A plain-English guide to picking the right image format. When JPG wins, when PNG is a must, and why WebP is often the best of both worlds.

JPG vs PNG vs WebP: Which Image Format Should You Use?

JPG, PNG or WebP? The choice looks technical, but it comes down to three questions: does your image have transparency, does it have sharp text, and who is going to see it. Here's how to decide in 30 seconds.

Quick decision table

Photos without transparency → JPG or WebP (WebP = same quality, ~30% smaller)
Logos, icons, screenshots, text → PNG or WebP
Anything needing transparency → PNG or WebP
A website you control → WebP, always
Email attachments / old software → JPG

JPG: small photos, photographic images

JPG compresses by discarding details the eye barely notices. That's why it's great for photographs but terrible for screenshots, text and logos — thin lines get muddy and edges fray.

Best for: photos, scans, artwork with smooth gradients
Avoid for: text, diagrams, logos, transparency
Identical quality at 85% — no reason to save at 100%

PNG: pixel-perfect with transparency

PNG is lossless: the image you save is the image you get, edge for edge. It also supports true transparency. The price is file size — 3-6× bigger than JPG on photos.

Best for: logos, icons, screenshots, interfaces, transparent cutouts
Avoid for: large photos where no one will zoom in
Use PNG to JPG when a photo is needlessly a PNG

WebP: the modern winner

WebP combines JPG's small size with PNG's transparency, typically 25-35% smaller than JPG at equal quality. Every modern browser supports it. For websites it's almost always the right choice.

Best for: websites, app assets, anything on screens
Avoid for: legacy software that only accepts JPG/PNG

Practical rules that save time

Save photos as JPG at 80-85% — visually identical, half the size of 100%.
Keep PNG only for transparency or pixel-perfect graphics.
Serve WebP on sites; fall back to JPG/PNG only for ancient clients.
Resize before you export: a 6000px image wastes bandwidth and hurts SEO. Start with Resize Image, then convert and compress.

The quick takeaway: the file format matters less than resizing to the size people actually see. A 1200px WebP at 75% quality loads lightning fast and looks perfect on every screen.
