Resize a PNG to slim it down - perfect for shrinking 4K screenshots before sharing, with transparency preserved.
PNG is lossless, which means you can't compress its pixels - they're already as compact as PNG allows. But PNGs from 4K monitors or modern phones are huge: 5-15 MB for a single screenshot is normal. The fix is to resize: dropping a 4K screenshot to 1920px wide can shrink it by 75% with no visible loss at typical viewing sizes.
We decode your PNG, resize to the max-dimension cap you pick (default 2048px), and re-encode losslessly. Transparency is preserved bit-perfectly. The output is still a PNG, so you can compress it again later without further loss. For maximum size reduction (50-70% smaller), pair this with the JPG converter - PNG-to-JPG sacrifices transparency but produces dramatically smaller files.
PNG is a lossless image format with alpha-channel transparency. Larger than JPG for photos, but ideal for screenshots, logos, and graphics with sharp edges.
