Questions
Bulk Image Resizer FAQ
Are images uploaded while resizing?
No. Bulk Image Resizer uses browser image decoding and Canvas, so files stay on your device.
Can I resize by only width or height?
Yes. You can use width only, height only, exact dimensions, percentage, fit inside, fill, crop, or presets.
Will small images be enlarged?
Not by default. The Do not enlarge smaller images setting helps prevent accidental upscaling.
Can transparent PNG files stay transparent?
Yes, transparency is preserved when exporting to PNG or WebP. JPG uses the selected background color.
