Frequently asked questions
- Is Batch Image Resize free to use?
- Yes. Batch Image Resize is available on the free plan with 20 daily runs. Paid plans add higher quotas for repeat work.
- What happens to images with different aspect ratios?
- Setting both width and height forces every image into one shape and stretches the odd ones. Setting a single side scales the rest proportionally and is much safer for a mixed batch.
- Why do the resized images look softer?
- Downscaling throws pixels away and needs interpolation. Going from 4000 pixels wide to 500 discards a lot of detail, though a light sharpen afterwards restores some apparent crispness.
- Are my originals overwritten?
- No. The resized files arrive as a ZIP, so the images on your machine are untouched.
- Can I resize upwards as well as down?
- Technically yes, but enlarging cannot invent detail that was never captured. If a batch needs to be bigger, question whether the source images were too small to begin with.
