Resize Image
Resize to exact pixels, a percentage or a size limit.
About Resize Image
Resize one image or a hundred to an exact width and height, a percentage of the original, or whatever fits under a maximum dimension — with the aspect ratio locked by default so nothing comes out stretched.
Almost every platform has a size it wants and will not say so until you have already tried. A profile picture that must be square and under a megabyte, a header that must be exactly 1500 pixels wide, a document upload that rejects anything over 2000.
Set the dimensions once and every image in the batch comes out at them — by exact pixels, by percentage, or by capping the longest edge so mixed portrait and landscape shots all fit the same box.

How Resize Image works in your browser
Resizing goes through a canvas with high-quality smoothing enabled, which is the browser’s own bicubic-class resampler rather than a naive pixel drop. The format is left alone by default, because changing it was not what you asked for — but it can be changed in the same pass when a platform wants something specific.
The aspect ratio is locked unless you unlock it, so setting a width computes the height. Unlocked, you get exactly the pixels you typed and the image is distorted to fit them, which is occasionally what a specification demands and never what looks right.
Reducing an image is close to free in quality terms; enlarging is not. There is no detail in the file that was not captured, so scaling up interpolates between the pixels that exist and produces something larger and softer. Nothing here can change that, and a tool claiming otherwise is either guessing or running a model somewhere else.
When to use it
Bringing a folder of photographs under an email or upload size limit in one pass. Producing the exact pixel dimensions a marketplace, job board or CMS insists on. Shrinking phone photographs before putting them into a document, where full resolution only bloats the file. Standardising a mixed set of images so they sit consistently in a gallery or a grid.
Frequently asked questions
Can I resize a batch to the same size?
Yes — the settings apply to every file you drop in, which is the usual reason for needing this at all: a folder of photographs that must all fit the same box.
Will enlarging an image improve it?
No. Enlarging invents pixels from the ones already there; the result is bigger and softer, never more detailed. Resizing down is lossless in the ways that matter.
What stops images coming out stretched?
The aspect ratio is locked by default, so setting a width computes the matching height. Unlock it only when a format genuinely demands exact dimensions and you accept the distortion.
