Frequently Asked Questions

How much can I compress an image without losing quality?

You can typically reduce file size by 60-80% with minimal visible quality loss using our 'Balanced' or 'High Quality' presets. The exact amount depends on your image - photos compress more than graphics.

What's the difference between JPEG, PNG, and WebP?

JPEG is best for photos with lots of colors. PNG is best for graphics, logos, and images with transparency. WebP is a modern format that typically produces the smallest files with excellent quality - it's ideal for websites.

Is my image uploaded to your servers?

No! This tool works entirely in your browser using the Canvas API. Your images never leave your device, ensuring complete privacy and security.

Will compression reduce image dimensions?

No, compression only reduces file size by removing unnecessary data. The image dimensions (width × height) remain exactly the same. If you need to resize, use our Image Resizer tool.

Can I compress images for email attachments?

Absolutely! Use our tool to reduce file sizes for email attachments. Most email services limit attachment sizes to 10-25MB, and compression can help you fit more images or reduce sending time.

What quality setting should I use?

For most uses, 85% quality (our 'Balanced' preset) offers the best balance of file size and quality. Use 'High Quality' (92%) for professional photography, or 'Small Size' (75%) when file size is more important than perfect quality.
