Image & Media
Resize images by percentage, exact dimensions, or social media presets. All processing happens in your browser — nothing is uploaded.
No. All resizing happens entirely in your browser using the Canvas API. Your images never leave your device.
You can upload JPEG, PNG, WebP, GIF, and BMP images. You can also convert between JPEG, PNG, and WebP on output.
Downscaling generally preserves quality well. For JPEG and WebP, use the quality slider to control the compression level. PNG output is always lossless.
