HOW IT WORKS

Private, browser-first processing.

The compressor can reduce JPEG or WebP quality and optionally scale large images down. PNG has no browser quality slider, so choosing WebP is often more effective when file size matters.

The original file remains untouched. ImageShaper creates a new downloadable copy.

PRACTICAL LIMITS

Built for ordinary web images.

  • Inputs are capped at 40 MB.
  • Very large megapixel counts can use substantial browser memory.
  • Quality controls apply to JPEG and WebP outputs.
  • Keep the page open until the output is ready.
FAQ

Before you process.

Will this upload my image?

No. The compressor reads and encodes the selected image in your browser.

Which output format is smallest?

WebP is often a good choice for web use. JPEG can be efficient for photos, while PNG is best when you need lossless pixels or full transparency.

Does compression reduce dimensions?

Only if you choose a maximum width smaller than the source image.
