How it works
The tool redraws each image at the requested dimensions, always keeping its proportions. The original format is kept: a JPG comes out as a JPG, a PNG as a PNG.
The four ways to resize
Width sets the width, and the height follows on its own. It’s the most used setting, especially for preparing images for a website.
Height does the opposite, useful for lining up images of different formats in one row.
Fit in a box makes the image fit within a box of a given width and height, whatever its orientation. Handy for processing a batch mixing portraits and landscapes in one go.
Percentage shrinks the whole batch in the same proportion, keeping the size differences between images.
Why the image is never distorted
Proportions are always respected. Stretching a photo to fit an exact format visibly damages the result, and it’s rarely what you actually want. If you need an exact framing, you need to crop, which is a different action.
In box mode, the tool doesn’t enlarge beyond the real size either: adding pixels that don’t exist only makes the file heavier and the image blurrier.
Frequently asked questions
Are my images sent anywhere? No. You can check for yourself in thirty seconds: here is how.
Does quality drop? Shrinking an image necessarily loses pixels, but the result stays sharp because the tool resamples cleanly. Enlarging, on the other hand, creates no detail.
Can I process several images at once? Yes, as many as you like, with the same setting for the whole batch. The result downloads image by image or in a zip archive.
Is EXIF data kept? No. Date, camera model and GPS location disappear from the resulting image.
What about the HEIC photos from my iPhone? Browsers can’t open them. They first need to be exported as JPEG from the phone.
