The 794px trap
794px 陷阱
Every Etsy seller eventually learns the 794px lesson the hard way. You open your listing, right-click the hero image, save it, and measure the file. It looks respectable. You run it through a checklist, maybe even pass a generic resize tool, and wonder why hover-zoom still will not turn on after re-upload.
几乎每个 Etsy 卖家都会以吃亏的方式学会 794px 这一课。打开 listing，右键保存主图，量一下尺寸——看起来还不错。过一遍检查清单，甚至通过某个通用缩放工具，却纳闷：重新上传后 hover-zoom 为何仍不开。
The saved file is not your upload. Etsy product pages embed Content Delivery Network URLs sized for fast rendering. The il_794xN pattern is a clue: the filename encodes a display width, not the master archive Etsy stored when you clicked publish. Treating that download as ground truth is the 794px trap.
你另存的那份并不是上传原图。Etsy 商品页嵌入的是为快速渲染准备的 CDN 地址。il_794xN 这个模式就是线索：文件名编码的是展示宽度，不是你点发布时 Etsy 存档的 master。把这次下载当真相，就是 794px 陷阱。
Master files live behind different URL patterns when Etsy exposes them. Sellers and tools that care about compliance look for full-size endpoints rather than the preview baked into the DOM. TagPeek documents this in Rule 06 and uses the live listing context to prefer richer sources before applying pixel floors.
当 Etsy 暴露原图时，master 走的是另一套 URL 模式。关心合规的卖家与工具会找全尺寸端点，而不是 DOM 里写死的预览。TagPeek 在规则 06 中写明这一点，并在 live listing 上下文里优先选用更完整的来源，再套用像素底线。
Why does Etsy show a smaller image at all? Performance. Search and category pages load thousands of thumbnails. Shipping a 794px variant keeps latency predictable. Buyers still see a crisp enough photo at card size. The tradeoff is that developers and sellers inspecting page source see the optimized variant first.
Etsy 为何要显示较小的图？为了性能。搜索与类目页要加载成千上万张缩略图。下发 794px 变体能让延迟更可预期。买家在卡片尺寸下仍能看到够清晰的照片。代价是：开发者与卖家查看页面源码时，先看到的是优化后的变体。
The trap has a second layer: browser devtools. Inspecting the img element shows whatever URL the front end requested, which is often the preview even when a larger asset exists server-side. Downloading from devtools repeats the same mistake unless you follow the full-size link chain.
陷阱还有第二层：浏览器开发者工具。检查 img 元素只会看到前端请求的那个 URL，即便服务端还有更大资源，也常常仍是预览。从开发者工具下载会重复同一错误——除非你顺着全尺寸链接链走下去。
Local workflows avoid the trap entirely. If you still have the export from Photoshop, Canva, or Lightroom, drop that file into TagPeek's free detector. Processing stays in your browser; nothing uploads. You get shortest-side measurement, hover-zoom pass/fail against 2000px, first-photo 635px guidance, crop previews, and a copy-ready re-upload recipe.
本地流程可以完全躲开陷阱。若你还有 Photoshop、Canva 或 Lightroom 的导出文件，把它拖进 TagPeek 免费检测器。处理留在浏览器内，不会上传。你会得到最短边测量、相对 2000px 的 hover-zoom 通过/失败、首图 635px 指引、裁切预览，以及可复制的重新上传配方。
When the only copy left is the 794px save, you cannot recover lost detail by upscaling. Interpolation invents pixels; it does not restore thread weave or paper grain. You may cross the 2000px threshold artificially while failing blur checks. Honest fix: locate the original project file or re-shoot.
若只剩 794px 另存件，靠放大无法找回丢失细节。插值是在「发明」像素，并不能还原线脚织纹或纸张颗粒。你可能人为跨过 2000px 门槛，却过不了模糊检查。诚实做法：找回原工程文件，或重新拍摄。
Some shops duplicate listings from templates. The duplicate inherits preview URLs in notes while the true asset sits in a shared drive folder. Establish a single source-of-truth folder per SKU before you audit pixels. TagPeek scores what Etsy serves on the live listing, which is what buyers experience after you publish.
有的店铺从模板复制 listing。副本在备注里继承了预览 URL，而真正素材还在共享盘某个文件夹。审计像素前，先为每个 SKU 建唯一真相来源文件夹。TagPeek 评分的是 live listing 上 Etsy 实际下发的内容——也就是发布后买家体验到的那一层。
Research extensions that estimate sales never needed your master file. They aggregate marketplace statistics. TagPeek deliberately does not estimate sales; we align with Etsy-published listing requirements instead. Comparing Alura, eRank, or EtsyHunt metrics will not reveal CDN preview behavior on your hero image.
