Output Formats - PNG, JPEG, WebP, and PDF

Output formatsOutput Formats

The right format depends on where the image is going. A transparent overlay wants PNG. A photo-heavy social card is smaller as JPEG. The web loves WebP. A certificate wants to print. One parameter now covers all four.

• png - lossless with transparency, best for logos, overlays, and crisp edges.
• jpeg - smallest for photographic designs; add ?quality= (1-100) to trade size against fidelity.
• webp - modern web format with a strong size-to-quality ratio.
• pdf - a single-page document, ideal for certificates, tickets, and anything headed to a printer.

?quality= only applies to JPEG. Lower it for thumbnails and previews where bytes matter more than pixels, leave it high for anything customer-facing:
