Frequently Asked Questions

Do you have Questions for JPG vs PNG vs WEBP ?

Let's connect and discuss your project. We're here to help bring your vision to life!

Use WebP for most images since it offers smaller file sizes with great quality, improving loading speed and Core Web Vitals. JPG is a reliable fallback for photos, and PNG remains best for logos or graphics requiring transparency.
Smaller optimized images reduce Largest Contentful Paint (LCP) and prevent layout shifts, enhancing user experience and helping search engines rank pages higher.
Modern browsers like Chrome, Firefox, Safari, and Edge support WebP widely. However, legacy browsers and some email clients may still need JPG or PNG fallbacks.
We recommend Squoosh.app, ImageOptim, the cwebp command‑line tool, ImageMagick for conversion, and WordPress plugins like ShortPixel, Imagify, or EWWW.
Use SVG for vector logos and icons to stay crisp at any size. For raster graphics, choose WebP or PNG with proper compression and dimensions while keeping branding guidelines.
Employ responsive images with srcset and sizes attributes, lazy‑load off‑screen images, preload critical above‑the‑fold assets, and serve images via a CDN that auto‑converts to optimal formats.
Yes, for email newsletters, print workflows, or when pixel‑perfect lossless files are required, JPG and PNG remain the safest choices.
With automated CI/CD pipelines, smart CDNs, and batch processing plugins, image optimization can scale across thousands of pages, reducing bandwidth and improving speed without manual effort.
