Compress image tries to reduce an image file size with browser canvas by changing format and quality without uploading the file.
Cómo usarla
- Select a PNG, JPG/JPEG or WebP image.
- Review the original size and dimensions.
- Choose JPG, WebP if available, or PNG when you need to preserve sharpness/transparency.
- Adjust quality for JPG or WebP.
- Compress the image and check whether it reduced or increased before downloading.
Casos de uso
- Lower the weight of a photo before sharing it.
- Try WebP for website images.
- Generate a lighter JPG version when transparency is not needed.
Límites
- Reduction is not guaranteed: it depends on the original format, content and browser.
- It does not resize images; original dimensions are preserved.
- Maximum image size: 15 MB.
Privacidad
Processing happens in your browser; we don't upload this image to Modulaq to compress it.
Errores comunes
- A damaged image or one the browser cannot decode.
- The final file can be larger when the chosen format is not suitable for that image.
- WebP may be unavailable as output in some browsers.
Notas técnicas
- Export uses canvas.toBlob.
- JPG does not preserve transparency; the tool exports over a white background.
- PNG has no quality control and may not reduce file size.
