TikTok Shop

Shop rails want true squares, not cropped 9:16 frames. Lock 800×800 at quality 77 with a 5 MB warning so product stills upload cleanly beside your video creatives.

Drop a camera RAW file in the upload zone. VeloTools reads the file locally and extracts the full-resolution JPEG preview that your camera embeds inside every RAW — then you can compress, resize, or convert that preview straight to JPG, PNG, WebP, AVIF or SVG using the buttons above. Nothing is uploaded, and if no usable preview exists you'll get a clear message instead of a silent failure.

TikTok Shop SKUs resize in the browser before Seller Center

Shop launches and flash SKUs deserve a closed prep loop. Resize to 800×800 at JPEG quality 77, under a 5 MB check, on-device — then upload into TikTok Shop Seller Center yourself.

We never receive the thumbnail. Privacy is browser-local by design, even when creators prep dozens of SKUs between livestreams.

Vertical video frames that fail as square Shop thumbnails

Creators grab a 9:16 video still and upload it as the Shop main image. The cabinet expects a square thumb; faces get clipped, products sit off-center, and the rail looks accidental next to polished competitors. Other sellers ship 2000 px Amazon files that waste quota against a practical 5 MB Shop-friendly ceiling on mobile Seller Center.

This preset matches AliExpress’s 800×800 box but uses quality 77 — slightly gentler — because Shop grids sit beside sharp video content and benefit from a bit more acuity inside the same byte budget without looking crunchy on OLED phones.

AliExpress twin: q75 at 800. Organic feed squares: Instagram 1080. Larger retail: Amazon / Walmart.

Export an 800×800 TikTok Shop main image

  1. Drop a clean still (not a soft video grab if you can avoid it) — 800×800 and quality 77 are locked.
  2. Center the SKU so mobile Shop rails recognize it at a glance, then run resize.
  3. Download under 5 MB and upload in Seller Center; keep vertical creatives separate for in-feed video.

JPEG 77 under 5 MB for TikTok Shop mobile rails

Shop discovery is thumb-sized. Quality 77 on an 800 square keeps colorways distinct without inviting 5 MB failures. It is not a substitute for your video hero — it is the catalog badge beside that video.

Need taller storytelling stills for other networks? Pinterest. Meta commerce: Facebook catalog. Pure compression: Image Compress.

Shop vs organic TikTok ratios and cross-posting traps

Organic TikTok thrives on vertical motion; Shop catalogs still need a trustworthy square identifier. Treat them as different art directions even when the SKU is identical. Pull a high-resolution still from the same shoot, not a compressed screenshot of the For You page that already lost detail.

Cross-posting Amazon masters without downscale slows mobile sellers on flaky connections and invites accidental policy mismatches. Use this 800×800 path for Shop, and keep 2000×2000 Amazon exports for that cabinet alone.

Global stack example: TikTok Shop, AliExpress, eBay, Google Merchant, plus Image Compress for odd one-offs. Policy and invoice PDFs: PDF tools.

When a colorway sells out, retire the thumb from the same master set so leftover creatives do not advertise empty stock during flash campaigns. Pair the square thumb with vertical video — do not force one ratio to do both jobs in Seller Center.

TikTok Shop image FAQ for new sellers

What size should a TikTok Shop main product image be?
Use an 800×800 pixel square JPEG. This page locks that size at quality 77 with a 5 MB check.
Can I use a vertical video frame as my Shop thumbnail?
Better to shoot or export a true square still. Vertical frames get cropped awkwardly in square Shop rails.
Does VeloTools see my TikTok Shop photos?
No. Resizing is browser-only. Seller Center receives only what you upload afterward.
How is this different from AliExpress’s 800×800 tool?
Same dimensions; AliExpress uses quality 75 while TikTok Shop uses 77. Pick the page for the destination you are filling.
Should Shop images match my Instagram grid?
They can share a shoot, but Instagram’s 1080 square is a different export. Run both presets from the master instead of stretching one file.

Field note: Tiktok Shop

I keep this page because listing image sizes for Tiktok Shop kept failing with upload tools or generic presets. Here you resize to the channel box, then compress if the portal still rejects the file. Limits and architecture are documented in Lab Notes — this URL is a micro-instrument for one job, not a keyword clone.
