Why PNG files are often larger than JPG
PNG uses lossless compression, so every pixel is preserved exactly — great for sharp edges and transparency, but it means file size stays high for anything with a lot of detail or gradients.

Compress PNG online without losing transparency
PNG files can be much larger than they need to be, especially for screenshots and exports from design tools. This page shows how to shrink a PNG while keeping its transparent background intact.

Shrink the PNG, keep the transparency
How to shrink a PNG and keep transparency
Add your PNG, adjust the quality setting, and check the preview to confirm transparent areas still look correct — then export. The alpha channel travels through the process unchanged.
What is the difference between compressing a JPG and a PNG?
JPG has no transparency and uses a quality slider that removes detail to save space. PNG keeps every pixel and any transparency, so its size reductions tend to be smaller but the image stays pixel-exact.
FAQ
Compress PNG online FAQ
What is the difference between compressing a JPG and a PNG?
PNG compression preserves every pixel, including transparency, so size reductions are usually more modest than JPG. If transparency does not matter, converting to JPG can shrink the file much further.
Will compressing my image remove the EXIF or location data?
PNG files typically carry little or no EXIF data to begin with, but if your PNG came from a tool that embeds metadata, Strip Metadata can clear it explicitly.
Can I compress multiple images at once?
Yes — select a batch of PNGs, such as a set of exported icons or screenshots, and compress them together with the same settings.
Does compressing an image change its dimensions?
No — width and height stay exactly the same. If the PNG also needs to be smaller in pixels, use Resize before or after compressing.
