How it works
Pick a maximum size and drop in a whole set of photos. Each one is scaled to fit inside the box, never enlarged, and saved at the quality you choose.
- 01
Set the box
The default fits images inside 1920 × 1920 pixels. Change it in Settings.
- 02
Add your images
Select up to 50 at a time on a computer and 20 on a phone.
- 03
Download the ZIP
Files keep their names, with the new size added.
Fast on your own device
Nothing is uploaded, so there is no waiting for files to travel. Several images are processed in parallel on computers, and one at a time on phones with little memory to keep things stable.
Questions people ask
Will small images be enlarged?
No. Fit inside only ever shrinks images that are bigger than the box.
Can I also set a KB limit?
Yes. Open Settings and choose Max size; every image is then fitted inside the box and under the limit.
How are files named?
Each file keeps its original name with the size added, and names stay unique inside the ZIP.
