Social Media Image Resizer & Cropper
Crop and resize images to exact recommended dimensions for YouTube, Instagram, X (Twitter), LinkedIn, and TikTok. 100% private.
Why Correct Social Media Image Sizing is Critical
Each major social network uses distinct display aspect ratios and compression algorithms. Uploading an unformatted image often leads to aggressive platform cropping—cutting off heads, logos, and critical headline text—or severe blurriness caused by automated server-side downsampling.
2026 Recommended Dimensions Quick Guide
- YouTube Thumbnail (1280 × 720 px): 16:9 aspect ratio. Clear thumbnails are the #1 driver of YouTube video click-through rates (CTR).
- Instagram Square (1080 × 1080 px) & Portrait (1080 × 1350 px): Portrait (4:5) occupies the most vertical screen real estate on mobile phones, maximizing scroll-stopping power.
- Instagram Stories & TikTok (1080 × 1920 px): Fullscreen 9:16 vertical canvas.
- X / Twitter Feed Post (1200 × 675 px): 16:9 ratio ensures images display fully in Twitter timelines without click-to-expand letterboxing.
- LinkedIn Banner (1584 × 396 px): Ultra-wide 4:1 banner establishing professional personal or company brand credibility.
Frequently asked questions
What does 'Fit with Blurred Ambient Backdrop' do?
If your original photo has a different aspect ratio than the destination (e.g. putting a vertical photo into a 16:9 YouTube thumbnail), ambient blur keeps your whole photo uncropped in the center while filling the empty side bars with an artistic blurred glow of the original image.
Can I adjust the framing crop?
Yes! Use the Zoom and Pan sliders to precisely position the subject of your photo inside the crop frame.
Is my photo compressed or uploaded to a cloud server?
No. The entire cropping, scaling, and canvas rendering executes locally inside your web browser.
