About this tool
Uses the browser's <canvas> element with toBlob() to re-encode images. Works for PNG, JPEG, WebP. Quality slider applies to lossy formats (JPEG, WebP); PNG is always lossless. AVIF and HEIC encoding are not consistently supported across browsers; for those, a server-side tool is more reliable.
All processing happens entirely in your browser — no input is sent to our servers.
