About this tool

Resizing sounds trivial and mostly is, but the quality of the resampling matters more than people expect. Naive scaling produces aliasing on fine detail — think brick walls, text, and fabric patterns turning into shimmering moiré. This tool uses high-quality filtered resampling so downscaled images stay crisp rather than getting that characteristic cheap-thumbnail look.

One honest note about enlarging: no resize algorithm can add detail that the sensor never recorded. Scaling a 400-pixel image to 1600 pixels gives you a bigger, softer version of the same information. If you actually need more detail, the AI upscaler is the right tool — it hallucinates plausible texture, which is a different operation with different trade-offs.

Questions

Will resizing make my image blurry?

Shrinking is safe and usually sharpens perceived detail. Enlarging is where blur comes from: the extra pixels have to be invented, so a 200 percent scale-up of a small image will always look soft. If you need to genuinely enlarge, use the AI upscaler instead, which reconstructs plausible detail rather than smearing existing pixels.

What does "longest edge" mean?

It sets a ceiling on whichever side is bigger and scales the other side to match. It is the most useful mode for batches of mixed portrait and landscape photos, because every image ends up within the same bounding box regardless of orientation.

Can I resize a batch to the same size?

Yes — add as many files as you like and every one gets the same treatment. Combined with "longest edge" this is the fastest way to prepare a folder of photos for upload somewhere with a size limit.
