Ways to set the size
- Pixels: enter just the width and the height follows the aspect ratio. Enter both with “Keep aspect ratio” on and the image fits inside that box; turn it off to force the exact size (the photo may look stretched).
- Percent: 50% halves the width and the height, leaving a quarter of the pixels.
- Common sizes: one-tap buttons for FHD 1920×1080, HD 1280×720, square 1080×1080 and vertical 1080×1920.
Example: a 4,032 × 3,024 phone photo
| Setting | Result |
|---|---|
| Width 1,280 px | 1,280 × 960 |
| 1,080 × 1,080 px, ratio kept | 1,080 × 810 |
| 1,080 × 1,080 px, ratio off | 1,080 × 1,080 (stretched) |
| 50% | 2,016 × 1,512 |
Good to know
- Enlarging an image cannot add detail that is not there, so it gets blurry. By default small images are not enlarged.
- Big reductions are done in steps to avoid jagged edges.
- Phone photos are first turned upright using their orientation data; rotation and mirroring are applied after that.
- Camera details such as device and location are not kept, and files are never sent to a server.
FAQ
Does resizing reduce the file size?
Yes. Halving the width and height leaves a quarter of the pixels, so the file shrinks a lot. To hit an exact KB limit, use the Image Compressor.
What happens if I turn off “Keep aspect ratio”?
The image is forced to the exact width and height, so it looks stretched or squashed if the ratio differs.
Can I resize many images to the same size?
Yes. Add several images to resize them all with the same settings and download them as one ZIP.
