Compress PNG

Shrink PNG file size for free. Your files never leave your browser.

Make your PNG images smaller while keeping them looking sharp. This free compressor reduces PNG file size by reducing the number of colours — the same technique used by tools like TinyPNG, so your images load faster and take up less space.

How to compress PNG

  1. Add your PNG file. Drag and drop your PNG file onto the box, or click to browse.
  2. Pick a compression level. Compress is already on — choose Low, Medium, or High to balance size and quality.
  3. Download. Click Convert and your PNG file downloads automatically.

Compression tips

Choose a compression level to balance size against quality. Low keeps the most detail, High makes the smallest file. PNG compression here is lossy, so preview the result before using it for critical work.

Is it private?

Your PNG files are converted entirely inside your browser. Nothing is uploaded to a server, so your images stay completely private — and conversion is instant, even offline.

Frequently asked questions

Is this PNG compressor free?

Yes — it is completely free with no limits, no account, and no watermark.

Are my files uploaded?

No. PNG conversions run entirely in your browser, so your files are never uploaded.

Will compressing reduce quality?

Some quality is traded for size. Use the Low setting to keep the most detail, or High for the smallest file.

Does it work on mobile?

Yes — it runs in any modern browser on phone, tablet, or desktop.
