How to resize an image
- Add your images. Drag them in or click to browse — batch is supported.
- Set the size. Enter a width and height, or pick a preset (Instagram, YouTube, passport…). Keep Lock aspect on to avoid stretching.
- Choose a mode. Fit keeps the whole image (no cropping); Fill crops to an exact size — perfect for square or fixed-ratio presets.
- Resize & download. Press Resize, then save each image or grab them all as a ZIP.
Fit vs Fill — what's the difference?
Fit scales your image so it fits within the width and height you set, keeping the original proportions — nothing is cut off, but the result may be smaller than the exact box. Fill scales and center-crops the image so it fills the exact dimensions — ideal when you need a precise size like a 1080×1080 Instagram square or a 600×600 passport photo.
Common preset sizes
- Instagram — Square 1080×1080, Portrait 1080×1350, Story/Reel 1080×1920
- YouTube — Thumbnail 1280×720
- Profile & passport — 400×400 avatar, 600×600 (2×2 inch) passport photo
Is it private?
Completely. Every resize runs on your own device — your images are never uploaded, stored or seen by anyone. It works offline once loaded, with no limits and no watermark.
