Resize
Scale a photo or graphic down to the dimensions you actually need. Resizing is usually the single biggest saving you can make on an image file, because a photo displayed 800 pixels wide gains nothing from being stored at 4000.
This tool accepts JPG, PNG, WebP, GIF, BMP, AVIF, HEIC and TIFF files. Everything is decoded by your own browser, so the formats available depend on what your browser can open - which for HEIC in particular varies between Safari and other browsers.
Because the image is rebuilt from raw pixels, EXIF metadata such as camera details, timestamps and GPS coordinates does not carry into the result. Orientation is applied to the pixels first, so photographs stay the right way up. Embedded colour profiles are also dropped and the output is saved as sRGB, which can shift colours slightly in wide-gamut photographs. Animated files are refused rather than being flattened to a single frame.
No. Resizing happens on your device, which is why it finishes in well under a second even for a large photo. There is no upload to sit through first.
Yes, free with no account and no watermark. Resize one image or work through a hundred; the cost to us is identical either way.
Yes, in every mode except 'exact dimensions'. Setting a width computes the matching height automatically, and vice versa. Use exact dimensions only when you deliberately want to stretch the image.
Making an image smaller is safe and usually improves how it looks on screen. The tool reduces large images in repeated halving steps rather than one jump, which avoids the jagged edges that a single large downscale produces.
You can scale up to 400% using percentage mode, but enlarging cannot invent detail that was not captured, so the result will look soft. For genuine enlargement you need an AI upscaler.
Match the largest size the image is actually displayed at, then double it if you are serving high-density screens. For a full-width banner, 1920 pixels wide is usually enough; for a blog image, 1200 is plenty.
