How to compress images without ruining quality

Image compression is a balance between file size, visual quality, and compatibility. The right choice depends on what the image contains and where it will be used.

Choose the right format

JPEG is usually a good choice for photos because it can reduce file size aggressively. PNG is better for screenshots, diagrams, logos, and images that need transparency. WebP often produces smaller web images, but it may not be accepted by every form or older workflow.

Use the right compression mode

• Balanced works well for most everyday images.
• Smallest file is useful when an upload limit is strict.
• Best quality keeps more detail but may produce a larger file.

Keep original format when unsure

Compressly keeps the original image format by default. This helps avoid surprises when a website expects a JPG, PNG, or WebP file. You can still choose a different output format when you know what you need.

Check the result before sharing

Always open the compressed image before sending or uploading it. Look at faces, small text, transparent areas, and important details. A very small file is not useful if the content becomes hard to read.
