UI Screenshots
Compress PNG screenshots from design tools and screen captures. Reduce file size for faster loading in documentation, bug reports, and design reviews.
Design Assets

SimpleSteps
Upload Your PNG
Drag and drop or select the PNG file you want to compress. Transparency is fully preserved.
Optimize PNG
Keep PNG output selected. ImgSplit re-encodes the image losslessly and keeps the original file whenever re-encoding would make it larger.
Download Optimized PNG
Save your compressed PNG. Transparency, color depth, and visual quality are maintained.
FAQ
No. The compression process preserves the alpha channel completely. Your transparent backgrounds remain intact.
PNG uses lossless compression which preserves every pixel exactly, plus it stores transparency data. For photos without transparency, converting to JPEG or WebP yields much smaller files.
If you need maximum size reduction and your platform supports WebP, converting to WebP can reduce file size by 50-80% compared to optimized PNG while still supporting transparency.
