Compress PNG online for logos, UI assets, and screenshots with transparency. Lower file weight for faster sites and easier sharing without opening desktop editors.

PNG is lossless—compression reduces file size by optimizing encoding and optionally reducing color depth, not by blurring like JPEG.

Photos are usually smaller as JPEG; PNG fits graphics, logos, and transparency.

100% Client-Side

Your data never leaves your computer.

How to use this tool

Upload your PNG, adjust compression settings, preview the result, and download the optimized file.

Worked example

Example: a 1.4 MB PNG screenshot with alpha channel may compress to under 400 KB for documentation sites.

When to use this

  • Optimizing UI assets and icons for production.
  • Shrinking documentation screenshots.
  • Preparing transparent logos for web.

Common examples

  • 2.8 MB hero JPG at 80% quality WebP → often under 500 KB for blog headers.
  • 4 MB product PNG → JPEG export at 85% for catalog listings when transparency is not needed.
  • Batch of blog images resized to 1200 px wide then compressed → faster LCP on static sites.
  • 1.8 MB team photo → WebP at Balanced for about 200 KB on careers page.
  • Ecommerce PNG with transparency → compress without converting to JPEG when alpha matters.

How it works

Upload a JPG, PNG, WebP, or GIF image, choose a compression level and output format, then compress. The tool may resize very large images and tries multiple quality settings (and WebP plus JPEG in Auto mode) to find a smaller file. Processing runs in your browser—files are not uploaded to a server.

Limitations

Compression is lossy for JPEG output. Very small images or transparent PNGs may not shrink much without visible quality loss.

Privacy and file handling
