Image Resizer
Type a new width and height, or a percentage, and this resizer changes your image's pixel dimensions right in your browser. Lock the aspect ratio to avoid stretching, or turn it off for a free resize.

What does fit mode change?
Crop to fill scales your image up until it covers the new size exactly, then trims the overhang, useful when the new shape does not match the original. Fit inside scales the whole image to fit without cropping, adding a background colour around any leftover space. Stretch forces the exact size regardless of ratio, which can distort the image if the shapes differ a lot.
What is the difference between resizing and cropping?
Resizing changes the total pixel dimensions of the whole image, keeping (or filling around) everything that was in the original frame. Cropping instead removes part of the image entirely to change its shape, without scaling what remains. If you need to cut something out of frame rather than just make the file smaller or larger, use the Image Cropper instead; the two operations solve different problems and this tool only does the first one, aside from the optional crop to fill fit mode.
Why does resizing lock the aspect ratio by default?
Most resizing needs, from fitting a photo into a fixed layout to preparing an image for a specific platform, expect the subject to keep its original proportions. Turning ratio lock off and typing a width and height that do not match the source's own ratio will visibly stretch or squash the image, which is occasionally useful for a deliberate effect but rarely what you actually want, so the lock stays on unless you turn it off yourself.
Frequently asked questions
Will resizing make my image blurry?
Enlarging a small image beyond its original size will soften it, since there is no extra detail to add. Shrinking a larger image down keeps it sharp.
Can I resize by percentage instead of exact pixels?
Yes, switch to percentage mode and drag the slider; the pixel dimensions update automatically based on your original size.
Does this crop my image?
Only if you choose the crop to fill fit mode. The other two modes keep the whole image visible.
Can I resize several images to the same size at once?
Yes, drop in more than one file and the same width, height and fit mode apply to every image in the batch, then download them together as a ZIP.
What background colour fills the empty space in fit inside mode?
If your output format is JPEG, a colour picker next to the fit mode setting lets you choose it, white by default. Output as PNG or WebP instead and the leftover space stays transparent automatically, no colour choice needed.
Does the resizer support every image format?
It accepts the same formats the rest of the site does for standard images (JPG, PNG, WebP, GIF, BMP) and lets you choose the output format separately from whatever you dropped in.
