PNG vs JPG: Which Is Better?
PNG and JPG solve different problems. PNG is lossless and supports transparency. JPG is smaller and ideal for photos. Use the comparison below to pick the right format.
Key Dimensions and Reference Table
Use the reference table below as your starting point. These values are designed to fit common platform requirements and prevent cropping or unexpected compression. When possible, export at the exact dimensions for maximum clarity.
If you are unsure about format choice, default to JPEG or WebP for photos and PNG for text-heavy graphics. The right format keeps files lightweight without blurring edges or flattening gradients. When a platform supports modern formats, WebP is usually the fastest option.
A reliable workflow is to resize from the original high-resolution file, export once at the target size, and then upload. Repeated resizing or re-compressing the same file compounds artifacts and reduces clarity over time.
| Attribute | PNG | JPG | Best Use |
|---|---|---|---|
| Compression | Lossless | Lossy | PNG for graphics, JPG for photos |
| Transparency | Yes | No | PNG for overlays and logos |
| File size | Larger | Smaller | JPG for web performance |
| Text clarity | Excellent | Good | PNG for sharp text |
When PNG Wins
Use PNG when you need crisp edges, transparency, or repeated edits. It preserves exact pixels, which makes it ideal for logos and UI assets.
PNG is also better when your image includes text or line art, since compression artifacts are more obvious on sharp edges.
When JPG Wins
Use JPG for photographs and complex gradients. The smaller file sizes improve load times and reduce bandwidth costs.
Adjust quality between 80-90% to balance detail and file size.
How to Choose
Ask whether transparency is required. If yes, use PNG. If not, evaluate whether file size or pixel perfection matters more.
You can also compare output formats in PixelPerfect Resizer by exporting both versions.
Quality and Compression Tips
Start with the highest-quality source image, resize to the final dimensions, and then adjust compression. This keeps edges clean and prevents the muddy look that happens when files are compressed repeatedly. If your image contains text, use PNG or a high-quality JPEG to keep characters sharp.
For photos, WebP or JPEG at 80-90% quality is usually the best balance of size and clarity. For graphics or logos, use lossless PNG. Always preview the final export at 100% before uploading.
- Resize first, compress second.
- Match the target aspect ratio to avoid cropping.
- Export once to prevent cumulative artifacts.
- Use sRGB color for consistent display across devices.
Practical Examples
A product hero photo on an ecommerce site should use JPG or WebP at a reasonable quality. A brand logo with transparency should use PNG to keep edges sharp.
Common Mistakes
- Using PNG for large photos and slowing down pages.
- Using JPG for icons and getting fuzzy edges.
- Over-compressing JPG and creating artifacts.
