PNG vs JPG vs WebP: Which Image Format Should You Use?

Quick comparison

JPEG (JPG) is best for photographs and complex images without transparency — smallest files for photos, no alpha channel.

PNG is best for logos, icons, screenshots with sharp text, and any image that needs a transparent background — larger files than JPEG for photos.

WebP is best for the modern web when you control delivery — often 25–35% smaller than JPEG at similar quality, supports lossy, lossless, and transparency, and is supported by all major current browsers.

When to use JPEG

Use JPEG for camera photos, product shots, and hero images where you do not need transparency. It is the default for “real world” photos because lossy compression throws away detail humans rarely notice.

After export, run a compressor if the CMS or email still complains about file size — our image compressor works in the browser without uploading your files.

When to use PNG

Use PNG when you need crisp edges, text overlays, UI captures, or transparency (logos on variable backgrounds). PNG is lossless for typical exports, so file sizes grow quickly for large photos — avoid PNG for huge photographic banners unless you need transparency.

When to use WebP

Use WebP for site performance: same-looking images with smaller downloads improve Core Web Vitals and user experience on mobile.

Convert JPG sources with our JPG to WebP tool; for PNGs with transparency, prefer WebP over JPEG when you need to keep alpha. Pair with resizing so you are not serving oversized dimensions.

Workflow tip

Start from the highest-quality master, resize to the display size you need, then compress or convert format. That order avoids double lossy compression and keeps text and edges as sharp as possible.
