Pick the ceiling and the compressor works down to it automatically. Lossless PNG optimiser Lossless only Strip the waste, keep every single pixel. The safe option when the image must not change at all. PNG to JPG PNG → JPG For photographs, changing format beats any amount of PNG compression — often by 10×. Resize PNG Resize Cap the longest edge at 1920px. The fastest way to cut size when the image is simply bigger than it needs to be.

compresspng.net makes PNG files small. Drop one in and the palette-based compressor typically takes 60–80% off a screenshot, logo or diagram with no visible change — or switch to lossless mode when not a single pixel may move.

If you are fighting an upload limit, name the target size and the tool works down to it. If the file is really a photograph in the wrong format, convert it to JPEG and watch it collapse. Everything here is free, with no watermark and no account.

Pick the right tool for your PNG

Use the main compressor for everyday shrinking, lossless when the image must not change at all, compress to a size when a form is rejecting your file, and resize when the image is simply larger than it is displayed. Photographs almost always want PNG to JPG instead.

Honest expectations

No compressor can shrink every PNG. Files that were already optimised have nothing left to remove, and a photographic PNG will never reach JPEG sizes while staying a PNG. Where this tool does shine is the ordinary case: screenshots, exports from design tools, logos, icons, charts and UI captures, where 60–80% comes off without anyone being able to tell.

Frequently asked questions

How do I compress a PNG file?
Upload it to the compressor on this page and download the result. Choose Lossless if the image must stay pixel-identical, or leave it on Balanced for the best size-to-quality trade-off.
How much can a PNG compress?
Graphics and screenshots typically drop 60–80%. Lossless mode manages 5–15%. Photographs stored as PNG compress poorly by comparison and should be converted to JPEG.
Can I compress PNG files without losing quality?
Yes — the lossless optimiser keeps every pixel and the whole alpha channel. It removes only redundant file data.
Do you keep my images?
Files are processed in an isolated workspace and deleted automatically a short time after your download.
Is there a watermark or a signup?
Neither. Every tool on the site is free to use with no account.
