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.
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.
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.
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.
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.
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.
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.
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 publish.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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 publish. TagPeek on the live URL confirms whether you succeeded.
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.
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.
