PNG files are popular for logos, screenshots, icons, illustrations, interface graphics, and images that require transparent backgrounds. The format preserves image data without the type of lossy compression commonly associated with JPG.
The downside is that PNG files can become large, particularly when screenshots or high-resolution graphics contain a lot of detail. Compressing a PNG can reduce unnecessary file data and make the image easier to store, upload, and use on websites.
How to compress a PNG
- Select the PNG image you want to reduce.
- Let PicSqueezer process the image in your browser.
- Download the compressed PNG.
- Check the resulting file size before uploading or sharing it.
When should you use PNG?
Logos and branding
PNG is useful for logos and graphics where crisp edges and transparent backgrounds matter.
Screenshots
Screenshots containing text, interface elements, and sharp lines often work well as PNG files.
Transparent graphics
PNG supports an alpha channel, making it useful for graphics that need transparent areas.
Icons and illustrations
Simple graphics with solid colors and sharp edges can benefit from PNG's lossless characteristics.
PNG vs JPG: which format should you use?
The right format depends on the image. PNG is usually a better choice for transparent graphics, logos, screenshots, icons, and images where crisp edges are important. JPG is generally better for photographs because it can achieve substantially smaller file sizes.
If your PNG is actually a photograph and file size is the main priority, consider converting it with PNG to JPG. You can also try PNG to WEBP for a modern web-friendly image format.
Need to make the image smaller?
If the PNG dimensions are much larger than you actually need, reducing its width and height can make a major difference to the final file size. Use Resize Image to set exact dimensions.

Frequently asked questions
How do I compress a PNG online?
Select your PNG image with the compressor above. PicSqueezer processes it directly in your browser and generates a smaller PNG that you can download.
Does PNG compression reduce image quality?
PNG is a lossless image format. When the image dimensions and pixel data are preserved, PNG compression can reduce file size without changing the actual pixels. More aggressive size reduction may require changing dimensions or converting to another format.
Does PNG compression preserve transparency?
Yes. PNG transparency can be preserved because the alpha channel is part of the PNG image data.
Why is my PNG still large after compression?
PNG works especially well for graphics, logos, screenshots, icons, and images with large areas of similar colors. Photographs usually contain much more complex visual data and often become significantly smaller when converted to JPG or WEBP.
Should I use PNG or JPG for photos?
JPG is generally more suitable for photographs because it can achieve much smaller file sizes through lossy compression. PNG is usually better for graphics, screenshots, logos, illustrations, and images that need transparency.
Can I compress PNG without losing transparency?
Yes. PicSqueezer keeps PNG transparency intact while processing PNG files in the browser.
Are PNG files uploaded to a server?
No. PicSqueezer processes your PNG locally in your browser instead of uploading the original image to a compression server.
