Free Image Resizer
Resize images to exact width & height online free. Lock aspect ratio, choose output format, batch up to 10 photos.
About the Image Resizer
Resize any image to exact pixel dimensions with high-quality multi-step scaling that avoids the blur of naive resizing. Lock the aspect ratio to fit inside your target box, or unlock for precise width × height control. Everything runs locally on your device — no upload step, so even large camera originals finish in seconds.
How it works
The resizer computes your target dimensions and scales the image with multi-step downsampling — repeatedly halving before the final pass — which keeps edges noticeably cleaner than a single crude scale. With aspect lock on, changing one side updates the other automatically so nothing stretches.
How to use it
Drop up to 10 images, type a width and height (or set one with the aspect lock on), choose JPG, PNG or WebP output with a quality level, then process. Results show new dimensions per file; download them one by one or zipped together.
Supported formats & limitations
Accepts .jpg, .png and .webp up to 30MB each, 10 per batch. Upscaling beyond the original size is possible but adds softness — for enlargements use the dedicated Enlarge Image tool with its sharpening option.
Common use cases
Everyday sizing for blog content widths, marketplace image rules, profile photos and email attachments. It's also the quickest way to normalize a mixed batch of camera and phone photos to one consistent dimension.
Frequently asked questions
Will resizing reduce quality?
Downscaling with our multi-step algorithm stays sharp. Upscaling can soften detail — use the dedicated Enlarge tool with sharpening for that.
Can I resize many images at once?
Yes — drop up to 10 files per batch and each is resized with the same width, height and aspect settings, while every file keeps its own proportions. Download results individually or grab them all in one ZIP archive.
What's the difference between resizing and compressing?
Resizing changes the pixel dimensions (width × height); compressing reduces the file size in KB/MB. Shrinking dimensions always reduces file size, but you can also compress without changing dimensions — that's what the Image Compressor tools are for.
