FORMAT
QUALITY
WebP is the format the modern web runs on: one container that does lossy photos, lossless graphics, and transparency, built to replace JPG and PNG at once.
Pros
- Smallest files at matching quality
- Transparency and compression together
- Every modern browser reads it
Cons
- Older design tools and some upload forms refuse it
- Sharing one with a non-tech friend often ends in a conversion
When to use it on a site
- Content images, thumbnails, and screenshots in docs or blog posts
- The default
<img>format when you'd rather not manage a<picture>fallback chain - Skip it for og:images; some link scrapers still want JPG or PNG there
AVIF compresses another 30 percent harder, but WebP still wins on the number of tools that open it. The practical pattern in 2026: serve WebP, keep a JPG for everything that leaves the web.
JPG has been the photograph's format since 1992: lossy compression tuned for the smooth gradients of real-world images.
Pros
- Opens absolutely everywhere
- Compact for photographs
- Safe for email, print shops, old software
Cons
- No transparency, backgrounds go white
- Text and sharp edges smear
- Every re-save loses more detail
When to use it on a site
- og:image and Twitter card images, the safest bet for every scraper
- Photos in email templates, where WebP support is still spotty
- Anything a client will download and open on an old machine
PNG stores every pixel exactly as it is. Nothing is thrown away, which makes it the container of record for graphics and screenshots.
Pros
- Lossless through any number of edits
- Real alpha transparency
- Sharp edges stay sharp
Cons
- Heavy on photographs, 5 to 10x JPG
- No quality dial to trade size against
When to use it on a site
- UI screenshots in docs and READMEs, where text must stay sharp
- Logos and icons that need transparency before their final export
- The working master you edit, then convert to WebP to ship
