  3. Adjust settings (quality/size) if needed.
  4. Download the compressed image.

Best compression tips (big SEO intent)

  • Resize first: reducing dimensions often saves more than lowering quality.
  • Photos: use JPG/WebP with moderate quality.
  • Graphics: PNG for transparency; WebP for smaller files when possible.
  • Avoid re-saving: repeated JPG exports reduce quality.

FAQ: Compress Image

How do I compress an image without losing quality?

Use moderate compression and resize to real usage size. Try UniToolx and preview the result.

JPG vs PNG vs WebP: which should I use?

JPG for photos, PNG for transparency/graphics, WebP for excellent web compression in many cases.

Why is my PNG still huge?

PNG is lossless. Convert to WebP if you want much smaller files and don’t need lossless output.
