Resize JPG
Change the width and height of JPEG images, private in your browser
Set exact dimensions for your JPEG
Every platform has its ideal image size. A profile picture, a forum avatar, a product photo or a printout each expect certain pixel dimensions, and resizing lets you hit those targets precisely instead of relying on the site to crop or squash your photo. Enter a new width and height, and the tool redraws the JPEG at that size.
Keep the aspect ratio locked to scale proportionally without stretching, or unlock it to force an exact shape. The whole thing runs in your browser, so there is no upload, no watermark and no waiting.
How to resize a JPG
- Drop your JPG into the box above, or click to choose it.
- Type the width or height you want. Keep the lock on to preserve the proportions automatically.
- Check the live preview to confirm the new size looks right.
- Click Download resized JPG to save it.
Why resize a JPG?
Fit any platform requirement
Match the exact pixel dimensions a site, form or template asks for so your image is never rejected or awkwardly cropped.
Shrink oversized photos
Scaling a huge camera image down to the size you actually need also cuts the file size, which speeds up uploads and page loads.
Proportional or precise
Lock the aspect ratio for a clean proportional scale, or unlock it when a layout needs an exact width and height.
Frequently Asked Questions
Will resizing keep the aspect ratio?
Yes, as long as the lock is on. Change one dimension and the other adjusts automatically so the photo never looks stretched.
Can I make an image larger?
You can enter bigger dimensions, but enlarging a JPEG beyond its original size cannot add detail and may look soft. Downscaling always stays crisp.
What size should I use for social media?
It varies by platform, but square images around 1080 by 1080 pixels work well for most feeds, and 1200 pixels wide suits blog and article headers.
Does resizing reduce quality?
Making an image smaller keeps it sharp and shrinks the file. Only upscaling risks softness, since there is no extra detail to invent.
Are my files uploaded?
No. Resizing happens in your browser, so your image stays on your device.
