How to use PDF Tools

Choose the tool for the job from the groups below, or press Ctrl+K anywhere and type its name.

Set the options, check the preview, and download the new PDF.

Frequently asked questions

Are these PDF tools really free?

Yes. Every PDF tool here is free to use with no account, no sign-up and no watermark added to your files.

Are my PDFs uploaded to a server?

No. The PDF tools use pdf.js, pdf-lib and qpdf compiled to WebAssembly, so your files are read and written in your browser and never sent anywhere. The only exception is OCR, which downloads its language data the first time; your PDF still stays local.

How do I sign a PDF?

Open Edit PDF and choose Sign. Type, draw or upload a signature, then click where it goes. Signatures are saved in your browser for next time. This adds a visible signature, not a certificate-based digital signature.

Is there a file size limit?

There's no set limit. Because the work happens on your device, the practical limit is your browser's memory: large files work on a laptop, while a phone may struggle with very large scans.

Can I convert Word, Excel or PowerPoint to PDF?

Not yet. Converting to PDF works from images with JPG to PDF. Converting from PDF works to Word, Excel, PowerPoint, JPG and Markdown.

Can I use the PDF tools on my phone?

Yes. They run in any modern mobile browser, and Scan to PDF can use your phone's camera to photograph documents.

What's in the PDF toolkit

Edit: change existing text, add text, images, shapes and signatures, and fill or add form fields in Edit PDF; add page numbers or a watermark, or crop the pages.
Organize: merge several PDFs, split one into files, remove or extract pages, reorder them in Organize PDF, rotate them, or scan paper into a PDF.
Optimize: compress a PDF to a smaller size, repair a damaged one, or make a scan searchable with OCR.
Convert: JPG to PDF, and from PDF to JPG, Word, Excel, PowerPoint and Markdown.
Security: add a password with Protect PDF, remove one you know with Unlock PDF, black out text for good with Redact PDF, or compare two versions.

Common jobs

A form or portal rejects your PDF as too large: compress it, and check the new size before you upload.
You have several scanned pages or certificates to send as one file: merge them, or turn phone photos into one PDF with JPG to PDF.
You need to fill and sign a form: type on it and add your signature in Edit PDF.
You need the text of a scanned PDF: run OCR, or turn the PDF into an editable document with PDF to Word.

Why no upload matters

Most online PDF services upload your file to their server, process it there, and promise to delete it later. Here the file is never sent, so there is nothing to delete and no copy on anyone else's computer. That matters for contracts, ID documents, bank statements and medical records. It also means no waiting for uploads on a slow connection.
