PNG Compressor
Compress PNG files locally — preserve transparency, no upload, no watermark. Reduce file size 10-50% losslessly, or 80%+ by converting to optimized PNG.
Recommended export settings
Need to compress PNG files? PNG (Portable Network Graphics) is the standard format for images requiring lossless quality and transparency support — screenshots, logos, icons, graphics with text, and UI mockups. Despite being lossless, PNG files are often dramatically oversized because the format doesn't compress as aggressively as JPEG. Phone screenshots, Figma exports, and Photoshop saves can easily hit 1-5 MB for a single image. This PNG compressor re-encodes using the browser's native Canvas API with optimized settings, typically reducing file size 10-50% losslessly while preserving all transparency.
- 1PNG preserves transparency and crisp text — JPEG can't. For screenshots, logos, and graphics, PNG is the right format but file size bloats.
- 2Phone screenshots and Figma exports often hit 1-5 MB. Compression is essential for sharing or embedding in websites.
- 3Local processing avoids uploading design assets and confidential screenshots to third-party servers.
- 4Free, no account, no watermark — compress as many PNGs as you need. The tool runs the Canvas API natively; there's no server cost.
- 5Transparency preservation: PNG output keeps alpha channel intact — essential for logos and UI overlays.
- 6Optional convert-to-JPEG mode: for screenshots without transparency, converting to JPEG q85 yields 80%+ additional reduction.

Who uses this tool
Screenshots

Logos & Icons
Compress brand logos and UI icons while preserving transparency. PNG is the right format for these assets.
Design Assets
Compress Figma and Sketch exports for handoff to developers. Smaller files sync faster and load quicker in design tools.
Web Graphics
Compress website graphics like icons, illustrations, and patterns. Smaller PNGs improve Core Web Vitals and SEO.
Documentation
Compress screenshots embedded in technical docs, wikis, and knowledge bases. Smaller images load faster for readers.
Memes & Graphics
Compress social media graphics with text overlays. PNG preserves text crispness where JPEG would blur it.
Frequently asked questions
Typically 10-50% lossless reduction through optimized re-encoding. Some PNGs (especially those saved with old encoders) can shrink 60-80%. If you're willing to convert to JPEG (for images without transparency), expect 80-95% reduction. The exact ratio depends on content: screenshots with text compress well; photos compress poorly in PNG.
