Does Outlook support WebP images in emails?

No. Outlook on Windows does not render WebP images and displays a broken image placeholder instead. Converting to JPEG or PNG before inserting images into email campaigns ensures all recipients see the image correctly.

Will WordPress accept WebP uploads?

WordPress added native WebP support in version 5.8, but many hosting configurations, older themes, and plugins still have compatibility issues. Converting to JPEG or PNG eliminates these edge cases entirely.

How many images can I convert at once for a publishing batch?

Up to 50 images per batch, with a 2GB total size cap. This covers a typical week's editorial image volume in a single conversion job.

Is PNG or JPEG better for infographics published on the web?

PNG is better for infographics because it uses lossless compression, preserving sharp text and line edges. JPEG compression can introduce visible artifacts around text and fine detail.

Convert WebP Images to JPEG or PNG for Editorial and CMS Publishing Workflows

Editorial teams and content publishers frequently receive WebP images from developers, designers, or web scrapers — only to find that WordPress, HubSpot, Mailchimp, and other publishing platforms either reject the format or render it inconsistently across email clients. Deliteful converts WebP to JPEG or PNG so images move through your publishing pipeline without manual workarounds.

Content publishing workflows are deadline-driven. A rejected image upload in WordPress or a broken image in an email campaign preview can delay an entire publication cycle. WebP has inconsistent support across email clients — Outlook in particular does not render WebP — making JPEG or PNG the only safe formats for email distribution. Converting before upload is the only reliable fix.

For high-volume editorial schedules, batch conversion of up to 50 images at once means a week's worth of inline article images can be converted and ready for CMS upload in a single job. JPEG is the standard for photographic editorial content; PNG is appropriate for diagrams, charts, and infographics where transparency or lossless rendering matters.
