HOW IT WORKS
Private, browser-first processing.
ImageShaper processes selected files directly in the browser. Your 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.
- 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.
Why use WebP?
WebP can provide smaller files than JPEG or PNG for many web images while still supporting transparency.
Does WebP work with transparency?
Yes. WebP can store an alpha channel.
Is 100% quality lossless?
Not necessarily. The browser encoder uses a quality setting for lossy WebP. This page is optimized for practical web output.
