About the Compress PNG Tool
PNG files can become massive due to their lossless nature. Our PNG compressor intelligently reduces the color palette and strips unnecessary metadata, resulting in massive file size savings (often 70% or more) while remaining virtually identical to the naked eye.
100% Private — Processed in Your Browser
Every file stays on your device. DCPIXEL processes images entirely using the browser's built-in Canvas API and WebAssembly — zero server uploads, zero data collection.

Frequently Asked Questions
How much can I compress an image without losing visible quality?+
For JPG and WebP, reducing to 70-80% quality typically produces a file 60-80% smaller with no perceivable quality loss on screens. PNG uses lossless compression that preserves every pixel.
What is the difference between lossy and lossless compression?+
Lossy compression (JPG, WebP) permanently removes some image data to achieve smaller files. Lossless compression (PNG) reorganizes data without any quality loss. For photos, lossy is usually fine; for logos with text, use lossless.
Can I compress multiple images at once?+
Currently you compress one image at a time to give you full control over quality preview. The entire process takes under 5 seconds per image.
Will compressing an image change its dimensions or format?+
No. Compression only reduces file size. The output image has the same pixel dimensions and format as the original.
