PNG is ideal for crisp graphics and transparent backgrounds, but PNG files can become heavy when screenshots or detailed artwork include lots of colors. Compressing PNG helps reduce file weight while keeping the same practical format.
Reduce heavy screenshots
Screenshots and UI captures can often be optimized before sharing or publishing.
Stay design-tool friendly
Compressed PNG files remain easy to use in documents, websites, and design tools.
PNG compression guide
Compression results depend on image content, transparency, animation, and how the format stores detail.
| Detail | PNG |
|---|---|
| Compression type | Lossless mode or palette reduction in Balanced and Smallest file |
| Transparency | Supports full alpha transparency |
| Best use case | Transparent images, screenshots, UI captures, icons, and sharp graphics |
| Watch for | Photo-heavy PNG files can remain larger than JPG or WebP after compression. |
| Expected savings | Best savings usually come from removing metadata and optimizing color/pixel data. |
What happens to your file?
Upload your PNG image, let the compressor create a smaller PNG file, then download the optimized result. Files are processed for compression, stored temporarily for download, and automatically deleted after 24 hours.
Compress PNG FAQ
Will compressing PNG remove transparency?
No. PNG supports alpha transparency, and compression keeps transparent backgrounds when they exist in the source file.
Will PNG compression reduce image quality?
Balanced and Smallest file can reduce colors and change pixels. Choose Lossless to preserve decoded pixels and dimensions; TinyImage keeps the original if a smaller exact rewrite is unavailable.
Why is my compressed PNG still large?
PNG can remain large for photos, smooth color transitions, and detailed screenshots. JPG or WebP may be smaller for photo-style images.
Can I compress multiple PNG files at once?
Yes. You can upload up to 20 PNG images and download optimized files after processing.
How long are compressed PNG files stored?
Files are processed for compression, stored temporarily for download, and automatically deleted after 24 hours.
