Frequently Asked Questions
No. All compression happens inside your browser using JavaScript. Your images never leave your device. This is the safest way to compress sensitive or private images.
JPEG/JPG, PNG, and WebP. You can drag and drop any mix of these formats and compress them all at once.
You can upload JPG, PNG, WebP, and GIF files. Output formats are JPG, PNG, and WebP. Note: GIF animation is not preserved — animated GIFs are converted to a static image of the first frame. For PNG files, quality settings don't apply (PNG is lossless); quality only affects JPG and WebP output.
When aspect ratio is locked, changing the width automatically adjusts the height proportionally (and vice versa), so the image is scaled without distortion. For example, a 1200×800 image has an aspect ratio of 3:2. If you change the width to 600px, the height automatically becomes 400px. Unlock the ratio to resize width and height independently, which will stretch or squish the image.
