Compress a Large PNG

For the multi-megabyte exports: caps the longest edge at 2560px and reduces the palette hard.

  1. Upload the oversized PNG.
  2. It is capped at 2560px and heavily compressed.
  3. Download a far smaller file.

Very large PNGs are usually large for a structural reason: the canvas is enormous, the image is really a photograph, or an export tool wrote it carelessly. This preset attacks the first and third at once — the longest edge is capped at 2560 pixels (still ample for any screen) and the palette is reduced aggressively.

If your image is genuinely photographic, expect better results from WebP.

Frequently asked questions

Why is my PNG tens of megabytes?
Almost always because it is a photograph, a very large canvas, or both. PNG stores photographic detail exactly, and exact is expensive.
Will this crop my image?
No. The aspect ratio is preserved; only the scale changes, and only if the image exceeds 2560px on its longest edge.
Is 2560px enough?
It covers essentially every screen use, including high-density displays. Print work is the exception — keep the original for that.
