Frequently asked questions
Can I compress many images and download them as one zip?
Yes. Drop as many images as you like, pick a quality, and click Download ZIP. Every image is compressed and packed into a single .zip file you can save in one click.
Does the quality slider affect every image?
Yes. The slider sets the compression for all images at once. Drag it to balance size and quality — every image re-compresses instantly.
How does PNG compression work here?
PNG images are compressed with UPNG using indexed-color (palette) quantization. The number of colours scales with your quality setting, so lower quality means a smaller PNG while keeping transparency.
Is it free and private?
Yes. Compression and zipping run entirely in your browser with no upload, and it is free with no sign-up, no watermark and no limits.
