The exact photo size eBay, Etsy, and Facebook Marketplace actually want
The secondhand market isn't a niche anymore. thredUp's 2026 Resale Report (compiled with GlobalData) puts the global secondhand apparel market at roughly $257 billion in 2025, growing 13% year-over-year and on track for $393 billion by 2030 — more than twice the growth rate of apparel retail overall. In the U.S. alone, resale is projected to reach $78.8 billion by 2030, and Gen Z and Millennial shoppers say they'll put 46% of their clothing budget toward secondhand going forward. A lot of that growth is ordinary people listing their own stuff on eBay, Etsy, and Facebook Marketplace for the first time — and every one of those platforms quietly expects a different photo shape than the one a phone camera hands you by default.
Three platforms, three different expectations
None of these publish identical rules, and only some of them publish rules at all:
- eBay (per its own Seller Center photo guidance) asks for a minimum of 500×500px, recommends 1600×1600px or larger so the zoom feature works, allows up to 24 photos per listing, and explicitly bans watermarks, logos, and text overlays on listing photos.
- Etsy (per its own Help Center) recommends listing photos be at least 2000px on the shortest side to enable its zoom feature, and accepts JPG, PNG, GIF, or WEBP.
- Facebook Marketplace doesn't publish a hard minimum the way eBay and Etsy do — but its own feed and search grid crop every photo you upload down to a square thumbnail regardless of the shape it arrived in, so an off-center non-square photo gets an unpredictable auto-crop you don't control.
Why your phone's photo doesn't already fit
A phone camera shoots one native shape by default — typically a 4:3 or 3:4 rectangle, not a square — and it's whatever pixel count your phone's sensor produces, not whatever pixel count the marketplace you're posting to actually wants. That mismatch is exactly what causes the two failure modes people run into: an eBay photo that looks soft because it's below 1600px so zoom never kicks in, or a Facebook Marketplace photo where the item's edge gets sliced off because the platform's own square auto-crop landed somewhere you didn't choose.
The fix: crop, resize, and compress in that order
- Crop to match how the platform displays it. Selling on Facebook Marketplace, or want full control over the thumbnail everywhere? NearIMG's Crop tool has a 1:1 preset built in — use it so you decide what's centered, not an auto-crop after the fact. Selling on eBay or Etsy, where the full frame is shown as uploaded? Crop is optional there; the 4:3 or 3:4 preset (matching most phones' native shape) works fine, or skip cropping entirely if the framing is already right.
- Resize to an exact pixel target, not a percentage. NearIMG's Resize tool takes exact width and height, not just a scale-by-percent slider. For eBay, set both sides to 1600px to unlock zoom. For Etsy, set the shortest side to 2000px. There's no marketplace preset built in — type the numbers in directly, the same way you would for a passport photo or a favicon.
- Compress against the platform's real ceiling, watching the number as you go. NearIMG's Compress tool updates an estimated output size live as you move the quality slider, so you can watch the number instead of downloading, checking, and re-uploading. Etsy's own guidance is that photos well under 1MB are the safest bet for a clean upload; eBay's uploader tops out around 12MB per photo, which a resized JPEG rarely gets close to.
- Convert to JPG if your source is something else. All three platforms accept JPG without issue, and it's the smallest, most universally compatible format for a listing photo. NearIMG's Convert-to-JPG tool takes PNG, WebP, GIF, or BMP as input — and HEIC as well, decoded right in the browser on every browser, not just Safari. If your phone saved the photo as HEIC, there's no need for the old workaround of sharing it through Messages or email first just to get a JPEG: drop the .heic file in as-is and convert.
One rule that's easy to break by accident
eBay's own photo guidance is specific about one thing NearIMG's Watermark tool is otherwise built for: no watermarks, logos, or added text on listing photos, full stop, because it can keep the image from showing up in eBay's own third-party search results. That's a real constraint worth knowing before you reach for the same watermark habit that makes sense on a listing you're posting somewhere else, like your own photos on a rental or classifieds site.
What this doesn't do for you
Being upfront about the gap: NearIMG doesn't remove backgrounds, so a plain, evenly lit surface or wall is still doing that work, the same way it does for any product photo. It doesn't grade a photo against a specific marketplace's approval algorithm either — hitting the pixel and file size numbers above makes a listing photo technically compliant, not necessarily one that sells. And Facebook Marketplace's square auto-crop still applies to the thumbnail grid even after you crop to 1:1 yourself — cropping first just means you're the one deciding where that square lands, instead of leaving it to the platform.
| Platform | Photo spec | NearIMG tools |
|---|---|---|
| eBay | 1600×1600px recommended, JPEG, no watermarks | Resize (exact px) + Compress + Convert-to-JPG |
| Etsy | 2000px shortest side, under ~1MB | Resize (exact px) + Compress |
| Facebook Marketplace | Square thumbnail, no published minimum | Crop (1:1 preset) + Convert-to-JPG |
The short version
Secondhand selling is growing roughly four times faster than apparel retail overall in the U.S., per thredUp's 2026 Resale Report, and each place people list on quietly expects a different photo than the one their phone shoots by default: eBay wants 1600×1600px and no watermark, Etsy wants 2000px on the shortest side, and Facebook Marketplace just crops whatever you give it to a square. Crop to the shape that platform actually shows, resize to its exact pixel target instead of a percentage guess, and watch the live size estimate while compressing — all three steps run on your own device, so the only upload that happens is the real one, to the marketplace itself.
