No. Compression happens entirely in your browser; your images never leave your device.
Which image formats can I use?
Input JPG, PNG, WebP and GIF; export as JPEG, WebP or PNG.
Can I compress to a specific file size?
Yes. Set a target size in KB and CRUSH finds the quality to hit it, or switch to manual quality control.
Can I resize and crop as well?
Yes. Resize by width/height with optional aspect lock, and crop with preset or free aspect ratios.
Can I compress several images at once?
Yes. Add a batch of images and download them all together.
How do I compress an image to under 1 MB?
Set the target size field to 1000 KB. CRUSH will automatically find the right quality level to hit that size.
Does compressing an image reduce its quality?
Yes, but CRUSH lets you control how much. Use the target-size mode to balance file size and quality, or use the quality slider for full control. WebP typically looks better than JPG at the same file size.
What is the difference between WebP and JPG?
WebP is a modern format that achieves roughly 25–35% smaller file sizes than JPG at the same visual quality. It is supported by all modern browsers.
Can I resize an image online for free?
Yes. CRUSH includes a free resize tool — set a target width or height, lock the aspect ratio if you want, and download the resized image instantly.
