What is WebP format and why should I use it?
WebP is a modern image format developed by Google. It provides 25-35% smaller files than JPEG at the same visual quality. All major browsers (Chrome, Firefox, Safari, Edge) support WebP since 2020.
How do I convert JPG to WebP?
Upload your JPG files and they are automatically converted to WebP. Adjust the quality slider (80% recommended for photos) and download. For multiple files, use the ZIP download option.
Is WebP better than JPEG for websites?
Yes, WebP is 25-35% smaller than JPEG at equivalent visual quality. This means faster page loads, lower bandwidth costs, and better Core Web Vitals scores. The only downside is older browsers may not support it.
Does WebP support transparency like PNG?
Yes. WebP supports full alpha transparency like PNG, but with much smaller file sizes. A transparent WebP is typically 50-70% smaller than the equivalent PNG.
Can I use WebP for email attachments?
Not recommended. Many email clients and older devices cannot display WebP. Use JPEG for maximum email compatibility. WebP is best for websites and modern applications.
How do I convert HEIC to WebP?
Upload HEIC files directly. They are automatically converted to WebP. This is useful for using iPhone photos on websites, as HEIC is not web-compatible but WebP offers excellent compression.
What quality setting should I use for WebP?
80% for photos, 90% for graphics with text or sharp edges. WebP quality works differently than JPEG - 80% WebP often looks as good as 90% JPEG while being smaller.
Why are my WebP files larger than the original JPEG?
This happens with already heavily compressed JPEGs. WebP excels at compressing from high-quality sources. Try lowering the quality slider, or the original JPEG was already optimally compressed.
Is WebP supported on iPhone and Safari?
Yes since iOS 14 (2020) and Safari 14. All modern Apple devices fully support WebP for viewing and saving. Older iOS versions cannot display WebP images.
