Social Media Image Resizer
Resize and crop any image to the exact 2026 sizes for Instagram posts, Stories and Reels covers, TikTok, YouTube thumbnails, Facebook and X headers, LinkedIn banners and Pinterest pins — locally, without uploading.
Runs in your browser. Nothing you enter is sent to our servers.
Every platform crops differently, and a photo that looks perfect in the feed loses its head in a Story. This resizer crops or letterboxes your image to the exact pixel size each network wants in 2026, lets you set the focus point so the subject stays in frame, and exports a JPG, PNG or WebP — entirely in your browser.
Frequently asked questions
What is the best Instagram post size in 2026?
1080 × 1350 px (4:5 portrait). It takes the most screen space in the feed and matches the new portrait profile grid. Squares (1080 × 1080) still work but are cropped to 4:5 on the profile.
What size should a YouTube thumbnail be?
1280 × 720 px (16:9), under 2 MB, JPG or PNG. Keep text large and in the centre-left — the duration badge covers the bottom-right corner.
Why does Instagram make my image blurry?
Uploads wider than 1080 px are downscaled and recompressed. Export at exactly 1080 px wide, JPG quality 85–90, and avoid heavy noise or fine text which compress badly.
Is my image uploaded to your server?
No. Cropping and resizing happen with your browser's canvas; the file never leaves your device.
