How do I check a Canva PNG ZIP before publishing a product carousel?

Define the handoff fixture

Create a small approval record before opening the ZIP. Use the Canva design name, the intended page count, the approved page order, and one visual identifier for each page. The identifier should be something you can see in the image, such as the product angle, color, or headline, rather than relying only on filenames.

Illustrative exercise: define Asset A as page 1, a front-facing red insulated bottle with the headline “Leak-resistant lid.” Define Asset B as page 2, a side-view black insulated bottle with the headline “Fits standard cup holders.” These are two distinguishable assets and values. The expected sequence is A, then B. A pass means the extracted files visibly show the red bottle first and the black bottle second; a fail means either file is missing, the order is reversed, or the visible headline does not match its approved page.

1. Record the approved page order in a plain checklist such as 01, 02, 03, using the actual page identifiers from the design.
2. Download the design as PNG through Canva’s download flow. If the account exposes page-selection controls, record whether all pages or only selected pages were chosen.
3. Keep the original ZIP unchanged and extract a working copy into a clearly named folder.

Inspect the extracted files

First count the extracted image files and compare that count with the approved page count. Then inspect each image at full view, not just its thumbnail. Look for a missing page, a duplicated page, a page with the wrong product variant, unexpected cropping, unreadable text, or a transparent or blank-looking export.

Use the file names as evidence of sequence only when they are consistent and unambiguous. The decisive evidence is the combination of file order, visible page content, and the approved record. Do not infer that a ZIP is animated: each PNG is a separate still image.

Follow the evidence branch

Use this short sequence: extract, count, map, inspect, preview, and accept or hold. The branch matters: if the count is wrong, stop before visual publishing and revisit page selection. If the count is correct but one image maps to the wrong page, stop and resolve ordering. If both count and mapping are correct but the preview changes the crop or text legibility, investigate the receiving platform’s carousel preview and hold publication until the displayed result is acceptable.

1. Use a natural numeric filename sort where available, then verify the actual page order from visible content and the approval list. Record each approved page as found; filenames alone do not establish sequence.
2. Record the exact file-to-page mapping in the working checklist.
3. Upload the working copies to the product carousel draft or preview area without publishing.
4. Advance through the carousel and compare its displayed order and framing with the checklist.
5. Accept only when every approved page appears once, in order, with the intended visible content.

Separate format questions

PNG is appropriate for still image pages, while JPG, SVG, and PDF serve different purposes. Do not switch to SVG expecting embedded photographic pixels to become editable paths. A PDF may preserve original cropped photos, but it is not a substitute for checking the PNG carousel handoff. Canva options can vary by account, so record the controls actually shown in your download flow rather than assuming every account exposes the same choices.

A file-size warning should be treated as a separate export issue. The supplied Canva guidance scopes file-size limits to single-page PNG or JPG exports; it does not establish a universal limit for a multi-page ZIP. Capture the warning text and the affected file before choosing a different export path.

Acceptance record

Mark the handoff complete only when the extracted file count equals the approved page count, every file is mapped to exactly one approved page, the visual identifiers match, and the unpublished carousel preview preserves that order and acceptable framing. Save the checklist beside the working copy so a later editor can see what was inspected without altering the original ZIP.
