When to Convert
Common scenarios where this conversion is useful
Embedding PDF content in blog posts
CMS platforms like WordPress display images natively but require plugins for PDFs. Converting to WebP gives you the smallest possible image file for fast page loads while maintaining visual quality.
Creating web-optimized document previews
Document listing pages, search results, and file managers need lightweight thumbnails. WebP previews of PDF pages load faster than PNG or JPG alternatives.
Email newsletter content
Email clients can't render PDFs inline. Converting a PDF flyer or report page to WebP produces a compact image that loads quickly in email, reducing bounce rates from slow-loading messages.
Reducing bandwidth for document-heavy sites
If your site displays many PDF page previews, WebP's superior compression reduces total bandwidth by 25-35% compared to JPG, directly cutting hosting costs.

Frequently Asked Questions
WebP produces files 25-35% smaller than JPG at equivalent visual quality. For web publishing, this means faster page loads and lower bandwidth costs. All modern browsers (Chrome, Firefox, Safari, Edge) support WebP.
The PDF is rendered at 300 DPI before WebP compression. The resulting image has the same pixel dimensions as our PNG or JPG converters — approximately 2550×3300 for a letter-size page.
Office 365 and Office 2021+ support WebP images in Word, PowerPoint, and Excel. Older Office versions may not. If you need broad Office compatibility, use JPG or PNG instead.
WebP is optimized for screen display, not print. While the 300 DPI rendering is detailed enough, WebP's lossy compression may introduce subtle artifacts. Use PNG or TIFF for print-quality output.
The converter processes the first page of your PDF. Multi-page conversion is planned for a future update. For now, you'll receive a single WebP image of page one.
WebP lossy compression typically produces files 70-80% smaller than PNG for the same visual content. A 5MB PNG of a PDF page might compress to 500KB-1MB as WebP with nearly identical visual quality.
Yes, as of 2023. Chrome, Firefox, Safari (14.1+), Edge, and all Chromium-based browsers support WebP. Only very outdated browsers lack support.
Not directly through this tool, but you can convert WebP to JPG or PNG first, then use those formats to create a new PDF. The original PDF should be kept as your primary document.
Files are uploaded via encrypted TLS, processed on our servers, and immediately auto-deleted after conversion. We never store, view, or log your documents.
The web converter accepts PDFs up to 25MB (free tier; 500MB on Pro). The authenticated API supports up to 500MB for larger documents.
