PNG files exported directly from design tools — Figma, Illustrator, Photoshop — often carry more data than necessary. A Figma export may include metadata, unused colour profile information, or suboptimal compression settings, resulting in files 30–50% larger than they need to be. Reprocessing the PNG through Canvas strips the excess and produces a leaner file with identical visual output.
Unlike JPEG, PNG compression is lossless: every pixel in the output is an exact copy of the input, so transparency, sharp edges, and text remain crisp at any size. This makes compressed PNG the right format for logos, UI components, icons, and any graphic that needs to scale clearly — wherever you need lossless quality at a smaller file size.
The compression runs entirely in your browser. No file is uploaded to any server. For design assets under client NDA, screenshots containing sensitive information, or any PNG you would rather not pass through a third-party service, this tool compresses locally and keeps everything on your device.
Frequently asked questions
No. PNG is a lossless format — the output is pixel-for-pixel identical to the input regardless of how aggressively it is compressed. What changes is how efficiently the data is encoded, not what the data contains. Sharp edges, text, and transparency are preserved exactly.
It depends heavily on the source. A PNG exported from Figma or Photoshop with default settings can often be reduced by 20–50% by re-encoding through Canvas. Already-optimised PNGs (processed by pngquant or similar tools) will see smaller gains. The before/after sizes shown after processing tell you exactly what was saved.
WebP is the better web format in almost every scenario: it delivers the same visual quality as PNG at 25–35% smaller file sizes, and it fully supports transparency. PNG is the right choice when you need guaranteed compatibility — email clients, legacy CMS platforms, or print workflows that cannot handle WebP. For web delivery, WebP wins.
Yes. PNG transparency (alpha channel) is losslessly preserved through this tool. The compression only affects how the pixel data is stored, not the pixel data itself. Logos with transparent backgrounds, cutout product images, and UI elements with partial transparency all retain their alpha channels exactly.
