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.
