How to resize for social media
- Upload your photo.
- Pick the platform and format you need from the dropdown — the exact pixel size is shown underneath.
- Click "Resize & Crop." The tool automatically crops from the center to fill the target frame without stretching or distorting your photo.
- Download the result, sized exactly right for that platform.
Why exact pixel size matters
Every platform crops or stretches images that don't match its expected dimensions, and it's rarely obvious until after you've already posted. A LinkedIn banner sized for Facebook cover will get cropped oddly on both sides. A vertical photo dropped into a YouTube thumbnail slot gets squeezed into a wide frame, distorting faces and text. Getting the pixel size right before uploading means the platform displays your image exactly as intended, with no unexpected cropping from the platform's own auto-resize.
FAQ
Will my photo look stretched?
No — the tool crops to fill the target aspect ratio rather than stretching the image, so proportions stay natural.
Can I control which part of the photo gets kept?
The current version crops from the center, which works well for most photos. For very off-center subjects, crop the image beforehand so your subject sits centrally.
Is my photo uploaded anywhere?
No — resizing happens locally using the Canvas API in your browser.
Which size should I use for an Instagram Reel cover?
Use the Instagram / Facebook Story preset (1080×1920) — it matches the same 9:16 vertical frame used for Reels and Stories.
Do I need a different size for dark mode vs light mode banners?
No — the pixel dimensions stay the same regardless of theme; only the design content inside the image needs to account for how it will look against different backgrounds.
