Bild-Skalierung

Resizing images sounds trivial but in practice it is a constant little nuisance. Sometimes you want a fixed pixel width, sometimes a percentage, sometimes a print resolution in DPI. And heaven forbid you forget the aspect ratio, then the motif gets squashed. The image resizer takes over that arithmetic and shows you the result in a live preview before you download.

You choose how to scale: by pixels when you need an exact width or height, by percentage when you just want smaller, or by DPI when the image is going to print. The aspect ratio stays locked by default so nothing distorts - and can be unlocked when you deliberately want to crop to a fixed dimension.

For the ever-same targets there are presets. Whether profile picture, thumbnail or a social format like Instagram, you pick the template and the right dimensions are set. That saves looking up the pixel counts and makes sure your image is not cropped or shown blurry on the platform.

When your image is going to print, the DPI setting is crucial. For the screen 72 DPI is enough, for good print you want 300 DPI. The tool works out the matching pixel size so your photo stays sharp on paper rather than turning pixelated. No more guessing between screen and print resolution.

With batch processing you scale many images to the same size in one pass. A whole gallery to a uniform web width, a series of product photos to identical dimensions - set it once, all images done. If you like, you can compress the result or output it in another format such as WebP at the same time.

Everything runs right in the browser, no signup. In most cases your images stay on your device. Fast, data-frugal and no watermark - just the right size for the right purpose.
