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.

AliExpress Main Image Size: 1000×1000 (2026 Spec)

AliExpress image size: the 2026 spec for global sellers

This guide covers the official 1000×1000 px (recommended), 800×800 px (minimum) specification, format requirements, and the practical workflow imgsize.cc uses to get it right in your browser.

Why these dimensions

AliExpress's main image renders at up to 800 pixels wide on the global shopping feed. The 1000×1000 pixel upload covers retina screens. AliExpress enforces a strict pure-white background — off-white backgrounds are auto-flagged by their image review system within minutes of upload. The 1:1 aspect ratio is mandatory.

Specification breakdown

Size: 1000×1000 px (recommended), 800×800 px (minimum)
Format: JPEG (preferred), PNG
Max file size: 3 MB
Aspect ratio: 1:1 (square, mandatory)

The "safe area" inside the frame

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

Common mistakes

Off-white background — listing suppressed within 1 hour
Image below 800×800 — listing rejected at upload
Watermarks or text — listing flagged for review
Multiple products in one frame — listing removed

Frequently asked questions

Can I use lifestyle photos for AliExpress listings?

Only in detail slots 2–6. The main slot requires pure white background and product-only.

Is AliExpress different per region?

Functionally identical. The 6 AliExpress regional sites (RU, ES, FR, US, BR, etc.) all use the same image spec.

How imgsize.cc handles it

Drop your source image into the workbench above. The crop box defaults to a 1:1 aspect ratio matching AliExpress's spec. The export defaults to PNG at exactly 1000×1000 with a pure white background. Resize, crop, and download — all in your browser, no upload required.
