  3. Apply and download your PNG, processed entirely on your device.

About resizing

Drop a PNG and scale it by exact pixels or a percentage, aspect ratio locked, never upscaling by accident — then download the result as PNG, all on your device. PNG is a lossless format with an alpha channel — pixel-perfect for logos, screenshots and line art, 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 PNG.

Frequently asked questions

Is my PNG uploaded anywhere?
No. It runs entirely in your browser with WebAssembly — your PNG never leaves your device, and there is no size or count limit.
Does resizing change the format?
No — a PNG stays a PNG. 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 PNG; use the full tool to mix formats.
