The right size for every upload

Many forms and platforms reject photos that are too big. Set an exact width or height — the other side follows automatically — or shrink by 25%, 50% or 75%.

Images are scaled down in steps for sharper results than a single resize, then saved in the format you choose.

    Pixels or a quick percentage.

    In JPG, PNG or WebP.

Frequently asked questions

Will resizing reduce quality?

Making images smaller keeps them sharp. Making them bigger can't add detail — try our AI Image Upscaler for that.

Which format should I choose?

JPG or WebP for photos, PNG for graphics with text or transparency.

Is my data uploaded anywhere?

No. Everything runs in your browser with JavaScript — nothing you type or open is sent to our servers.
