Upload up to 24 images and resize them all in one go. A real time saver for batch workflows.
Resize PNG images while keeping full transparency
PNG is lossless with a real alpha channel — the go-to format for logos, UI exports, screenshots, and graphics with text. Our PNG resizer keeps the container and the color type (indexed, grayscale, RGB or RGBA) exactly as uploaded.
When to resize a PNG
Exports from Figma or Sketch at 2x/3x often need a 1x version. 4K screenshots have to drop to 1920 px for documentation. A 1024 px app icon needs 512, 256, 192, 180, 152, 120, 96, 72, 48 and 32 for a full iOS/Android/PWA bundle.
How transparency and sharp edges are preserved
The alpha channel is carried through the full pipeline, so transparent backgrounds stay transparent. Indexed-color PNGs are kept as palette PNGs instead of being forced into full RGBA.
Batch resize up to 24 PNG files at once
Drop up to 24 PNG files (up to 10 MB each), apply the same dimensions to the whole batch, and download a single ZIP. Files are kept 24 hours, then deleted automatically.
