Resize Image to Exact Dimensions

Resize any JPG, PNG or WebP image to the exact pixel dimensions you need. Everything happens locally in your browser.
Resizing vs. cropping — two different operations
Resizing changes how many pixels make up your image by remapping the entire grid to a new width and height — it scales everything down or up uniformly. Cropping, on the other hand, removes pixels from the edges without touching the scale of what remains. This tool does the former: when you enter a new width and height, it recalculates every pixel's color using an interpolation algorithm (typically bilinear or bicubic sampling) that blends neighboring source pixels to produce a smooth result at the new size.
When you need an exact pixel count
Plenty of everyday tasks demand a specific width and height rather than "roughly smaller." Marketplace listings (Amazon, Etsy, eBay) often require square product photos at a minimum pixel size. App store screenshot uploads, forum or profile avatars, and government ID photo specifications (commonly given in centimeters but enforced in pixels at a set DPI, e.g. 3.5cm × 4.5cm) all reject files that don't match their exact dimension requirements — not just their file size.
Upscaling behaves very differently from downscaling
Shrinking an image is safe and predictable: you're discarding detail the eye won't miss much. Enlarging an image is a different story — there's no new detail to add, so the algorithm has to invent intermediate pixel values by interpolating between existing ones, which is why upscaled images look progressively softer or slightly blurred the further you push past the original resolution. This is fundamentally different from AI super-resolution tools, which hallucinate plausible new detail rather than interpolate.
Aspect ratio and orientation quirks
If the width and height you enter don't match your source image's original proportions, the image will stretch or squash to fill that exact box unless you lock the aspect ratio. It's also worth knowing that phone photos frequently carry EXIF orientation metadata that some viewers respect and others ignore — a resized image can occasionally appear rotated 90 degrees if that metadata isn't handled consistently downstream.
Frequently asked questions
Will resizing reduce quality?
Downscaling keeps quality high. Upscaling beyond the original size may look softer.
Are my images uploaded?
No — everything runs in your browser and your files stay on your device.
Does the tool lock aspect ratio automatically?
You can enter width and height independently, but if they don't match your source image's proportions, expect stretching — use matching ratios if you want to avoid distortion.
Are my images uploaded anywhere?
No — resizing runs entirely in your browser and your files never leave your device.
Can I resize multiple images to the same dimensions at once?
Yes, you can process several images in one session, which is useful when a batch of product or listing photos all need to match the same exact pixel size.
What happens to EXIF metadata like camera info or GPS location?
Resizing re-encodes the pixel data, and metadata such as camera settings or embedded location is typically stripped in the process — a side benefit if you're sharing photos publicly.
Which formats can I resize?
JPG, PNG and WebP are all supported as both input and output, so you can convert format and dimensions in the same step.
