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.

Prepare an AliExpress listing image without another cloud upload

This page crops and exports the working copy inside your browser. VeloTools does not receive supplier or pre-launch product photos.

The square preset is a VeloTools starting point, not a statement of AliExpress’s current official requirements.

Create a consistent square copy from uneven source images

Supplier images often arrive with different dimensions, framing, and file weights. This page starts with an 800×800 square crop at JPEG quality 75 so listing copies share one repeatable working format.

Center the product with enough space around the edges, inspect small details after encoding, and verify the current AliExpress seller rules before upload.

Create an AliExpress working export

  1. Drop the original photo and position the subject inside the square crop.
  2. Process the 800×800 JPEG 75 working preset and inspect logos, stitching, and small text.
  3. Download the image, confirm the current AliExpress seller requirements, and upload it yourself.

What the square preset changes

The crop converts mixed source geometry into a square and encodes the result as JPEG. This is lossy, so keep the original master and check fine details after export.

If the source is already correctly framed and only needs a lighter encode, use Image Compress.

Keep the master separate from marketplace copies

Do not upscale a small downloaded thumbnail or repeatedly recompress an earlier export. Start from the best available source and derive a fresh channel copy.

Square framing needs deliberate side clearance. Centering by canvas coordinates is not always the same as centering the visible product: a handle, cable, long sleeve, or cast shadow can shift the visual weight. Compare the crop at thumbnail size and leave breathing room for any destination-side trim.

Inspect the downloaded JPEG for block artifacts around logos, stitching, jewellery edges, and thin typography. Factory images passed through messaging apps may already be compressed; encoding them again can expose damage that was hard to notice in the source. When that happens, request the original asset rather than sharpening a degraded copy.

Keep colour-critical products tied to a reviewed master. Browser canvas export is intended for practical listing copies, not colour-managed print work. If a brand red, skin tone, or material finish shifts, fix the source colour workflow first and then derive a fresh square output.

The 5 MB indicator is a VeloTools workflow target, not an acceptance guarantee. Confirm the current format, image count, prohibited overlays, category rules, and any seller-account-specific instructions in AliExpress before publishing the listing.

For variant-heavy listings, export a repeatable sequence rather than a loose folder of squares. Keep the same crop scale for colour variants, name each copy with the seller SKU and view, and compare the grid side by side. A technically valid file can still create a poor catalog handoff when the blue item is framed tighter than the red one.

Small products need a different review from apparel or appliances. Jewellery clasps, printed model numbers, and texture changes can disappear at the working output size even though the centered silhouette looks clean. Inspect one full-size download and one thumbnail before processing the rest of the supplier set.

For another square working preset, compare Amazon or TikTok Shop. Current platform rules remain the final authority.

AliExpress image-resizer questions

Are 800×800 and 5 MB official AliExpress requirements?
No. They are VeloTools working defaults on this page. Verify the current requirements in AliExpress seller tools before upload.
Does VeloTools store my AliExpress listing photo?
No. The AliExpress working copy is created inside your browser, and you decide when to upload the downloaded file to the seller portal.
Why should I keep the original image?
The crop and JPEG encode are lossy. The original master is the safer source for future channel exports.
How should I review the square export?
Open the downloaded JPEG and inspect side clearance, logos, stitching, small text, colour, file size, and the current AliExpress seller requirements.
What if the source is already square?
Use this page for a consistent working copy, or use Image Compress when you only need to adjust file weight.

Prepare the next image locally

Drop an image, review the crop and output settings, then verify the destination requirements before upload.

From the builder: a square AliExpress handoff

Supplier folders arrive with uneven crops and repeatedly compressed previews. I use this page to make a clearly named square review copy, inspect stitching, logos, and variant framing, and only then compare it with the current AliExpress seller requirements.
