Does my image actually stay on my device?

Yes. The resize runs in your browser using the Canvas API. We never see, store, or transmit your image. You can verify this in your browser's network tab — only static files load, no upload requests.

What's the catch? Why is this free?

No catch. The whole tool runs in your browser, so there are no servers and no bandwidth costs. We're validating demand first; a paid tier with batch resize and API access may come later.

Can I batch resize multiple images?

Yes — one click exports your photo resized to all 17 marketplace presets as a ZIP. Single-image batch export is built in; multi-image upload is on the roadmap.

Do you support my country's platform?

Yes — imgsize.cc supports Amazon (US, IN), Etsy, Shopify, Walmart, Flipkart, Instagram, TikTok, YouTube, LinkedIn, X, Facebook, Pinterest, Threads, Mastodon, Twitch, Snapchat, Behance, Substack, Medium, Dribbble, Tumblr, Vimeo, SoundCloud, Discord, WhatsApp and Spotify. If we don't have your platform yet, request it via email.

What image formats can I export?

JPEG, PNG, TIFF, and GIF. PNG is the default for product photos because it preserves transparency and is the format Amazon prefers. JPEG is smaller and great for social posts.

Channel Banner Size: 2560×1440 (2026 Spec)

YouTube channel banner image size: the 2026 spec

Getting YouTube channel banner image dimensions right matters for both reach and visual quality. This guide covers the official 2560×1440 pixel specification, format requirements, and common pitfalls when preparing images for YouTube channel banner.

Why 2560×1440 pixels

The 2560×1440 standard is YouTube channel banner's recommended upload dimension. Files smaller than this are auto-upscaled and render blurry on high-DPI screens; files larger are downscaled by YouTube channel banner's CDN. The aspect ratio is 16:9.

Specification breakdown

Size: 2560×1440 px
Format: JPEG, PNG
Max file size: 6 MB
Safe area: 1546×423 px centered (all devices visible)

The "safe area" inside the frame

Crop the central content of your image to the central 70% horizontal, 80% vertical. YouTube channel banner may crop or overlay UI elements near the edges, so critical content should stay well within the safe zone.

Common mistakes

Critical content in corners — clipped on TV/desktop/mobile
Forgetting the safe area — text outside it is invisible on some devices

Frequently asked questions

Why is the safe area so small? TV renders full 2560×1440, but mobile and desktop crop heavily.
