JPEG vs PNG vs WebP: Technical Comparison
Pick the right format every time. Here is a head-to-head breakdown of the three main image formats used on the web today.
Format-by-format comparison
To make the right choice when integrating your media, here is a summary of the technical characteristics of the three main image formats used on the internet.
| Technical criterion | JPEG | PNG | WebP (our tool) |
|---|---|---|---|
| Compression type | Lossy | Lossless | Hybrid (lossy or lossless) |
| Transparency support | No (auto white/black fill) | Yes (full Alpha channel) | Yes (ultra-light transparency) |
| Average file size | High for good quality | Very high (can slow the site) | Ultra-reduced (up to 80 % saving) |
| Ideal for… | Complex photographs | Logos, icons, transparent graphics | All your visuals and web media |
| Google SEO impact | Neutral (aging standard format) | Penalizing if not optimized | Strongly recommended by Google |
Which format should you choose?
For most modern websites: WebP
WebP combines the best of JPEG (efficient compression) and PNG (transparency support) into a single file format, with much smaller file sizes. It is the format Google itself recommends for web images.
JPEG still has a niche
Use JPEG only if you specifically need maximum compatibility with very old systems that do not support WebP. As of 2026, more than 97 % of browsers support WebP natively.
PNG: keep for source files
PNG remains an excellent format for editing source files where you need lossless quality, but convert them to WebP before publishing online.
