Compress PNG Online — Shrink PNG Files Without Losing Transparency

PNG files are often 3–10× larger than equivalent JPEGs because they use lossless compression. Our PNG compressor reduces file size using color-depth optimization and metadata stripping — keeping transparency intact for logos, UI assets, and illustrations.

How It Works

  1. 1

    Upload your PNG

    Drag a PNG file onto the uploader. Transparent PNGs (with alpha channel) are fully supported and transparency is preserved throughout.

  2. 2

    Adjust compression settings

    Choose between lossless compression (removes metadata, reduces color depth) or lossy compression (significant size reduction with minimal visual impact).

  3. 3

    Download the optimized PNG

    Save the compressed file. Transparent regions remain fully transparent — safe to use in Figma, Canva, or web designs.

Frequently Asked Questions

Will compressing a PNG remove the transparent background?+
No. The tool preserves the PNG alpha channel, so transparent backgrounds remain transparent after compression. The output is always a valid PNG with identical transparency.
Should I use PNG or JPEG for website images?+
Use PNG for logos, icons, and graphics with transparency. Use JPEG for photos. Compressing either format before uploading to your site significantly improves page load speed.
How much can I reduce a PNG file?+
Lossless compression typically reduces PNG size by 20–40%. With lossy optimization (converting to 8-bit color palette), reductions of 60–70% are achievable with minimal visible impact.
