About Image compression
Compression is the most requested image job: upload forms cap file size, pages have to load fast, and email attachments cannot hold large photos. Every tdd8.cn compressor runs locally in your browser—images are never uploaded, so it is private and instant. Drop in up to 300 images at once and download the results individually or as a single ZIP.
FAQ
Does compression lose quality?
It depends on the mode: quality-based compression only does gentle lossy optimization with almost no visible difference; compressing to a target KB lowers quality first, then resolution—size first.
Are my images uploaded to a server?
No. Compression runs locally in your browser; images never leave your device.
How many images at once?
You can drop up to 300 images for batch processing; download each one or pack them all into a ZIP.
