Social media managers live and die by their content calendar — and wrong image sizes are one of the most common (and entirely avoidable) mistakes. A profile photo cropped wrong. A cover image that pixelates. A post that's squashed on mobile. Glopix.app eliminates all of that.

We provide 85+ preset sizes covering every image type across 15+ platforms: Instagram, TikTok, Facebook, Twitter/X, LinkedIn, YouTube, Pinterest, Discord, Snapchat, Threads, Reddit, Twitch, and WhatsApp. Each preset is verified against current platform specifications. One click crops and resizes to exact pixel dimensions. No guessing, no manual calculations.

    Go to your platform page — Instagram, TikTok, LinkedIn, etc. — and you'll see all the preset sizes for that platform.

Frequently Asked Questions

What are the correct image sizes for Instagram in 2026? expand_more

Instagram post (square): 1080×1080px. Portrait post: 1080×1350px. Story/Reel: 1080×1920px. Profile photo: 320×320px. All presets are available at /imagetools/instagram/.

How do I resize the same image for multiple platforms at once? expand_more

Use the Batch Processor at /imagetools/batch/. Upload your source image, apply each platform's dimensions, and export all sizes as a ZIP.

Do platform image size requirements change? expand_more

Yes — platforms update their specs regularly. Glopix presets are maintained and verified against current specs as of 2026. Always check our platform pages for the latest dimensions.

Can I schedule resized images directly to social media? expand_more

Glopix is an image processing tool, not a scheduler. Download your optimized images and upload them to your preferred scheduling tool (Buffer, Hootsuite, Later, etc.).

What's the optimal image format for social media? expand_more

JPG for photos, PNG for graphics with text or transparency, MP4/GIF for animated content. The platform automatically converts on upload, but starting with high quality reduces degradation.
