About Image Resizer
This image resizer changes image dimensions to an exact width and height in pixels. Use it to resize an image for a profile picture, a form that demands specific pixel sizes, a blog header or a thumbnail. Enter the size you need, or use a quick scale button, and download the resized copy.
Resizing is done with your browser's canvas using high-quality smoothing, so the image is processed on your device. Because the picture is redrawn and re-encoded, metadata such as EXIF camera details and GPS location is dropped from the output.
How to use
- Drop an image onto the box, or click it to choose one. One image is resized per run, and its original size is shown.
- Type the new Width (px) or Height (px). With Lock aspect ratio on, the other side is filled in for you.
- Or press a Quick scale button: 25%, 50%, 75% or 200%; reset returns to the original size.
- Press Resize and check the new dimensions, file size and format.
- Press Download to save it; the filename gets the new size added, for example photo-800x600.jpg.
FAQ
How do I resize an image to exact pixels?+
Load the image and type the width and height you need. If both sides are fixed and the shape differs from the original, switch off Lock aspect ratio first; the picture is then stretched to fit rather than cropped.
What format is the resized image saved in?+
JPEG, PNG and WebP images keep their format. Other formats your browser can open, such as GIF or BMP, are saved as PNG. JPEG and WebP are encoded at a fixed 92% quality; there is no quality control, so use the image compressor if you also need a smaller file.
Can I make an image larger?+
Yes, for example with the 200% button or by typing bigger numbers. Enlarging cannot add detail, so the result will look softer. Very large targets may fail if the browser cannot allocate a canvas that big.
Can I resize several images at once?+
No. The tool handles one image per run. Download the result, then drop the next image.
What happens to transparency?+
PNG and WebP keep transparent areas. JPEG has no transparency, so a JPEG source stays opaque.
