Frequently asked
What's the best image size for Facebook link previews?+
1200×630 pixels. It also works well on LinkedIn, WhatsApp and most other platforms. X accepts up to 1200×675.
What size should Instagram posts be?+
1080×1080 for square posts, 1080×1350 for portrait and 1080×1920 for Stories and Reels covers.
Cover vs. Contain — which should I pick?+
Cover fills the whole canvas by cropping edges. Contain fits the entire image with letterboxing — useful for logos or text you can't crop.
Is my image uploaded anywhere?+
No — resizing happens entirely on your device using the browser's canvas. Nothing leaves your computer or phone.
What formats are supported?+
Any image your browser can open — PNG, JPEG, WebP, GIF, BMP. Output is PNG for maximum compatibility.
Is the image resizer free?+
Yes — free with no signup, no watermark and no limits.
