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.

Compose SHEIN portrait cards on-device, keeping lookbook flats off the cloud

Fashion catalogs are full of unreleased drops, styling flats, and on-model frames that competitors would love to see early. There is no reason to route those through a public editor. This page performs the crop and JPEG encode locally with Canvas, so your apparel imagery stays with you and never reaches VeloTools.

Defaults are set for SHEIN's tall card: a 900×1200 portrait at quality 78, checked against a 5 MB limit. If a shoot needs a different shape, the flexible Image Compress hub runs the identical engine unlocked.

When the tab closes, the draft is discarded from memory — helpful when a seasonal capsule is still under wraps.

Square Western exports that collapse inside SHEIN's 3:4 frame

Sellers arriving from square-first marketplaces paste a 1:1 hero into SHEIN and watch it letterbox or crop a hemline. The card is portrait for a reason: garments read best when the full drape and silhouette fill a taller rectangle. A cramped square strands the outfit in a band of empty pixels.

The opposite failure is a giant runway TIFF that sails past the weight limit even though the framing is right. This URL targets both — enforcing the 3:4 proportion and paring bytes — instead of recycling a generic essay with a fashion label bolted on.

If your flat lay is already shorter than 900×1200, do not inflate it; the fabric texture will only turn to porridge. Start from a higher-resolution capture.

Build a SHEIN 900×1200 portrait in three steps

  1. Drop the on-model or flat-lay frame that misfired on the card — the 900×1200 crop and quality 78 are already set.
  2. Position the garment so the neckline sits high and the hem stays inside the tall box, then process until 5 MB clears.
  3. Download the JPEG and add it to your SHEIN listing yourself; if it still stumbles, recompose or lower quality once on the main compressor.

Why a tall 3:4 at quality 78 flatters apparel

Clothing sells on drape, cut, and texture, all of which need vertical room. The 900×1200 portrait matches how SHEIN renders garment cards on a phone, and quality 78 keeps weave and print pattern honest without letting the file balloon.

Consider the numbers a sensible baseline; consult the platform's current seller guidance whenever your category or campaign specifies its own dimensions.

Drape, silhouette, and the tall-card advantage over squares

Fast-fashion discovery is relentless, and shoppers judge fit in the first glance. A portrait frame lets a dress fall naturally and gives shoes or accessories a stage that a cropped square cannot offer, so the same outfit converts better here than in a marketplace tile.

Selling the same stock across bargain rails too? Line the framing up against the Temu square preset, and for resale-flavored fashion crowds compare the Depop feed size before you export a whole capsule.

Behind the scenes your frame is redrawn onto a 900×1200 canvas and re-encoded as JPEG. The transform is lossy, so keep the styled RAW in your own archive and let the card carry only the selling copy.

Watch the top margin. Cards sometimes gain a badge or price ribbon, and a face or collar shoved against the edge can vanish under that chrome. A little headroom protects the composition.

Assume sRGB output. If studio lighting pushed your palette, correct to sRGB first so the platform does not muddy a signature color after upload.

Geometry alone will not rank a listing; trend relevance, price, and reviews still carry weight. A properly proportioned card simply stops the platform from cropping your styling by force.

SHEIN card imaging questions from apparel sellers

What is the right image size for a SHEIN product card?
This page delivers a 900×1200 portrait at JPEG quality 78 under a 5 MB limit — a practical fashion-card size. Check your live seller guidance if a campaign lists something different.
Is my unreleased lookbook flat uploaded during a SHEIN resize?
No. The work happens in your browser. Only the file you later add to your listing leaves the device.
Can I keep a square crop for a SHEIN card?
Not on this locked page. Use the general Image Compress tool for a free shape, then return for the 3:4 portrait.
Why 3:4 rather than a marketplace square for SHEIN?
Garments read best with vertical room for drape and hemline; a square strands the outfit in empty bands.
My runway export is over 5 MB at 900×1200 — what helps?
Export JPEG instead of PNG, simplify busy backdrops, or take a second pass on Image Compress at the same portrait size.

Field note: Shein

I keep this page because listing image sizes for Shein 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.
