Does compressing a PNG image upload my file?
No. VaultIMG compresses PNG images locally in your browser, so your files never leave your device.

Compress PNG Images
Compress PNG images in your browser with Light, Recommended, and Extreme levels, then download smaller files without sending them to a server.
- Files stay on your device.
- Processed locally in your browser.
- No uploads. No storage.
Compress Image reduces supported image file sizes locally in your browser and keeps the original files unchanged.
Compression settings are applied to the selected batch. A single result downloads directly, while multiple results are packaged in a ZIP file.
What you can do
- Process JPG, PNG, WebP, SVG, and GIF inputs supported by the selected route.
- Use format-appropriate compression settings and choose an output filename.
- See the resulting size and percentage reduction before downloading.
Before you start
- Animated GIFs keep their frames, timing, transparency, and loop settings in supported modern browsers.
- SVG files use lossless markup minification, so raster quality levels do not apply.
- WebP re-encoding depends on browser support.
- Some already optimized files may not become smaller and can be returned unchanged.
How it works
- Choose the PNG images you want to compress.
- Pick a compression level: Light, Recommended, or Extreme.
- Download the compressed PNG images, as a ZIP when there is more than one.
Common questions
Will compressing PNG images reduce their quality?
Each level trades size against detail. Light keeps images closest to the original, while Extreme produces the smallest files.
