Image Resize Methods

To resize images Arles uses advanced resample algorithms like Mitchell and Lanczos 3, which produce superior quality thumbnails and images. You can set the image resize method for both thumbnails and images.

Which resize method should I use?

For top quality images use either Mitchell or Lanczos 3. Lanczos 3 is the default and arguably produces the best thumbnails of photographic images when used in combination with a sharpen filter. The Mitchell filter generally shows a little less ringing artifacts than the Lanczos 3 filter, but the thumbnails are also a bit less sharp. Some of the other filters are faster, but produce lower quality images.

Mitchell is generally your best choice if you want to make your images larger (yes you can do that too).  Lanczos 3 is also recommended for graphic type images. It produces the sharpest results with the least smoothing.

Tip

If your images look somewhat fuzzy make sure you select a sharpen filter.
