About resizing
Drop a JPG and scale it by exact pixels or a percentage, aspect ratio locked, never upscaling by accident — then download the result as JPG, all on your device. JPEG is the universal lossy photo format — small and readable everywhere, but with no 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 JPG.
Frequently asked questions
- Is my JPG uploaded anywhere?
- No. It runs entirely in your browser with WebAssembly — your JPG never leaves your device, and there is no size or count limit.
- Does resizing change the format?
- No — a JPG stays a JPG. 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 JPG; use the full tool to mix formats.
