Exact dimensions, no distortion

Whether you need a 1080-pixel-wide image for a blog, a precise thumbnail, or a photo scaled to fit an email, this resizer lets you type exact pixel values. Keep the aspect ratio locked and the second dimension is calculated for you, so your image never looks stretched or squashed. Unlock it when you deliberately want a different shape.

High-quality scaling

Reducing an image to a smaller size can introduce jagged edges if done in a single step. This tool uses progressive, high-quality downscaling that produces smooth, sharp results — the same approach professional software uses. For the technical details, see our guide on resizing without losing quality.

Resize, then optimise

Resizing to the dimensions you actually display is the most effective way to cut file size. Pair it with compression or WebP conversion to make images as small as possible while still looking great.

FAQ

Questions & answers

How do I resize an image to specific dimensions?

Open the Resize tab and type the exact width or height in pixels. With aspect ratio locked, the other dimension updates automatically to prevent distortion.

How can I resize without losing quality?

Downscaling (making an image smaller) preserves quality well, especially with high-quality scaling. Avoid upscaling beyond the original size, and export as PNG or high-quality WebP.

Can I resize to a percentage?

Yes. The Resize tab includes quick 25%, 50% and 75% scale buttons, plus a reset to 100% of the source dimensions.

Does resizing happen on a server?

No. Like every feature here, resizing is performed locally in your browser, so it is fast and completely private.
