Image & Photo Tools
Bulk Image Resizer
Resize dozens of images at once to a fixed width, height or percentage, and download them as a ZIP.
Privacy
Your images never leave your device. Files are decoded and redrawn by your own browser using the Canvas API, so nothing is uploaded, queued or logged.
Tips
- Resizing by longest edge is the safest bulk setting: portrait and landscape shots both end up within the same bounding box.
- Never upscale in bulk. Enlarging past the original resolution adds file size and softness without adding detail.
- Everything is processed on your device, so a large batch is limited by your machine’s memory rather than an upload queue.
Frequently asked questions
How many images can it handle?
There is no artificial limit, but each image is decoded in memory. A few dozen photographs is comfortable on a phone; a few hundred is better done on a desktop.
