JPG vs PNG: Which Format Should You Use?
The definitive guide to choosing the right image format for photos, websites, logos, and apps.
⚡ Quick Answer
JPG = Photos and complex images. PNG = Logos, icons, screenshots, and anything with transparency.
JPG uses lossy compression (smaller file, slight quality loss). PNG uses lossless compression (larger file, perfect quality). For websites, use JPG for photos and PNG for graphics.
The Core Difference: Lossy vs Lossless
The fundamental difference between JPG and PNG is their compression method:
- JPG (Lossy): Permanently discards some pixel data to achieve smaller files. The quality loss is usually invisible in photos but very noticeable in text, logos, and flat-color graphics.
- PNG (Lossless): Compresses data without discarding any pixels. Every pixel is preserved perfectly. Results in larger files but perfect quality — critical for logos and screenshots.
Quick Reference Comparison
| Feature | JPG / JPEG | PNG |
|---|---|---|
| Compression | Lossy | Lossless |
| File Size | Smaller | Larger |
| Transparency | Not supported | Full alpha support |
| Best For | Photos, backgrounds | Logos, icons, screenshots |
| Quality Loss | Yes (slight blurring) | None |
| Web Performance | Better (faster load) | Acceptable |
When to Use JPG
- Photographs (portraits, landscapes, product shots)
- Website hero images and banners
- Social media posts with photos
- Any image where file size matters more than perfect sharpness
When to Use PNG
- Logos and brand assets (especially on varied backgrounds)
- Icons and UI elements
- Screenshots with text (JPG blurs text edges)
- Anything needing a transparent background
- Diagrams, charts, and infographics
What About WebP and AVIF?
Modern formats like WebP and AVIF offer both lossy and lossless compression — achieving 25–50% smaller files than JPG or PNG at equivalent quality. If you're building a website in 2026, converting images to WebP is a significant page speed win. Most modern browsers support it. OrangeTool's image compressor supports WebP output for this purpose.
Frequently Asked Questions
Should I use JPG or PNG for my website?
Use JPG for photographs to keep file sizes small and load times fast. Use PNG for logos, icons, and anything needing transparency. Better yet, convert all to WebP for best results.
Does converting PNG to JPG reduce quality?
Yes. JPG uses lossy compression which permanently discards some pixel data. Text and sharp edges will appear slightly blurred. This conversion is irreversible — keep your original PNG.
Which is better for SEO — JPG or PNG?
JPG is generally better for page speed SEO because its file sizes are smaller. But for logos and quality-critical images, PNG is correct. Always compress images before uploading regardless of format.
