Resize Image
Make images smaller in pixels, without stretching or squashing them.
Using toolbook means you agree to our Terms and Privacy Policy.
Print sizes are set for sharp photo prints (300 DPI). Web sizes are exact pixel sizes.
Images shrink to fit inside this box. Nothing is cropped or stretched, and smaller images are left as they are.
Lower quality means a smaller file. Around 80% usually looks just like the original.

How to use it
Drop your images here and set a maximum width and height. Each one shrinks to fit without being stretched or cropped. Your images stay on your device.
Phone photos are huge — around 4000 pixels wide. For a website or an email you rarely need more than 1200 to 1920. Resizing is the best way to make a file much smaller: halve the width and the file often drops to about a quarter of the size.
Drop your images onto the box above. Type a maximum width and height, or tap a preset like a print size. Each image shrinks to fit inside that box and keeps its shape, so a mix of tall and wide photos all come out right. The “expected size” line shows the real result before you save.
Images already smaller than your box are left alone. Need exact sizes for Instagram or YouTube? Use Social Media Sizes, which crops to fit.
FAQ
Will resizing stretch my image?
No. With “keep aspect ratio” on (the default), images keep their shape. Turn it off only if you need exact sizes and don’t mind stretching.
What size should I use for a website?
About 1920 pixels wide for full-width images and 1200 for images inside an article. Bigger just slows the page down.
Can I make an image bigger?
You can, but it won’t get sharper — it just looks softer. Making images smaller works best.
Is there a passport photo preset?
Not yet. Passport rules differ by country, so it needs its own tool to get right.
Will my iPhone photo stay HEIC?
On Safari, yes. On Chrome and Firefox it comes back as a JPG. The tool shows which before you save.
How it worksFor the curious
The width and height describe a bounding box. With “keep aspect ratio” on, each image is scaled down until it fits inside, and nothing is enlarged. Turn the option off and every image is forced to exactly the dimensions typed, which distorts anything whose proportions differ.
Scaling uses the browser’s high-quality image smoothing on a canvas in this page. Enlarging is possible with the option off, but it only interpolates existing pixels — no detail is added.
Images keep their format, and the quality slider controls re-encoding for JPG and WEBP. HEIC stays HEIC on Safari, which has a HEIC encoder; Chrome and Firefox have none, so they return JPG. The “saves as” line shows which before you start.
Print presets are computed at 300 DPI, the usual standard for photo prints. Social platform sizes live in their own tool because they need an exact result, which means cropping rather than fitting.
