Code generator

Pick a size limit, a tool and a language, and copy ready-to-paste code with a live preview.

The code updates as you change the options. Copy it into your page; nothing else is needed.

Shrink uploads before they fail

Add data-pdfkind-max to a file field. When a visitor picks a PDF or photo that is too big, PDFkind reduces it in their browser and your form receives the smaller file. iPhone photos (HEIC) are turned into JPG.

Size limit

HTML

<script src="https://pdfkind.com/embed.js" defer></script>

<input type="file" name="document" data-pdfkind-max="5MB">
<p>Large files are reduced in your browser by <a href="https://pdfkind.com/compress-pdf">PDFkind</a>.</p>

Or from your own code:

JavaScript

const small = await PDFkind.fit(file, { max: '5MB' });
