About Batch Image Compression
Batch compress images online free
Drop up to 25 JPG, PNG or WebP files and piczen compresses them all at once in your browser. Files are processed locally, never uploaded. Download individually or as a ZIP.
Compress without losing quality
Set quality to 80–85% and piczen shrinks JPG, PNG and WebP files 60–80% with no visible loss. Smart lossless compression is used for PNG and WebP when possible.

Need files under 100KB, 200KB or 500KB for a form or upload portal? piczen lets you set a target size and adjusts quality automatically to hit the limit.
No upload, no watermark
piczen runs entirely in your browser. Your images never leave your device, and the output is clean — no watermark, no logo, no metadata added. GDPR-friendly.
