Worked example
An image that's 4,000 pixels wide, resized to 800 with proportion locked, becomes 800 by whatever height keeps the same shape. The download is named photo-800w.jpg. Only unlock proportion if you mean to stretch it.
FAQ
- Where does the resize happen?
- Right in your browser, on a canvas. Your files stay on your device.
- What does keep proportion do?
- Height is calculated from the original aspect ratio. Turn it off and you can set width and height separately.
- Which format is the download?
- JPEG. If your image is transparent, it's drawn on white.
- What do the social presets do?
- Instagram Reels, YouTube Shorts, and TikTok cover-crop to 1080×1920. LinkedIn banner cover-crops to 1584×396. Reels also shows a dashed safe-zone guide that isn't saved into the file.
