Frequently Asked Questions
How do I compress an image?
Upload your image, choose an output format, and adjust the quality slider. The compressed preview and file size update instantly. Click Download to save.
How much can I compress an image?
For JPG and WebP, you can go from 1% to 100% quality. At 60-80%, most images lose little visible quality while reducing file size significantly.
Is my image uploaded to a server?
No. All compression happens in your browser using the Canvas API. Your image never leaves your device.
What formats are supported?
You can compress and export as JPG, WebP, or PNG. JPG and WebP support quality adjustment; PNG uses lossless compression.
Which quality setting should I use?
For web use, 60-80% is usually ideal. For print or archiving, use 90%+. The Balanced (80%) preset is a good starting point.
Will the image dimensions change?
No. Compression only affects file size and quality, not the width or height of the image. Use the Image Resizer if you need to change dimensions.
