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

How to Convert Between Formats

If your image is in the wrong format:

  1. Go to compress-image.pro
  2. Upload your image
  3. Choose the output format you want
  4. 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
