Get your images to the perfect size
Different platforms want different dimensions — a profile photo, a product thumbnail, a banner, an email signature. Resizing lets you hit those exact pixel targets so an image fits its slot without awkward cropping or blurry upscaling by the platform itself.
The tool reads your image’s original width and height the moment you add it, then lets you type new values. With the aspect-ratio lock enabled, the opposite dimension follows automatically, so your photo never looks squashed. Prefer full control? Unlock it and set both numbers independently.
You can also choose the output format. JPG keeps photographs small, PNG protects transparency and crisp graphics, and WebP offers modern compression that works well for the web. Everything is rendered locally with the Canvas API, so no image ever leaves your browser.
Once resized, you might want to compress the file further for faster loading, or convert it to another format. The related tools below handle those next steps in the same private, in-browser way.
