WebP vs JPG vs PNG: Which Format Should You Export?

The “best” image format depends on content type (photo vs flat graphic), whether you need transparency, and what your audience’s browsers support. For most marketing sites in 2026, WebP or well-tuned JPEG covers the majority of photo cases; PNG remains the safe choice for sharp UI and logos with alpha.

Quick decision guide

• Photos / gradients → JPEG or WebP (smaller than PNG at similar visual quality).
• Logos, icons, screenshots with text → PNG (or WebP lossless / high quality if you control the stack).
• Need transparency → PNG or WebP (JPEG has no alpha).
• Maximum compatibility with ancient clients → JPEG for photos, PNG for graphics.

JPG (JPEG)

JPEG is still the universal photo format. It handles continuous-tone images well and is accepted almost everywhere (email, CMSs, social uploads). Weaknesses: no transparency, and heavy compression introduces blocky artifacts—especially around text and hard edges.

PNG

PNG is lossless for typical web use and supports transparency. It is excellent for UI chrome and diagrams. For large photos it is usually much heavier than JPEG/WebP at a similar look, so prefer PNG when sharpness and alpha matter more than bytes.

WebP

WebP often beats JPEG on size for the same perceptual quality and can include transparency. Modern browsers support it widely. Prefer WebP when you control the site and can keep a JPEG/PNG fallback only if analytics show a real need.

Exporting with a target size

In Upload‑Ready, pick the output format after you set a target file size. If a CMS still rejects WebP, export JPEG at the same byte budget. For a deeper look at newer codecs, see our AVIF vs WebP note.
