Resize an image without uploading it
Set a new width, a new height or a percentage. The aspect ratio is preserved by default and the work happens entirely inside your browser.

JPG, PNG, WebP, GIF or BMP — the file never leaves your browser
The image is processed inside this tab. Nothing is sent to a server, and EXIF metadata, including GPS location, is not copied into the output file.
Step by step
- Choose or drop the image.
- Enter a width, a height or a percentage.
- Check the calculated output dimensions.
- Download the resized image.
How do you resize an image without distorting it?
Fill in only one side. Give it a width and the height is derived from the original ratio, so the image shrinks or grows without stretching.
When both sides are given, the image is fitted inside that box with its ratio intact — the more restrictive side wins. If you genuinely need both exact measurements, there is a stretch mode, but it distorts the image on purpose.
Why does it refuse to enlarge by default?
Because enlarging does not create detail. An image 400 pixels wide pushed to 2000 still carries 400 pixels of information, now spread out and soft. The result almost always disappoints someone hoping for more sharpness.
So asking for a size larger than the original keeps the original dimensions unless you explicitly opt into upscaling. It should be a decision, not an accident.
Which sizes do people ask for most?
For social media: 1080 × 1080 for a square post, 1080 × 1350 for portrait and 1920 × 1080 for video or a horizontal cover.
For the web, a width between 1200 and 1600 pixels covers most content images on large screens without wasting weight. For thumbnails and avatars, 150 to 400 pixels.
For documents and forms the constraint is usually file size rather than dimensions — and in that case reducing dimensions is generally more effective than lowering quality.
When to use it
- Profile photo that has to match a required size
- Square crop for a social post
- Banner matching a template exactly
- Photo scaled down to fit a form’s size limit
- Screenshot sized for documentation

Frequently asked questions
How do you resize an image and keep the aspect ratio?
Enter only the width or only the height. The other side is calculated from the original ratio, so the image is never stretched or squashed.
Can you enlarge a small image?
You can, by opting into upscaling. But enlarging cannot recover detail that is not in the file: the result looks softer than the original when viewed closely.
Does resizing reduce file size?
Yes, and it is usually the most effective way to cut weight. Half the width and half the height means a quarter of the pixels, which normally shrinks the file far more than adjusting quality does.
Does a resized image lose quality?
Scaling down keeps as much sharpness as the new size allows and is usually imperceptible. Scaling up always costs sharpness, because the missing pixels have to be invented by interpolation.
