Bulk or batch image resizer?
They mean the same thing here: apply one set of dimensions and output options to multiple images in a single run. You can crop, fit or stretch the entire batch.
Private, browser-based processing
Your files are processed locally and never uploaded to RightSizeFast. Large batches are limited only by the memory available on your device and browser.
Is the bulk image resizer free?
Yes. There is no signup, usage charge or watermark.
Can I resize JPG, PNG and WebP together?
Yes. You can add a mixed batch and choose one output format for all downloaded files.
Does resizing preserve quality?
Downsizing generally stays sharp, while enlarging a small source can soften it. PNG output is losslessly encoded; JPG and WebP include an adjustable quality setting.
