Image Resizer
Resize images in your browser
Drop images here
Supports JPG, PNG, WebP, and HEIC
Tips
Ratio lock — Type one side and the other fills in, so the picture keeps its shape.
Batch — Drop a folder or pick several files. They all resize and download together.
Quality — Lower it for JPG and WebP to make files smaller when detail matters less.
Privacy — Everything happens in your browser. Your images are not uploaded.
How to Resize an Image
Drop your images
Drag photos in or click to browse. JPG, PNG, WebP, and HEIC all work. Add several at once and they resize together.
Set the size
Type a width or a height. With the ratio lock on, the other side fills in automatically. Turn it off to set both freely.
Download
Download each file or grab them all in a ZIP. Everything runs locally in your browser, so nothing is uploaded.
About Resizing Images
Photos from phones and cameras are often larger than needed. A 4000 by 3000 frame can be a few megabytes, which is overkill for a website, an email, or a document. Shrinking it to something like 400 by 300 keeps it sharp where it matters and cuts the file size sharply.
This tool resizes pictures directly in your browser. The image is decoded, scaled, and re-encoded on your device, so your files never leave it. Nothing is uploaded to a server.
You can lock the aspect ratio so the picture keeps its shape, or set width and height freely. For JPG and WebP, a quality slider balances file size against detail. HEIC files convert to the output format you choose, since browsers cannot encode HEIC. We do not add watermarks or impose usage limits.
Frequently Asked Questions
Why should I resize an image?
Large images load slowly and take up space. Shrinking one to the size you actually use, like a 400 by 300 thumbnail instead of a 4000 by 3000 original, makes pages faster and files easier to share.
What formats can I resize?
JPG, PNG, WebP, and HEIC all work here. HEIC converts to the output format you choose, because browsers can decode it but not encode it.
Will resizing lower the quality?
Shrinking an image usually keeps it looking sharp, because the browser resamples the pixels. Enlarging it past the original size can soften it, since there is no extra detail to add. For JPG and WebP you can adjust the quality slider, though values below 70 percent may show visible artifacts.
What does keeping the aspect ratio mean?
It locks the proportions, so a 4000 by 3000 picture resized to a width of 400 becomes 400 by 300. Turn it off to set width and height independently.
Do I need to sign up or pay?
No. You do not need an account, and we never add watermarks or charge for output. Every feature is free and unlimited.
Are my photos uploaded anywhere?
No. Resizing runs entirely in your browser. Your photos stay on your device and are not uploaded or logged.
