Free PDF to WebP Converter

Instantly convert your PDF documents into a ZIP file of high-quality WebP images. This free tool runs 100% on your device, meaning your files are never uploaded.



Why This Tool is 100% Private (Our E-E-A-T)

As developers and bloggers at Rekreay, we were frustrated with online PDF tools. They all require you to upload your sensitive files—invoices, private contracts, personal documents—to a random server. This is a huge privacy risk.

We built this tool to be the one we always wanted: 100% private, fast, and free. It's a core part of our Rekreay mission to provide high-quality, AdSense-compliant tools you can actually trust.

This tool works 100% in your browser. Your files are never uploaded to any server, giving you total privacy and instant results. All the conversion logic happens locally on your computer using JavaScript.

  • No Uploads: Your PDF never leaves your device.
  • Browser-Based: We use the open-source pdf.js library to read the PDF and the JSZip library to create the ZIP file, all 100% within your browser.
  • Total Security: Because your data is never sent to a server, there is zero risk of your sensitive documents being seen, stolen, or stored.

This in-browser method is the safest and fastest way to convert your PDFs while guaranteeing your data remains 100% private.

How This Tool Helps Your Tech Blog

As a fellow tech blogger, this tool was built to solve our own problems—especially around site speed and AdSense.

1. Fix Core Web Vitals (Site Speed)

JPGs and PNGs are old and heavy. Google loves fast sites, and Core Web Vitals (CWV) are a key ranking factor. Converting your images to WebP makes them 25-35% smaller with no quality loss. A faster site means a better user experience, which is critical for AdSense approval.

2. Create AdSense-Friendly Content

Have a multi-page PDF guide on 'Python coding tips'? Embedding a PDF in your blog is clunky, bad for SEO, and bad for user experience. Use this tool to convert each page into a lightweight WebP image. Then, display them as a clear, in-line visual gallery that readers can easily see (and Google can index as an image).

3. Extract Visuals for Tutorials

Need to grab a single slide or architecture diagram from a lengthy PDF presentation for your next "Future of AI" slideshow? This tool lets you extract it as a high-quality image without needing complex software.

How to Use This Secure PDF Converter

  1. Select Your PDF: Click the "Choose File" button to select the PDF document from your computer.
  2. Click Convert: Press the "Convert to WebP" button. You will see a "Converting..." status message.
  3. Download Your ZIP: A green "Download WebP Files (ZIP)" link will appear. This ZIP file contains all your PDF pages as separate, high-quality WebP images.

Frequently Asked Questions (FAQ)

Why should I use WebP instead of JPG?

WebP is a modern image format made by Google. It provides the same (or better) quality as a JPG or PNG, but at a much smaller file size. Using WebP makes your website load faster, which is better for SEO and user experience.

How does this tool help with AdSense approval?

AdSense uses many signals for approval, and two of the most important are User Experience and Site Speed (Core Web Vitals).

  • By converting your images to WebP, you make your site load significantly faster, which directly improves your Core Web Vitals score.
  • A fast, professional-looking site signals quality and trust to the AdSense review team.
Are my files safe? You don't upload them?

Your files are 100% safe. The "no upload" feature is the most important part of this tool. The entire conversion process happens inside your web browser on your own computer. Your PDF file never leaves your device, so your privacy is completely guaranteed.

Will the converted WebP images be high quality?

Yes. The converter is set to a high-quality (90%) compression level for the WebPs. This provides a great balance of sharp, clear images and small file sizes that are perfect for web use, blogs, and social media.

Why do the converted images come in a ZIP file?

If your PDF has multiple pages (e.g., 10 pages), the tool converts each page into a separate WebP file. A ZIP file is the easiest and fastest way to bundle all 10 of those new WebP images into a single, convenient download for you.
