Two tools in one — Batch Resize and Format Converter. Drop multiple images, switch between modes using the tabs at the top, then process all at once. Each image downloads individually.
| Resize mode | How it works |
|---|---|
| By width | Scale down to max width. Height scales proportionally. |
| By height | Scale down to max height. Width scales proportionally. |
| Exact | Fixed W×H. Toggle aspect ratio lock to prevent distortion. |
| Percent | Scale by percentage, 1–200%. Can scale up or down. |
Convert any number of images to JPEG, PNG or WebP in a single operation. Options include keeping original dimensions (format change only) and filling transparent areas with white for JPEG output.
| Format | Best for |
|---|---|
| JPEG | Photos, small file sizes. Lossy compression. |
| PNG | Screenshots, transparency. Lossless. |
| WebP | Web use. Better compression than JPEG at same quality. |
_processed suffix so originals are never overwritten.
