Buyer-facing listing HTML often embeds Etsy CDN URLs such as il_794xN. Those URLs are sized for fast page load, not for auditing your upload. The width in the filename describes the CDN variant, not a promise about your original file.
Why this matters: if you right-click “Save image as…” on the listing, you frequently download a 794px-wide derivative. Measuring that file and assuming your shop passes hover-zoom is the classic false pass — you tested the preview, not the master.
TagPeek resolves toward il_fullxfull (or equivalent full-size URLs) where Etsy exposes them on the listing you have open, so pixel checks reflect stored masters when possible. See also Rule 07 on why sized URLs like il_2000xN mislead.
Local workflows avoid the trap entirely: keep your export from Lightroom, Canva, or Photoshop and drop it into the free image size checker. Processing stays in your browser; nothing uploads to TagPeek servers.
After you re-upload a fixed master, wait for CDN refresh and re-run the extension on the live listing. We do not estimate sales from sharper photos — we report verifiable dimensions and zoom status.
This note comes from DOM calibration across real listings documented in the project’s Etsy DOM calibration work — not from guessing URL patterns.
il_794xN 是 CDN 预览，另存为常不是原图。
TagPeek 尽量解析 il_fullxfull；本地文件检测可完全避开陷阱。
