Image Compressor
Reduce image file size online — free, private, and runs entirely in your browser.
About Image Compressor
Our Image Compressor reduces file sizes of JPG, PNG, and WebP images directly in your browser using the HTML Canvas API. No images are uploaded to any server — everything is processed locally on your device for maximum privacy and speed.
Use the quality slider to balance between file size and visual quality. Most images look great at 70-80% quality while being significantly smaller in file size.
Frequently Asked Questions
Is the image compressor free?
Yes, completely free. No signup, no watermarks, no limits. Compress as many images as you need.
Is my image uploaded to a server?
No. All compression happens in your browser using the HTML Canvas API. Your images never leave your device.
What image formats are supported?
You can compress JPG, PNG, and WebP images. The output will be in JPEG format for maximum compatibility.
How much can I reduce the file size?
Most users see 40-70% file size reduction at 70-80% quality. The exact reduction depends on the original image and the quality setting you choose.
Does compression reduce image quality?
There is a tradeoff between file size and quality. At 80% quality, the visual difference is usually imperceptible. You can adjust the quality slider to find the right balance.
Can I compress multiple images at once?
Currently, the tool compresses one image at a time. Batch compression support is on our roadmap.
