About this tool
The right dimensions make photos look sharper
Resizing is not the same as compressing
Resizing changes the number of pixels, while compression lowers file size by reducing detail. A 4000-pixel photo can be scaled down to 1200 pixels to make it lighter, but enlarging a small photo will not add sharpness that was never there.
Keep the ratio, keep the composition
If width and height are changed without locking the ratio, faces and objects look stretched or flattened. Lock the original ratio for natural results. When you must fill a frame with a different ratio, crop the photo with a deliberate composition first instead of simply stretching it.
Choose a size for the intended use
For a profile picture, 400–800 pixels is usually enough. For a website hero image, match the width of the container so the browser does not have to scale the image up. For print, start at 300 dpi at the final size so the result stays sharp.
Quick guide
How it works Resize Image
-
Open a photo and check its original dimensions
Choose a photo from your device. Note its original width and height so you know how much change is needed before setting a new size.
-
Enter the new dimensions
Type the desired width or height, or use percentage mode, then enable the ratio lock. The preview will show whether the composition still looks balanced.
-
Save a new copy
Download the result under a different name so the original file stays safe. Compare sharpness at the actual display size, not only in the small preview.
FAQ
Frequently asked questions
Does enlarging a photo make it sharper?
No. Extra resolution only spreads the existing pixels, so the photo can look soft. For the best result, start with a high-resolution photo and scale it down as needed.
What size works for a 4R print?
A 4R print is roughly 10 × 15 cm. At 300 dpi, prepare about 1200 × 1800 pixels. If the print will only be viewed from a distance, 200 dpi is still acceptable.
Can I unlock the aspect ratio?
Yes, but the result risks looking stretched. Use a free ratio only for specific design needs, and check faces and round objects so they do not change shape.
Is the resized output a JPG?
Yes, resized images are saved as JPG so they stay light and are easy to upload. Keep the original file if you later need a PNG or WebP version of the same photo.
