Profile photos, product listings, forms and email signatures often ask for an image of a particular size. This tool changes the width and height of JPG, PNG and WebP images, either to exact pixels or by a percentage.
Resizing is done in your browser, so personal photos are never uploaded.
How to use
- Select or drop one or more images.
- Choose pixels or percentage.
- Enter the new width or height — with the aspect ratio kept, the other side follows automatically.
- Press Resize and download each image or all of them as a ZIP.
Why use Deftivo
Exact sizes
Type the width and height a website asks for, such as 1080 × 1080 for a square post.
No stretching unless you want it
Keep the aspect ratio switched on to avoid squashed faces; switch it off when you really need an exact box.
Same format out
A JPG stays JPG, a PNG stays PNG with its transparency, and WebP stays WebP.
Resize or compress?
Resizing changes the number of pixels; compressing changes how tightly those pixels are stored. Phone photos are usually far bigger than any screen, so resizing to around 1280–1920 px wide already cuts the file size a lot.
For the smallest file, resize first and then run the image through Compress Image.
Frequently asked questions
Can I make an image bigger?
Yes, with a percentage above 100% or larger pixel values. The image gets bigger but not more detailed, so large enlargements can look soft.
How do I resize several photos to the same width?
Add them all, choose pixels, type the width and leave the height empty with the aspect ratio on. Each photo keeps its own proportions.
Is the photo’s location data kept?
No. Saving the resized image does not copy EXIF data such as GPS location.
