Why rasterise an SVG, and what "rasterise" means
SVG stores shapes as maths: a circle is a centre, a radius and a stroke. PNG stores a grid of pixels. Converting between them is not a format swap like WebP to PNG — it is a rendering step, and it has to make decisions that SVG never had to make.
The main decision is size. An SVG has no intrinsic resolution; it is sharp at any scale. A PNG does not, so you must choose the pixel dimensions and the rendering resolution at export time. Export too small and it will look soft when displayed larger; export too large and the file is needlessly heavy.
Choosing the export size
Work backwards from how the image will be displayed. If it will sit in a 400-pixel-wide slot on a high-DPI screen, export at 800 pixels. If it is destined for print, aim for 300 DPI at the final printed size — a 2-inch logo needs about 600 pixels.
Things that commonly go wrong
- Text renders with a substitute font when the SVG references a font the renderer does not have — convert text to outlines in the source file if the exact typeface matters.
- Filters, blend modes and masks are the SVG features most likely to render differently or not at all.
- Transparency is preserved by PNG; if you need a solid background you must add it explicitly, or the image will have transparent areas.
- Keep the SVG. The PNG is a frozen, single-resolution copy and cannot be scaled back up cleanly.
常見問題
為什麼要把 SVG 點陣化成 PNG？
PNG 在 SVG 無法使用的場合中也能運作 — 電子郵件用戶端、聊天應用程式和大多數影像編輯器。
PNG 會很大嗎？
SVG 因為是向量圖形，所以通常很小。PNG 版本取決於圖片尺寸，但會保留完整品質。
這是免費的嗎？
是的 — 免費、無限量、無需帳號。
