How the result works
Compression reduces storage by simplifying image data. Lower quality settings create smaller files but can introduce blockiness, ringing or lost texture. Resizing very large dimensions can save more space than aggressive compression when the destination only needs a screen-sized image.
- Keep the original before compression
- Resize to the largest dimensions actually needed
- Avoid compressing the same copy repeatedly
Common questions
How do I make an image file smaller?
Choose the image, select a quality level and optional maximum width, then create and download the compressed copy.
Does compression reduce resolution?
Quality compression can retain dimensions, while the optional maximum-width setting also resizes the image.
Which quality setting should I use?
Start around 80–85% for general sharing and compare the result before choosing a lower setting.
