How to compress a PNG in 3 steps

Drop your PNG files into the box above, or click to browse. Riducly compresses each one instantly in your browser. Then download the optimized PNGs one by one, or all at once as a ZIP.

Lossless vs lossy PNG compression

PNG supports lossless compression, which rebuilds the exact same pixels at a smaller size — ideal for logos, icons and screenshots. For photos with many colors, a lossy pass (or converting to WebP) drops invisible detail to save far more space. Riducly lets you keep the PNG format or switch to a lighter one.

Why PNG files are so heavy

PNG stores every pixel without throwing data away and keeps a full alpha (transparency) channel. That makes it perfect for sharp edges and transparent backgrounds, but it also means uncompressed exports — especially from design tools — can be several megabytes. Compression trims that overhead while keeping the image identical to the eye.

PNG or WebP? When to convert

Keep PNG when you need transparency or pixel-perfect graphics with broad browser and email support. Switch to WebP when you want the smallest possible file for the web and don't need legacy compatibility. Riducly can do both from the same tool.

Frequently asked questions

Does compressing a PNG reduce its quality?
Lossless PNG compression keeps the image pixel-for-pixel identical while removing redundant data. If you choose a stronger setting or convert to a lossy format, the change is tuned to stay invisible at normal viewing size.
Are my files uploaded to a server?
No. Riducly compresses images entirely in your browser, using your device's own processor. Your files never leave your computer, which keeps the tool private and fast.
What's the difference between PNG and JPG?
PNG is lossless and supports transparency, so it's best for logos, icons and screenshots. JPG is lossy and has no transparency, which makes it better for photographs where a smaller file matters more than perfect edges.
Can I compress transparent PNGs?
Yes. Riducly preserves the alpha (transparency) channel, so PNGs with transparent backgrounds stay transparent after compression.
Is there a limit to how many PNGs I can compress?
You can compress multiple files at once for free. Creating a free account unlocks higher limits and parallel, multi-core compression for larger batches.
