JPG vs PNG: Complete Comparison
Choosing between JPEG and PNG is one of the most common decisions in web design and photography. Here's everything you need to know to pick the right format.
Use JPG when…
- You're sharing photographs
- File size matters (email, web)
- No transparency needed
- Colors are complex & gradients exist
- Uploading to social media
Use PNG when…
- You need transparent backgrounds
- Saving logos or graphics
- Image will be re-edited later
- Text or sharp edges are present
- Lossless quality is required
Side-by-Side Comparison
| Feature | JPG / JPEG | PNG |
|---|---|---|
| Compression | Lossy (smaller files) | Lossless (larger files) |
| Transparency | ❌ Not supported | ✅ Full alpha channel |
| Best for | Photographs & complex colors | Logos, screenshots, graphics |
| File size | Very small (40–80% smaller) | Large (especially for photos) |
| Animation | ❌ Not supported | ❌ Not supported (use GIF/WEBP) |
| Color depth | Up to 24-bit | Up to 48-bit (true color) |
| Progressive loading | ✅ Progressive JPEG | ✅ Interlaced PNG |
| Browser support | ✅ Universal | ✅ Universal |
| Print quality | Good | Excellent (lossless) |
| Multiple saves | Degrades each re-save | No degradation |
What is JPG/JPEG?
JPEG (Joint Photographic Experts Group) is the most widely used image format for photographs and complex imagery. It uses lossy compression, meaning some image data is discarded during compression. This results in dramatically smaller file sizes — often 5–10x smaller than PNG for the same photo. JPEG works by reducing detail in areas the human eye is least sensitive to, making the quality loss often imperceptible.
What is PNG?
PNG (Portable Network Graphics) uses lossless compression, preserving every single pixel. This makes it ideal for graphics, logos, screenshots, and images with transparent backgrounds. PNG files are significantly larger than JPEG for photographs, but the quality is perfect — no artifacts, no compression damage. PNG also supports partial transparency (alpha channel), which JPEG cannot.
The Modern Alternative: WEBP
In most cases, WEBP is now the best choice for web images. It offers 25–35% smaller file sizes than JPEG while supporting transparency like PNG. All modern browsers support WEBP. Convert your images using our free tool below.
