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 Detail Image Size: 800×800 (2026 Spec)

AliExpress detail image size: the 2026 spec for slots 2–6

This guide covers the official 800×800 px (recommended), 750×750 px (minimum) specification, format requirements, and the practical workflow imgsize.cc uses to get it right in your browser.

Why these dimensions

AliExpress's detail image gallery slots (2 through 6 on a listing) display in a 1:1 thumbnail grid. The recommended 800×800 pixel upload matches the display size exactly. Detail images can include lifestyle shots, infographics, and feature callouts — the strict white-background rule applies only to the main slot. Maximum 5 detail images per listing.

Specification breakdown

Size: 800×800 px (recommended), 750×750 px (minimum)
Format: JPEG, PNG
Max file size: 3 MB per image, up to 5 detail images per listing
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 Detail Image may crop or overlay UI elements near the edges, so critical content should stay well within the safe zone.

Common mistakes

Image under 750×750 — rejected at upload
Aspect ratio off — letterboxed, listing looks unprofessional
Same image used for main and detail slots — AliExpress flags duplicate-content listings
File over 3 MB — upload fails silently

Frequently asked questions

Can I use portrait or landscape detail images?

No. The 1:1 aspect ratio is mandatory for all AliExpress slots. Non-square uploads are letterboxed with white.

What about video?

AliExpress allows 1 video per listing. MP4, H.264 codec, 720p or 1080p. We don't do video resize — use a dedicated tool like HandBrake.

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 detail slot spec. Resize, crop, and download as an 800×800 pixel PNG — all in your browser, no upload required.
