a server before doing anything with it. Ours don't. Codrenix Toolbox loads the processing library into your browser, so merging, compressing and converting happen locally — the practical limit is simply your device's memory. Close the tab and everything is gone.
Not sure where to start? Merge PDF combines several documents in order, Compress PDF shrinks large files for email, JPG to PDF & PDF to JPG moves between document and image formats, and OCR Scanned PDF pulls selectable text out of scans. You can also browse the full toolbox or read how we handle your files on the security page.

Are my PDFs uploaded to a server?
No. The processing libraries load with the page and run on your own device, so your file never leaves your browser. See the security page for the full technical explanation.
