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 Icon Size: 800×800 (2026 Spec)

YouTube channel icon image size: the 2026 spec

Getting YouTube channel icon image dimensions right matters for both reach and visual quality. This guide covers the official 800×800 pixel specification, format requirements, and common pitfalls when preparing images for YouTube channel icon.

Why 800×800 pixels

The 800×800 standard is YouTube channel icon'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 icon's CDN. The aspect ratio is 1:1.

Specification breakdown

Size: 800×800 px
Format: JPEG, PNG
Display: Circular crop across YouTube

The "safe area" inside the frame

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

Common mistakes

Text in corners — clipped on circular crop
Low resolution — pixelated on TV apps

Frequently asked questions

Channel icon vs channel banner? Icon is the circular profile pic (800×800). Banner is the wide header (2560×1440).