估算销量的研究类扩展从不需要你的 master 文件；它们聚合的是市场统计。TagPeek 刻意不做销量估算；我们对照的是 Etsy 公开的 listing 要求。对比 Alura、eRank 或 EtsyHunt 指标，也看不出主图上的 CDN 预览行为。
After you re-upload a corrected master, wait for CDN refresh and re-check on desktop. TagPeek on the listing page confirms whether zoom toggles on with the new asset. Keep the recipe from the detector for the next SKU so export settings stay consistent across the catalog.
重新上传修正后的 master 后，等待 CDN 刷新，再在桌面端复查。listing 页上的 TagPeek 会确认新素材是否让 zoom 打开。把检测器配方留给下一个 SKU，让整本目录的导出设置保持一致。
If you collaborate with a photographer, ask for longest-edge exports that clear 2000px on the short side for square crops, or explicit dimensions in the brief. Prevention beats rescue once the 794px save is the only artifact left.
若与摄影师合作，请要求长边导出在正方形裁切后仍能保证短边超过 2000px，或在 brief 里写明具体尺寸。一旦只剩 794px 另存件，预防远胜事后抢救。
Link this article back to Rule 06 whenever you train new staff: page saves are for inspiration, not measurement. Measurement belongs on the original file or on a live listing audit that understands Etsy's CDN layers.
培训新人时，把本文链回规则 06：页面另存用于灵感，不用于测量。测量应落在原文件上，或落在理解 Etsy CDN 分层的 live listing 审计上。
Browser extensions that overlay sales badges do not fix CDN confusion. They read marketplace statistics, not your file pipeline. Keep research tools in the research phase and compliance tools on the live URL.
叠加销量徽章的浏览器扩展解决不了 CDN 混淆。它们读的是市场统计，不是你的文件流水线。研究工具留在研究阶段；合规工具用在 live URL 上。
Batch editors that rewrite titles across hundreds of SKUs rarely touch image binaries. After a bulk SEO pass, run spot checks on heroes anyway. Metadata perfection with a 794px-derived hero still fails zoom.
批量改写上百个 SKU 标题的编辑器，很少动到图片二进制。批量 SEO 之后，仍应对主图抽检。元数据再完美，主图若来自 794px，zoom 照样失败。
Photographers delivering web galleries sometimes send 2048px long-edge exports where the short side on a portrait product shot sits at 1365px. Always sort by shortest side when you read dimensions, not longest edge marketing copy.
摄影师交付网页图库时，有时给 2048px 长边导出，竖构图产品照短边却只有 1365px。看尺寸时永远按最短边排序，不要被「长边营销话术」带偏。
Archive originals alongside listing IDs in your DAM. When Etsy updates Help articles, you can re-export from source instead of upscaling previews that accumulated over years of right-click saves.
在 DAM 里把原图与 listing ID 一并归档。当 Etsy 更新 Help 文章时，你可以从源文件重新导出，而不是把多年右键另存攒下的预览再放大。
Marketplace coaches sometimes teach screenshot competitor listings for mood boards. Keep those references separate from your measurement folder. A mood board full of 794px saves is fine for inspiration and dangerous for export targets.
有些市场教练会教截图竞品 listing 做情绪板。请把这些参考与测量文件夹分开。满是 794px 另存的情绪板适合灵感，却危险地不宜当作导出目标。
When two co-owners maintain one shop, agree on a naming convention for finals: SKU, version, and shortest-side pixels in the filename. Arguments about zoom often trace back to uploading v2-final-really-final instead of the detector-approved export.
两位共同经营者维护同一店铺时，请约定终稿命名：文件名里写 SKU、版本与最短边像素。关于 zoom 的争执，往往能追溯到上传了「v2-final-really-final」，而不是检测器认可的那份导出。
Listing importers that scrape competitor pages will pull 794px assets by design. If you use imports for inspiration, replace every hero with your own master before you publish. TagPeek on the live URL confirms whether you succeeded.
抓取竞品页的 listing 导入工具，本来就会拉到 794px 素材。若导入只为灵感，发布前请把每张主图换成自己的 master。live URL 上的 TagPeek 能确认你是否成功。
Some SEO plugins suggest alt text and filenames but never inspect binary pixels. Alt text cannot enable zoom; only the uploaded dimensions can. Keep alt optimization separate from the resolution checklist.
有些 SEO 插件会建议 alt 文本与文件名，却从不检查二进制像素。alt 无法开启 zoom；只有上传尺寸能。把 alt 优化与分辨率清单分开。
If your design tool shows canvas size in inches, convert deliberately to pixels at export using 300 DPI only when print requires it. Web listings need pixel floors, not inch labels on the artboard.
若设计工具以英寸显示画布，导出时请有意识地换算成像素；仅在印刷需要时才用 300 DPI。网页 listing 要的是像素底线，不是画板上的英寸标签。
