FAQ
Is my image data safe?
Absolutely. All resizing happens directly in your browser using the HTML5 Canvas API. Your images are never transmitted to any server.
What image formats are supported?
You can upload PNG, JPEG, and WEBP images. Output can be saved as PNG (lossless), JPEG (compressed), or WEBP (modern, efficient).
Will resizing reduce image quality?
Enlarging an image beyond its original size will reduce sharpness. For best quality, only reduce dimensions or use the original size. PNG output is lossless.
What is the maximum file size?
The maximum upload size is 10MB, which covers the vast majority of use cases.
