Compress PNG — Reduce File Size for Web & Uploads
Screenshots, logos, and graphics with transparency are often too large for form uploads or web pages. Compress your PNG to any size limit — preview first, then download. Transparency is preserved.
Set the file size limit your upload form or website requires.
Target: 500.0 KB (500 KB)
Increase if the file is still too large. Decrease to preserve more detail. PNG stays lossless until resizing is needed.

Frequently asked questions
How is PNG compression different from JPEG?
PNG uses lossless compression — pixels stay sharp and transparency is preserved. JPEG uses lossy compression, which produces smaller photos but removes transparency. Use this tool when you need to keep PNG format.
Will my PNG lose quality?
Optimization is lossless, so colors and edges stay crisp. If the file is still too large after optimization, the tool may reduce dimensions to meet your target — check the preview before downloading.
Does this preserve transparent backgrounds?
Yes. Logos, icons, and screenshots with transparency keep their transparent areas. The output is always PNG.
Can I upload JPEG or WEBP files?
Yes. Non-PNG images are converted to optimized PNG on output. This is useful when a form specifically requires PNG format.
Is my image uploaded to a server?
No. Everything runs in your browser. Your screenshots and graphics never leave your device.
