How to use it
- Drop one or more images, or tap to choose them.
- Set the percentage and press Resize.
- For exact sizes write them in the box, for example “resize to 1200x800” or “3.5x4.5 cm at 300 dpi”.
- The dimensions of each result are read from the file and compared with the ones asked.
Examples to write in the box: resize to 1200x800
, resize to 1200 by 800
Limits and compatibility
- With the percentage control the image can only get smaller, from 1% to 100%.
- When you give only the width or only the height, the other side follows the proportion.
- With centimetres, the DPI are written into JPG and PNG files so that the printed size is right. WebP has no place for DPI, so that check stays “not verified”.
- JPG results are saved with quality 90. The orientation saved in phone photos is applied to the pixels.
- HEIC, GIF and AVIF are not accepted yet.

Frequently asked questions
How do I resize to exact pixels?
Write the size in the box, for example “resize to 1200x800”. The plan is shown before it starts.
How do I get a size in centimetres for printing?
Write for example “3.5x4.5 cm at 300 dpi”. The pixels are computed from centimetres and DPI, and the DPI are saved in the file.
Does resizing reduce the file weight?
Usually yes, because there are fewer pixels. If you need a precise weight, use Compress image instead.
Will my photo be stretched?
Not when you give a percentage or only one side: the proportion is kept.
