Convert SVG to WebP — Free, Fast & Private
Converting an SVG to WebP rasterises it: the drawing instructions are run once, at one size, and frozen into pixels. Everything runs in your browser — nothing is uploaded.
The output size is the SVG's own size
MiniPx renders the SVG at the size the file declares: its width and height, its viewBox when the width is missing, or 1024 × 1024 when the file declares no size at all, which the tool tells you. The Max width setting can only bring it down; it never enlarges. For a bigger WebP, set a larger width and height in the SVG before converting, because a small raster cannot be sharpened afterwards.
Transparency is kept
WebP carries an alpha channel, so an SVG with no background stays transparent. The table below records what each test SVG's background became. For a JPG instead, SVG to JPG fills transparency with white; SVG to PNG keeps it losslessly.
Text becomes pixels
Live text in the SVG is drawn with whatever fonts your browser can use when it renders the file, and the result is fixed into the WebP. Convert text to outlines in your editor first if the lettering must match exactly.
Why rasterise an SVG at all
Many places refuse SVG: social networks, marketplaces, some email clients, presentation software and some print workflows. A WebP is accepted more widely and stays small. Keep the SVG as your master and treat the WebP as an export at one size.
Check the WebP against the SVG before you save
The result card shows the output dimensions, which you should compare with the largest size the image will be shown at. A before and after slider lets you inspect edges and the background.
Support and more WebP routes
WebP displays from Safari 14. The WebP converter lists every WebP direction.

| SVG with no size at all | SVG · vector · 451 B | WebP · 1024 × 1024 px · 4.21 KB | 9.6× larger | Kept transparent |
Measured 2026-10-07 in Chromium 145.0.7632.6 by running this page's converter with its default setting (WebP) on each file. The SVGs are small hand-written files, each declaring its size a different way. Sizes are shown as the tool shows them (1 KB = 1,024 bytes).
