Are large images causing upload failures or slow loading times? This tool quickly compresses common image formats like JPEG and PNG. It supports proportional resizing and outputs optimized image files, significantly reducing file size while maintaining visual quality.
The maximum file size for a single upload is 10MB. Please be mindful of privacy when processing sensitive images. Vector format conversion is not supported. Unstable network conditions may cause processing failures.
For web image optimization, we recommend setting JPEG compression quality to 60-80%. For PNG images, consider converting them to WebP format for better compression results. For social media images, a maximum width of 1200 pixels is recommended.
