Image Resizer

Drop your image onto the tool or click to browse, then choose "Exact dimensions" and enter the width and height in pixels. The preview updates instantly with the new size and file weight, and the download button saves the resized picture. You can also pick a ready-made preset like 1920×1080 to fill both fields in one click.

Keep the aspect-ratio lock (the link icon between the width and height fields) turned on. With it locked, changing the width recalculates the height automatically — and vice versa — so the image keeps its original proportions and never looks squashed. If you deliberately want a specific width and height that do not match, unlock it. The "Percentage" and "Fit within a box" modes always preserve the ratio.

Making an image smaller is essentially lossless to the eye — you are removing pixels you were not seeing at full size anyway. Enlarging is different: a browser cannot invent detail that is not there, so scaling well beyond the original dimensions can look soft. For the sharpest result, resize down rather than up, keep the quality slider at 80% or higher, and export photos as JPEG or WebP.

Yes. Enter a larger width and height, or set the percentage above 100%, and the tool scales the image up. Keep in mind that upscaling stretches the existing pixels rather than adding new detail, so a small image will not gain sharpness — it just becomes bigger. For modest enlargements it works well; for large jumps the result may look a little soft.

Yes to all three. It is completely free with no sign-up, and the resizing runs entirely in your browser with the Canvas API, so your images are never uploaded — that is why we can say your files never leave your device. The re-encode also removes EXIF metadata such as GPS coordinates. Once the page has loaded you can disconnect from the internet and keep resizing, because there are no network calls involved.
