Frequently Asked Questions

How much can I compress an image?▼
Typically 50–80% smaller depending on the original file and quality setting. Photos compress more than screenshots or graphics with flat colors.
Does compressing an image change its dimensions?▼
No. Compression only reduces the file size. The pixel dimensions (width × height) remain exactly the same.
Which image format compresses best?▼
JPG is best for photographs and complex images. PNG is best for graphics, screenshots, and images with transparent backgrounds. WebP generally achieves the best compression of all.
Is there quality loss when compressing?▼
At quality settings of 80% and above, the quality difference is barely perceptible to the human eye. The quality slider gives you full control.
Are my images uploaded to a server to compress?▼
No. Compression uses the HTML Canvas API entirely in your browser. No data is transmitted.
