Lower quality usually makes a smaller file. Resizing large images can save much more than quality reduction alone.

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
JPG compression notes.
Does the file leave my device?
No. The browser decodes and re-encodes the image locally.
Can compression change image quality?
JPG compression is lossy when the quality control is below 100%.
Can the output be larger?
Yes. Re-encoding does not guarantee a smaller file for every source. The result card shows the exact before-and-after sizes.
