2026-02-17
Not sure whether to save your image as JPG, PNG, or WebP? Each format has its strengths. Here's a simple guide to help you pick the right one every time.
Quick Comparison
| Feature | JPG | PNG | WebP |
|---|---|---|---|
| Best for | Photos | Graphics & screenshots | Web use |
| File size | Small | Large | Smallest |
| Transparency | No | Yes | Yes |
| Quality | Good (some loss) | Perfect (no loss) | Great (with or without loss) |
| Browser support | Universal | Universal | Most modern browsers |
When to Use JPG
JPG is best for photographs and images with many colors.
Use JPG when:
- You're sharing photos from your camera or phone
- You're uploading images to social media
- You need small file sizes
- The image has lots of colors, gradients, or details
- You're emailing photos
JPG works by removing tiny details your eyes can't see, which is why the files are so small. For most photos, you can't tell the difference between a full-quality original and a compressed JPG.
When to Use PNG
PNG is best for graphics, logos, screenshots, and images that need transparency.
Use PNG when:
- Your image has text that needs to stay crisp
- You need a transparent background (like a logo)
- You're saving a screenshot
- The image has sharp edges and solid colors
- Quality is more important than file size
PNG files are larger than JPG because they don't throw away any data. Every pixel is preserved exactly as-is.
When to Use WebP
WebP is best for websites and apps where performance matters.
Use WebP when:
- You're optimizing images for a website
- You want the smallest possible file size
- You need transparency (like PNG) but with smaller files
- You're building a web app or mobile app
WebP was created by Google specifically for the web. It produces files 25–35% smaller than JPG at the same quality, and much smaller than PNG for graphics.
Real-World File Size Comparison
For the same photo at similar quality:

For a logo with transparency:
| Format | File Size |
|---|---|
| JPG | Not possible (no transparency) |
| PNG | 250 KB |
| WebP | 85 KB |
How to Convert Between Formats
If your image is in the wrong format:
- Go to compress-image.pro
- Upload your image
- Choose the output format you want
- Download the converted file
This is especially useful when a website or platform requires a specific format.
Common Mistakes
- Using PNG for photos — the file will be 3–5x larger than necessary with no visible quality improvement
- Using JPG for logos — text and edges will look blurry and there's no transparency support
- Not using WebP for websites — you're leaving free performance gains on the table
- Saving screenshots as JPG — text will look fuzzy. Use PNG instead
Simple Decision Rule
- Photo from a camera? Use JPG
- Screenshot or graphic with text? Use PNG
- For a website? Use WebP
- Need transparency? Use PNG or WebP
- Not sure? Start with JPG — it works well for most things
