Frequently Asked Questions
What is a bulk image resizer?▼
A bulk (batch) image resizer lets you resize multiple images at once using the same settings, then download them together—often as a ZIP file.
Which batch method is best for mixed portrait and landscape photos?▼
Fit-within is usually best. It keeps aspect ratio and prevents stretching. Longest-side is also great when you only care about a max dimension like 1600px.
Can I resize JPG, PNG, and WebP in bulk?▼
Yes. You can resize JPG, resize PNG, resize WebP in bulk and export to JPG/PNG/WebP with optional quality control for JPG/WebP.
What does “don’t upscale” do?▼
It prevents enlarging smaller images, which can reduce quality. If an image is already smaller than the target, it stays at its original size.
Why do some images get background bars (padding)?▼
If you enable padding to an exact box size, images that don’t match the box aspect ratio keep their shape and get bars added to fill the remaining space—no crop, no stretch.
