Image Resizer

Resize images to any pixel, inch, or cm size, right in your browser. No uploads, no sign-up, completely free.

Need it bigger, not smaller?Resizing up makes a photo blurry. The AI upscaler rebuilds the detail instead.

Everything You Need to Resize Images Online

Resize by pixels, percent, longest edge, or target file size. Choose a fit mode, pick your output format, and process one image or a whole batch.

Instant In-Browser Resizing

Resizing happens the moment you click Resize Image. There is no upload wait and no processing queue, so your resized file downloads in seconds.

100% Private, Never Uploaded

Your image stays on your device from start to finish. Nothing is sent to a server, which makes this image resizer safe for confidential photos and client work.

Resize Without Losing Quality

Pick from eight resampling filters, including Lanczos for sharp photo downscaling and Mitchell for a balanced default. A quality slider from 1 to 100 gives you control over JPEG, WebP, and AVIF output.

Resize in Pixels, Percent, Inches, or Centimeters

Switch between px, %, inches, and cm, and set a DPI from 72 for screens up to 600 for professional print. Enter exact pixel dimensions, or scale by a percentage instead.

Resize to a Target File Size

Enter a target size like 100 KB or 2 MB. The tool then tries up to 8 quality settings to find the closest match, so your file fits the limits set by forms and upload portals.

Aspect Ratio Lock and Fit Modes

Lock the proportions so resizing never stretches your photo. Or turn the lock off and pick stretch, cover, contain, or pad to control how the new size is filled.

Frequently Asked Questions

Answers to common questions about resizing images online.

How do I resize an image without losing quality?

Pick Lanczos or Mitchell as your resample filter and keep the quality slider above 80 for JPEG, WebP, or AVIF output. Shrinking an image keeps the most detail. Enlarging it past the original resolution will always soften the result somewhat, whichever filter you use.

How do I resize an image to a specific pixel size?

Switch to Dimensions mode, type your width and height in pixels, and lock the aspect ratio to keep proportions. Turn off the lock and pick the Stretch fit mode if you need an exact width and height that don't match the original ratio.

How do I resize an image in inches or cm?

Switch the unit toggle in Dimensions mode from px to in or cm, then set a DPI between 72 for screen use and 300 or 600 for print. The tool converts your inch or cm value into the matching pixel dimensions automatically.

How do I resize multiple images at once?

Drop more than one file into the upload area to open the batch queue. Set your dimensions, format, and quality once, click Resize, and download every finished file together as a single ZIP.
