PNG vs JPG vs WEBP: which format should you use?

Updated 2026 · ~6 min read

Picking the right image format affects file size, quality, and whether your image even displays correctly. Here's a practical breakdown of the three formats you'll meet most often, and how to convert between them.

JPG — best for photographs

JPG (or JPEG) uses lossy compression tuned for photographs and other images with smooth color gradients. It produces small files and is supported everywhere, from old browsers to printers. Its weaknesses: it cannot store transparency, and repeated saving degrades quality. Use it for photos and complex images where transparency isn't needed.

PNG — best for graphics and transparency

PNG is lossless, so it preserves every pixel exactly. It supports transparency (an alpha channel), which makes it ideal for logos, icons, screenshots, and graphics with sharp edges or text. The downside is large file sizes for photographs, where PNG offers no advantage over JPG or WEBP.

WEBP — the modern all-rounder

WEBP, developed by Google, supports both lossy and lossless modes and transparency, typically producing files 25–35% smaller than JPG or PNG at similar quality. It is supported by all current browsers. For most websites, WEBP is the best default — the main reason to avoid it is compatibility with very old software.

Quick decision guide

How to convert safely

Converting to a lossy format (JPG/WEBP) discards some data, so always keep your original. Converting a JPG to PNG will not restore lost detail — it just stops further loss. Our format converter handles all three formats, processes everything in your browser, and can convert many files at once into a ZIP.

FAQ

Will converting PNG to JPG reduce quality?

Slightly, because JPG is lossy. For photos the difference is usually invisible; for text or sharp graphics, keep PNG.

Is WEBP safe to use now?

Yes — every major browser has supported it for years. Only extremely old software may struggle.
