Frequently asked questions
Quick answers about how this tool works.
What are the current social image sizes?
Instagram square 1080×1080, Instagram portrait 1080×1350, Instagram Story/Reel 1080×1920, TikTok vertical 1080×1920, YouTube thumbnail 1280×720, Facebook post 1200×630, X (Twitter) post 1200×675, LinkedIn post 1200×627, Pinterest pin 1000×1500. Platforms update these occasionally — always double-check before a major campaign.
Fit vs Fill vs Stretch — what's the difference?
Fit (letterbox) keeps the whole image and adds a coloured background. Fill (smart crop) zooms and crops to fill the frame. Stretch distorts proportions and should usually be avoided.
Which format should I export?
JPG for photos, PNG for graphics with text or transparency, WEBP for the smallest file with good quality on modern platforms.
Does it upload my image?
No. All resizing happens in a browser canvas.
Can I batch multiple platforms at once?
You can re-export the same image into each preset in a few seconds — pick a preset, download, switch preset, download again.
