PNG vs JPG vs WebP

Use PNG for crisp graphics

PNG is a strong choice for screenshots, logos, icons, and images with transparency. It usually keeps sharp edges cleaner than JPG, but file sizes can be larger.

Use JPG for photos

JPG is widely supported and often smaller for photos. It does not support transparency, and repeated saving can reduce quality.

Use WebP for websites

WebP often creates smaller files than PNG or JPG while keeping good quality. It is a useful choice for website images and modern browser workflows.

Lossless and lossy compression

PNG uses lossless compression, so saving it does not introduce JPEG-style blocks or halos. JPEG removes image information to reduce size; the quality setting controls how aggressively it does that. WebP supports both lossy and lossless modes, although the result depends on the encoder used by the browser.

Converting a low-quality JPEG to PNG will not restore missing detail. It only stores the already-compressed pixels in a lossless container, often making the file larger.

Transparency and editing

PNG and WebP can preserve transparent pixels. JPEG cannot, so transparent areas must be replaced with a solid background. For logos and overlays, keep a transparent master file. For repeated editing, avoid resaving JPEG after every change because each lossy save can reduce quality.

Quick decision guide

• Choose PNG for screenshots, diagrams, text-heavy graphics, and transparent assets.
• Choose JPEG for compatible, compact photographs that do not need transparency.
• Choose WebP for modern web delivery when smaller files matter.
• Keep the original or highest-quality master before creating smaller delivery copies.

For resizing and quality controls, use the image compressor.
