FAQ
Image Compressor — frequently asked questions
How do I reduce an image to a specific size in KB?
Set a target size in KB and the compressor searches for the highest quality that fits. Or move the quality slider and watch the live preview.
Which format gives the smallest file?
WebP and JPG give the smallest files for photos. PNG is better for graphics with sharp edges or transparency.
Can I resize the image while compressing it?
Yes. Set a maximum width and the image is scaled down with its aspect ratio kept, which often saves even more space.
Are my photos uploaded or stored anywhere?
No. Image Compressor runs in your browser, so your photos stay on your device and are never sent to our servers or saved anywhere.
Is Image Compressor really free? Do I need to sign up?
Yes, it is completely free. There is no account, signup, watermark or email to hand over; open the page and use it as often as you like.
