Bild-Kompressor - Compressore di immagini

Modern cameras and smartphones take gorgeous but enormous images. For simply viewing them on a screen you need only a fraction of that data. The image compressor strips out exactly that ballast: it slashes the file size while the image looks practically identical to the eye. 6 megabytes become 400 kilobytes and nobody sees the difference.

The heart of it is the quality slider with an instant before/after preview. You slide the quality down and see live how small the file gets and whether the image still looks good. So for every motif you find the point where the file is minimal without any visible artefacts. No flying blind, just a deliberate decision with a real preview.

When you have to stay under a specific limit, the target size helps. Many forms, job portals or forums only allow images up to a fixed file size. Set the target and the tool finds the right quality so your image lands just under it. No more trial and error until the upload finally goes through.

For the web it is worth a look at the format. JPEG is the classic for photos, while WebP and AVIF compress noticeably better at the same quality and are the smarter choice on modern websites. The tool gives you hints on which format suits your purpose so you save not just smaller but wiser.

With batch processing you compress a whole collection at once. Whether 5 or 50 photos, you set the options once and shrink every image in a single pass. Ideal for making a complete blog post, a product catalogue or an image archive web-ready.

Everything runs data-frugally and starts right in the browser, no signup. In most cases your images stay on your device. No account, no watermark, no hidden limits - just smaller files that load faster and are easier to send.
