Frequently Asked Questions
How do I compress an image?
Upload your image (or drop in several at once), choose an output format, and adjust the quality slider. Each one compresses on its own and updates instantly. Click Download to save.
Can I compress multiple images at once?
Yes. Drop in as many images as you like - each compresses independently with the same quality setting, and you can download them all together as a ZIP.
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 images never leave 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.
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.
