Resize Image Online
Resize JPG, PNG, WebP, and AVIF images to pixel-exact dimensions or by percentage, with the aspect ratio locked so nothing ever stretches. Everything happens in your browser — files are never uploaded anywhere.
Hit the exact size a website demands, shrink a photo before sending it, or scale a whole batch down to one consistent maximum edge. The quality is the part worth noticing: downscaling runs through a stepped halving schedule instead of one abrupt jump, so fine detail stays crisp and smooth where most online resizers leave it jagged.
How to resize an image
- Add your image. Drag a JPG, PNG, WebP, or AVIF onto the drop zone, or click it to browse. Drop several to resize a whole batch at once.
- Choose a size. For a single image, enter the exact width and height in pixels. For a batch, scale by a percentage or fit every image inside a maximum edge like 1920px — both stay relative to each picture, so a mixed set keeps its proportions. Leave the aspect-ratio lock on and nothing stretches.
- Resize and download. Pick your output format, click Resize, and download the result — or the whole batch as a zip.
Frequently asked questions
Can I resize to exact pixel dimensions?
Yes. Enter the exact width and height you need — 1920×1080, 500×500, or anything else — and the image is resized to precisely that. You can also scale by percentage, or fit images inside a maximum edge, which is the better choice for a batch of mixed sizes.
Will resizing distort my image?
Not if you keep the aspect-ratio lock on: width and height scale together, so the image never stretches. Unlock it only when you deliberately want to force a shape, since that will squash the picture.
Does resizing reduce image quality?
Scaling down is handled carefully here — the image is reduced through a series of halving steps rather than one big jump, which is what keeps fine detail smooth instead of jagged. Enlarging is different: no tool can add detail that was never captured, so an upscaled image always looks softer than the original.
Can I resize several images at once?
Yes. Drop in a folder's worth and scale them by percentage or fit them within a maximum edge — both are relative to each image, so a mixed batch keeps its proportions instead of being forced to identical dimensions. Exact pixel sizes apply to a single image, for that same reason.
How do I make an image smaller in file size, not dimensions?
Use Compress Image, which re-encodes at the same resolution with an adjustable quality setting. Resizing down reduces file size too — usually by a lot — so for a photo headed to a web page, doing both is the biggest saving available.
Are my images uploaded anywhere to be resized?
No. Resizing runs entirely in your browser — nothing is uploaded to a server and there's no account to create. The only ceiling is a practical one: files up to 50 MB, and images up to about 16 megapixels, which is what a browser canvas can process reliably.
