Resize Image
Exact pixel dimensions, aspect ratio kept for you.
How to resize an image
- Add an image; its current dimensions fill the width and height fields.
- Type the target width or height; with the aspect ratio locked, the other value follows automatically so nothing gets distorted.
- Untick the lock only when you deliberately want to stretch or squeeze the image.
- Press Resize, check the preview, and download as JPG, PNG or WebP.
Frequently asked questions
- Does enlarging an image improve its quality?
- No. Upscaling spreads the existing pixels over a larger area, which looks soft. Shrinking is safe; meaningful enlargement needs an AI upscaler.
- What sizes are typical for the web?
- Full-width hero images around 1600-2000 px wide, content images 800-1200 px, thumbnails 300-400 px. Larger than the displayed size only wastes bandwidth.
- Which output format should I pick?
- JPG for photos, PNG when transparency or crisp graphics matter, WebP for the smallest files on the web.
- Is my image uploaded anywhere?
- No. Resizing runs entirely in your browser; the image never leaves your device.
