Frequently Asked Questions about Image Compressor

How does browser-side image compression work?

The browser decodes the image data onto an off-screen canvas and re-encodes it using lossy or lossless compression codecs with optimized quantization tables.

Can I compress images for job or exam applications?

Yes! If an application portal requires images under 50KB or 100KB, adjust the quality slider until the compressed size meets the requirement.

Are there any hidden watermarks added to compressed files?

Never. ToolsCluster never alters your image content or attaches watermarks.
