Is the PDF to WebP converter free?

Yes, AstraPDF's PDF to WebP converter is completely free with no page limits, no account required, and no watermarks on the output images.

Is my PDF secure when I convert it?

Absolutely. All conversion happens directly in your browser using JavaScript. Your PDF file is never uploaded to any server, so your data remains completely private.

What is the difference between WebP and JPG?

WebP produces files that are typically 25–34% smaller than JPG at the same visual quality. WebP also supports transparency (alpha channel), which JPG does not. JPG has broader compatibility with older software, while WebP is natively supported in all modern browsers.

Can I convert a multi-page PDF to WebP?

Yes. Every page in your PDF is converted to a separate WebP image and downloaded automatically. There is no page limit.

Which quality setting should I choose?

Use Standard quality (0.85) for web publishing, social media, and apps — it produces noticeably smaller files. Choose High Quality (0.95) when you need to print the images or inspect fine details.

Which browsers support WebP images?

WebP is supported natively in all modern browsers including Google Chrome, Mozilla Firefox, Apple Safari (version 14+), and Microsoft Edge. It is the recommended image format for web use by Google.

Can I convert WebP images back to PDF?

Not directly, but you can convert your images back to PDF using the JPG to PDF tool on AstraPDF after saving the WebP as a JPG. AstraPDF offers a full suite of PDF tools to handle any workflow.

Does WebP support transparency?

Yes. WebP supports alpha-channel transparency, which means backgrounds that are transparent in the original PDF will remain transparent in the WebP output — unlike JPG, which forces a white or colored background.
