How it worksShow guide
Introduction
Resize Image scales photos to an exact width, height, or longest edge using FFmpeg in your browser. Files stay on your device.
Step-by-step
- Choose one or more images.
- Set width, height, or max edge (and keep aspect ratio if you like).
- Click Resize — FFmpeg runs locally.
- Download the resized files.
Worked example
A 4000×3000 photo with max edge 1200 becomes 1200×900 when aspect ratio is locked.
Use cases
- Shrink camera photos for uploads
- Create consistent thumbnail sizes
- Prepare images for blogs and product listings
Frequently asked questions
Do you upscale images?
By default the tool will not enlarge past the original size when using max edge. Exact width/height can stretch if you unlock aspect ratio.
Are files uploaded?
No. Resizing runs in your browser with FFmpeg.wasm.
