How to compress PNG images
- Add your PNG images (up to 50).
- Choose lossless or color reduction.
- Download your compressed PNGs.
PNG is ideal for screenshots, logos, icons and graphics with transparency, but it is often heavy: a single screenshot can exceed 2 MB. That slows down websites, fills up inboxes and gets blocked by some online forms.
Recommended reduces the image to a 256-color palette: for a screenshot, logo or flat-color illustration the result looks the same and is often 2 to 4 times smaller. Smallest file goes down to 128 colors. If you need strictly lossless compression, choose High quality: every pixel is kept and the saving is more modest.
For a photo saved as PNG, the format itself is the problem: choose Save as JPG or WEBP in the options for a much lighter file (WEBP keeps transparency). If a file is already optimized, the original is kept. Your images are deleted automatically after 30 minutes.
Frequently asked questions
Is the transparency kept?
Yes, as long as you keep PNG (or choose WEBP). JPG does not support transparency.
Can I compress a PNG losslessly?
Yes, choose High quality: the image stays exactly the same, with a smaller saving.
Why is my PNG still large?
Photos compress poorly as PNG. Save them as JPG or WEBP, or lower the largest side to 1920 or 1280 px.
How many images can I process?
Up to 50 images at once, up to 300 MB per file.
Is it free and private?
Yes, it is free, no account needed, and files are erased after 30 minutes.
