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.
Can I resize without stretching?
Yes. Leave Keep aspect ratio enabled and changing one dimension updates the other.
Can I enlarge an image?
Yes, but enlarging cannot create real detail that was not present in the source.
Can I change format while resizing?
Yes. Choose WebP, JPEG, PNG, or keep the source format.
