How to resize an image
- Drop one or more images on the mat.
- Tap a preset, or type a width, a height, or a percentage.
- Choose what happens when the shape changes, then press Resize images.
Fill, fit or stretch?
Fill and crop the edges covers the whole new size and trims what sticks out. Use it for Instagram posts and thumbnails. Fit inside with a background keeps the full picture and adds a coloured border, which is handy for product photos. Stretch forces the exact size and can distort faces, so use it only when the shape is already close. Keep proportions makes the picture as big as possible inside your size without changing its shape.
Social media sizes
Instagram posts look best at 1080 × 1080 or 1080 × 1350. Stories and Reels are 1080 × 1920. YouTube thumbnails are 1280 × 720. LinkedIn banners are 1584 × 396 and Facebook covers display at 820 × 312.
Questions
Does resizing reduce file size?
Making an image smaller in pixels also makes the file smaller. If you need a specific KB size, use the compress tool afterwards.
Can I make an image bigger?
Yes, but enlarging cannot add detail, so very large increases can look soft.
Are my images uploaded?
No. Resizing happens in your browser and the files never leave your device.
