Start with the job at hand
Resize, compress, crop, or convert an image. Your file stays on this device while you work.
The resize, compress, and check tools load in your browser. Nothing is uploaded to a server — all processing happens on this device. If you are reading this, the interactive tool is still loading or JavaScript is disabled.
How it works
Upload your image
Drag and drop or click to choose a JPEG, PNG, WebP, or GIF. Your image never leaves your device — everything runs in your browser.
Choose what to do
Resize to exact pixels, compress to a KB target, convert formats, or validate against submission rules. Switch modes without re-uploading.
Download the result
The preview matches the download exactly. When you’re happy, click Download — the file saves straight to your device.
Our Image Resizer is a free online image resizer, crop tool, and format converter. Resize an image to exact pixel dimensions, crop it to a specific aspect ratio, compress it toward a kilobyte target, or convert between JPG, PNG, and WebP — all without uploading anything to a server.
Everything runs on your device. The image is read, processed, and prepared for download inside your browser tab, so the picture never leaves your device. You can drag and drop or use the file picker, switch between tools without re-uploading, and download the result when it looks right.
The tool is honest about results. When you compress toward a size target it shows the actual size of the file it produced, and if a target cannot be reached it tells you so rather than pretending it succeeded.
FAQ
- Is it free?
- Yes. Every tool on this site is free to use, and no account or sign-up is required.
- Are my images uploaded anywhere?
- No. Images are decoded, resized, compressed, and checked inside your own browser. The image bytes, the filename, and the metadata never leave your device, which you can confirm in your browser’s network inspector.
- Does compressing reduce quality?
- Compressing to a smaller file usually reduces quality, because fitting an image into fewer bytes means discarding some detail. The tool aims to keep as much quality as it can while meeting your target, and it always shows the actual size of the result so you can judge the trade-off yourself.
- Does it work on mobile?
- Yes. The tools run in your mobile browser and adapt to small screens. Very large images can take longer to process on a phone because all the work happens on your device rather than on a server.
- Can I crop an image online for free?
- Yes. The Image Resizer includes a crop mode that lets you set exact output dimensions and choose a crop position. Select crop mode, enter your target width and height, and the tool crops and resizes in one step.
- Can I resize a JPG, PNG, or WebP image online?
- Yes. Upload a supported image, enter the output dimensions, and choose JPEG, PNG, or WebP for the resized file.
- How do I resize an image without changing its proportions?
- Keep Lock aspect ratio enabled while entering a width or height. The other dimension is calculated from the original proportions.
