About this tool
Resize images without losing sharpness
Photos from phones and cameras are often 4000 pixels wide or more, far bigger than a website, email or document needs. Resizing them to the size they'll actually be shown at makes files dramatically smaller, pages load faster and uploads succeed.
Simple resizers scale an image down in a single step, which can leave it jagged or shimmering. This tool downsizes in stages, halving the size until it's close to the target, which keeps edges and fine detail crisp. Resize by longest side to fit a whole batch of mixed portrait and landscape photos into the same box.
Three ways to resize
Longest side, exact width × height, or a percentage.
Fit, fill or stretch
When both width and height are set, fit inside, crop to fill, or stretch.
Bulk with one setting
Resize a whole folder at once and download a zip.
No accidental upscaling
Smaller images are left at their size unless you choose otherwise.
FAQ
Frequently asked questions
How do I resize an image without stretching it?
Use Longest side, or set only a width or only a height; the other side is calculated to keep the aspect ratio. If you set both, choose Fit inside or Fill and crop rather than Stretch.
What size should images be for a website?
Full-width images rarely need to be wider than 1920–2560 pixels; images inside an article usually look sharp at 1200–1600 pixels. Then use the Image Compressor to reduce file size further.
Does resizing reduce the file size?
Yes, usually a lot. Halving the width and height cuts the number of pixels to a quarter, and the file size drops roughly in proportion.
Can I make an image bigger?
Yes. Untick Don't enlarge smaller images. Enlarging can't add real detail, so heavily upscaled images will look soft.
Are my files uploaded anywhere?
No. This tool runs entirely in your browser using JavaScript. Your files and text never leave your device, so it's safe for private or confidential work.
