Quick Answers
How do I compress a PNG file?
Upload the PNG and let the optimizer reduce palette depth, filtering, and metadata. Screenshots and graphics often shrink 30–70%.
How do I make a PNG smaller without losing transparency?
Keep the PNG format (or convert to WebP lossless) — both preserve the alpha channel. Converting to JPG would discard transparency entirely.
Why are PNG files bigger than JPG?
PNG stores every pixel losslessly, while JPG discards detail humans barely notice. For photos that makes JPG 5–10× smaller — but PNG is the right choice for text, sharp edges, and transparency.
