Compress Image to 1MB

The tool searches for the highest quality it can keep while aiming for 1MB.

Quality is reduced first. Pixel dimensions are reduced only when needed to approach the exact byte target.
HOW IT WORKS

Private, browser-first processing.

ImageShaper reads and processes selected files directly in your browser. The source image is not uploaded to a conversion server by the tool.

For very large images, browser memory limits vary by phone or computer. Keep the tab open until processing finishes.

PRACTICAL LIMITS

Built for ordinary web images.

  • Single-file inputs are capped at 40 MB.
  • Very large megapixel counts can use substantial browser memory.
  • JPEG and WebP quality controls are lossy.
  • Keep the page open until the output is ready.
FAQ

About the 1MB target.

Will the result always be under 1MB?

The tool searches aggressively for an output under 1,000,000 bytes. Extremely complex images can reach minimum browser-safe dimensions before the target.

Why can dimensions change?

When quality reduction alone is not enough, the tool gradually reduces pixel dimensions to reach the requested byte limit.

Which format should I use?

WebP is the default because it often keeps better visual quality at small file sizes. JPEG is also available for broader compatibility.
