About resizing

Drop a WebP and scale it by exact pixels or a percentage, aspect ratio locked, never upscaling by accident — then download the result as WebP, all on your device. WebP is a modern web format that is typically 25–35% smaller than JPG or PNG at the same quality, with transparency, and resizing it here re-encodes at the web-standard quality default so the file stays lean.

Because everything runs in your browser with WebAssembly, there's no upload, no queue and no size cap. It's the same engine as our full image tools, focused on WebP.

Frequently asked questions

Is my WebP uploaded anywhere?
No. It runs entirely in your browser with WebAssembly — your WebP never leaves your device, and there is no size or count limit.
Does resizing change the format?
No — a WebP stays a WebP. It's re-encoded at the PRD-standard quality default, and EXIF orientation is baked in so it always displays upright.
Can I use this on other formats too?
Yes — the main tool handles JPG, PNG, WebP and GIF. This page just starts you on WebP; use the full tool to mix formats.
