Resize JPG Online Free

About this tool

Use this free online JPG resizer when you need an exact pixel size for email, forms, social posts, or websites. It also resizes PNG, WebP, and GIF in the same workflow—no install and no account.

Processing runs in your browser on PDFImageHub, so your photos are not uploaded to our servers for routine resizing. That keeps everyday edits private and fast on desktop or mobile.

How to use

1. Upload a JPG, JPEG, PNG, WebP, or GIF file with drag-and-drop or click to browse.
2. Enter the target width and height in pixels, or switch to percent for proportional resize.
3. Keep aspect ratio locked to avoid stretching, or unlock for custom dimensions.
4. Preview the result, then download your resized JPG or image file.

Resize JPG online to exact dimensions

Many uploads only accept a specific width and height. Enter those pixel values, lock the aspect ratio if you want proportional scaling, then download the resized JPG. You can also switch to percent when you only need to shrink or enlarge by a ratio.

• Resize JPG / JPEG for forms and email attachments
• Change size of a JPG without desktop software
• Keep proportions with aspect-ratio lock
• Works with PNG and WebP when you need another format later

Tips for clean results

Upscaling a tiny JPG cannot invent detail—start from the highest-quality original you have. For web use, prefer the smallest dimensions that still look sharp. If you also need a file under a KB limit, use Image Size Changer after resizing.
