Uploading a photo that looks sharp on your phone but blurry or cropped on Instagram, YouTube or TikTok is usually not a camera problem. It is a size problem. Each platform crops, compresses and displays images differently, and using the wrong dimensions is the fastest way to lose quality. This guide gives you the exact image sizes that work in 2026 for Instagram, YouTube and TikTok, plus a free way to resize any photo in your browser without installing an app.
Instagram Image Sizes in 2026
Name
Best Image Sizes for Instagram, YouTube and TikTok (2026 Guide)
Date
Catagory
- Profile picture: 320×320 pixels (displayed as a circle, keep faces and text away from corners).
- Square post: 1080×1080.
- Portrait post: 1080×1350.
- Landscape post: 1080×566.
- Story and Reel cover: 1080×1920.
- Carousel images: use the same size for every slide, ideally 1080×1350 for portraits or 1080×1080 for squares.
Tip: portrait posts take up more screen space in the feed, which is why many creators prefer 1080×1350 over square.
YouTube Image Sizes in 2026
- Channel banner: 2560×1440 pixels (safe area 1546×423 in the centre).
- Video thumbnail: 1280×720 pixels, 16:9 ratio.
- Profile picture: 800×800.
- Community post image: 1080×1080 or 1080×1350.
Thumbnails matter most: a 1280×720 thumbnail stays sharp on TVs, laptops and phones, while a small or stretched image looks blurry when enlarged.
TikTok Image Sizes in 2026
- Profile picture: 200×200 minimum, 1080×1080 recommended.
- Video: 1080×1920, 9:16 vertical.
- Photo mode / carousel: 1080×1920.
- Cover image: 1080×1920, with important text kept away from top and bottom edges where buttons and captions sit.
TikTok is fully vertical — a horizontal photo will get black bars or an aggressive crop, so resize it to 1080×1920 first.

How to Resize a Photo for Free, Without an App
- Open the free Image Resizer.
- Upload your photo — everything runs in your browser, so the photo is not uploaded to a server.
- Pick a preset (1080×1080, 1080×1350, 1280×720 or 1080×1920) or type a custom width and height.
- Keep the aspect lock on if you do not want stretching, then download.
- If the file is still too large, compress it with the Image Compressor — targets 20KB, 50KB, 100KB, 200KB or 500KB.
Common Mistakes to Avoid
- Uploading a tiny image and letting the platform stretch it — start from the largest original you have.
- Putting text at the very edges, which buttons and captions cover.
- Using the same square image everywhere.
- Saving every time as a low-quality JPG — resize first, then compress once, at the end.
