Frequently Asked Questions
Should I replace all my JPG images with WebP?
It depends on your audience and technical setup. If you can implement proper fallbacks and your users primarily use modern browsers, converting to WebP can significantly improve performance. However, keep JPG versions as backups for compatibility.
Will WebP work in email marketing campaigns?
Email client support for WebP is limited and inconsistent. For email marketing, stick with JPG (or PNG for images requiring transparency) to ensure your images display correctly across all email clients.
How much smaller are WebP files compared to JPG?
WebP files are typically 25-35% smaller than equivalent quality JPG files. The exact savings depend on image content, with photographs showing good compression and graphics with text showing even better results.
Can I use WebP for print projects?
Most print workflows still expect traditional formats like JPG, TIFF, or PDF. While WebP can be converted to these formats, it's generally better to work with JPG or TIFF directly for print projects to avoid unnecessary format conversions.
