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

Not all image formats are created equal. Choosing the wrong one means bloated file sizes or blurry photos. Here's when to use each.

Quick Decision Guide

| If you need... | Use | Why | |---------------|-----|-----| | Photos on a website | WebP | Smallest file size, great quality | | Maximum compatibility | JPEG | Works everywhere since 1992 | | Transparency / logos | PNG | Lossless, supports alpha channel | | Screenshots with text | PNG | Text stays crisp | | Next-gen performance | AVIF | Even smaller than WebP | | iPhone photos to share | JPEG | Convert from HEIC first |

Deep Dive: Each Format

JPEG — The Universal Standard

• ✅ Works in every app, browser, and device
• ✅ Great for photographs
• ❌ No transparency support
• ❌ Lossy compression — quality degrades with repeated saves
• 📦 Typical size: 200KB–2MB for a 1080p photo

PNG — Lossless Quality

• ✅ Perfect quality — no compression artifacts
• ✅ Transparency (alpha channel)
• ✅ Best for screenshots, logos, text-heavy images
• ❌ Large file sizes for photos
• 📦 Typical size: 500KB–5MB for a 1080p screenshot

WebP — Modern All-Rounder

• ✅ 25–35% smaller than JPEG at the same quality
• ✅ Supports both lossy and lossless compression
• ✅ Transparency + animation
• ❌ Not supported in some older apps
• 📦 Typical size: 150KB–1.5MB for a 1080p photo

AVIF — The New Contender

• ✅ 50% smaller than JPEG at the same quality
• ✅ HDR support
• ❌ Limited tool support (growing fast)
• 📦 Typical size: 100KB–1MB for a 1080p photo

When to Convert

Need to switch formats? Here's what to use:

• WebP to JPG — when an app doesn't accept WebP
• HEIC to JPG — iPhone photos to universal format
• Image Compressor — any format, reduce file size

Bottom Line

For web: WebP with JPEG fallback. For sharing: JPEG — it just works. For editing: PNG — preserve quality until final export.
