PNG is always lossless. File size reduction comes from dimension changes and metadata stripping.
Keep PNG to preserve transparency. WebP supports transparency too and is 25-35% smaller.
PNG Compression FAQ
No. PNG uses lossless compression, which means no image data is ever discarded. Every pixel stays exactly the same. File size reduction comes from removing metadata (EXIF) and optionally reducing dimensions — not from throwing away visual information.
Yes, as long as you keep PNG as the output format. If you switch to WebP, transparency is also preserved — WebP supports alpha channels just like PNG, but with much smaller file sizes. A green "Transparency preserved" badge appears when your image has an alpha channel.
PNG is a lossless format, so it cannot compress photos as aggressively as JPEG or WebP. If your PNG is a photograph, try converting to WebP for 60-80% smaller files. For screenshots, logos, and graphics with sharp edges, PNG is the right choice — try resizing dimensions for further reduction.
Use PNG for images with transparency that need to work everywhere (older email clients, some design tools). Use WebP for websites — it supports transparency, offers 25-35% better compression, and is supported by 96%+ of browsers. Our tool lets you switch formats with one click.
