About this image tool
The compressor draws your selected image to a canvas in your browser and exports it in the format you choose. WebP and JPEG can offer smaller files at lower quality settings, while PNG is useful when transparency and lossless output matter. The exact reduction depends on the original image, dimensions, format and quality setting. Compression is not guaranteed to make every file smaller, so check the output size before replacing your original.
Frequently asked questions
Which format should I choose for a smaller image?
WebP is often a useful choice for web images. JPEG is widely compatible for photographs, while PNG is a good option for transparent graphics.
Will compression reduce image quality?
JPEG and WebP use lossy compression at adjustable quality levels. Higher quality usually preserves more detail but creates a larger file. PNG export is lossless.
Are my images uploaded to a server?
No. The selected image is processed in your browser. The PDF tools load a PDF library from a public CDN, but your selected file is not sent to our website.
