JPG vs PNG vs WebP: Which Image Format Should You Use?
Saving an image usually means picking a format from a list without much thought. The choice matters more than it looks: the wrong one gives you a blurry logo or a photo ten times larger than it needs to be.
Key takeaways
- JPG is lossy and best for photographs.
- PNG is lossless and supports transparency.
- WebP offers both modes in smaller files.
- Choose by content: photo, graphic or transparent.
JPG: small files for photos
JPG compresses by discarding detail the eye is unlikely to miss. On photographs, with their soft gradients and natural noise, that works extremely well — files shrink dramatically with no visible change.
It struggles with sharp edges and flat colour, where its compression shows up as fuzzy halos around text and lines. It also cannot store transparency.
PNG: every pixel, exactly
PNG is lossless: what you save is exactly what you get back. That makes it the right choice for screenshots, logos, diagrams and anything with text, and it supports transparent backgrounds.
The price is size. A photograph saved as PNG is often several times larger than the same picture as a good-quality JPG.
WebP: the modern all-rounder
WebP can work in either mode. Its lossy mode competes with JPG at smaller file sizes, and its lossless mode competes with PNG while still supporting transparency. Every modern browser can display it.
The main reason not to use it is compatibility outside the browser: some older apps and upload forms still expect JPG or PNG.
Choosing in practice
For photos, use JPG or lossy WebP. For screenshots, logos and graphics, use PNG or lossless WebP. If you need a transparent background, JPG is out.
The same logic applies when you extract frames from a video: JPG for a large batch of stills, PNG for the few frames you plan to edit. Video to Images can export frames in all three formats, and its Image Compressor reduces the size of images you already have.
