Questions
How do I resize without stretching?
Leave Keep proportions ticked and enter only the width or only the height. If you enter both, the image fits inside that box.
What size for social media?
Common sizes: 1080 × 1080 for a square Instagram post, 1080 × 1920 for stories and reels, 1200 × 630 for link previews, 1500 × 500 for an X header.
Can I make an image larger?
Yes, but enlarging can't add detail, so big increases look soft.
Is my images uploaded to a server?
No. The tool runs in your browser and works on your images directly on your device. Nothing is sent to us or anyone else, which is why it also keeps working if your connection drops after the page loads.
