Why pre-resize before you upload?
Every marketplace auto-resizes your upload to its own display size — but the result depends entirely on how your source photo compares to that target. Upload a 4000-pixel photo and the platform downsamples it with a generic, often soft algorithm; upload a too-small 800-pixel photo and it upscales with visible blur. Hitting the recommended pixel spec yourself means the marketplace stores your file as-is and renders it sharp.
Pre-resizing also lets you control the crop. Marketplace auto-cropping routinely cuts off sleeves, labels, handles or the full silhouette of an item. Resize to the right square first — padding to a clean canvas or cropping deliberately from the center — and what you see is exactly what buyers see.
How this resizer works: drop one or more photos, then pick any mix of marketplace and social-media sizes in the left panel — or type a custom W×H — and the workbench renders a live preview on the HTML5 Canvas. Choose Pad for a no-crop canvas (white or any brand color) or Crop to fill, pick JPG, PNG or WebP, then download. One photo across three sizes, or a capped batch across every platform, comes back as a single ZIP — and nothing is ever uploaded to a server.
One source photo, every marketplace size
Cross-listers shouldn't re-export the same shot eight times by hand. Upload once, tick eBay, Amazon, Etsy, Shopify, Poshmark, Mercari, Depop and Facebook Marketplace, and the resizer renders a correctly-sized file for each — 2048 for Shopify, 2000 for Etsy and Amazon, 1600 for eBay, 1200 for the rest, 1080 for Depop — in one pass.
Every file is named photo-amazon-2000x2000.jpg style, so dragging the right size into the right listing takes seconds. Multi-size exports come back zipped.
Every social ratio — Instagram, TikTok, YouTube & more
Marketplaces want squares; social wants portraits, stories and widescreen. One upload covers them all — Instagram post (1080²), portrait (1080×1350) and story/reel (1080×1920), TikTok (1080×1920), YouTube thumbnails (1280×720), Pinterest pins (1000×1500), plus Facebook, X and LinkedIn posts.
Pad centers your product on any canvas with white or a brand color, or Crop fills the frame edge to edge — you see the exact result live before you export, whatever the aspect ratio.
Batch resize product photos — free, in your browser
Flip on Batch mode, upload up to 10 photos on desktop or 6 on mobile, tick every size you need, and download one ZIP with each photo rendered to each platform. No per-image busywork and no daily cap.
It's 100% free and fully local — files are read, resized on the HTML5 Canvas and downloaded without ever being uploaded, with no login and no watermark.

Frequently asked questions from marketplace sellers
What's the best image size for eBay listings in 2026?
eBay recommends 1600 × 1600 pixels on the longest side — the threshold at which eBay's desktop zoom feature activates. Minimum 500 px, maximum 9000 px, JPEG up to 12 MB.
Why does Amazon keep rejecting my main product image?
Nine out of ten rejections come down to background — Amazon requires pure white RGB (255, 255, 255), with the product filling at least 85% of the frame and longest side at or above 1000 pixels.
Is 1600 or 2000 pixels right for Amazon in 2026?
Amazon's 2026 Seller Central guidance recommends 2000–3000 pixels on the longest side. Zoom activates at 1000 px, but 2000 × 2000 is Retina-sharp and under the 10 MB file cap.
What size should I upload to Etsy listings?
Etsy officially recommends at least 2000 × 2000 pixels in 1:1 square format.
What's the recommended Shopify product image size for fast page speed?
Shopify's official guide recommends 2048 × 2048 pixels. WebP delivers files 25–35% smaller than JPEG at identical quality.
Poshmark switched to portrait covers in 2026 — do I need to re-shoot my closet?
No. Poshmark's March 2026 portrait rollout is 3:4 (~900 × 1200), but existing 1:1 square listings remain fully valid.
Why do my Poshmark and Mercari photos look blurry after I upload them?
Almost always because the source photo was smaller than 1200 pixels.
Does Mercari publish an official image size requirement?
Mercari doesn't publish an explicit pixel spec, but the app renders feed thumbnails at roughly 1200 × 1200.
What does Depop's Seller Photography Guide actually require?
1080 × 1080 pixels in 1:1 square format, JPEG or PNG, up to 15 MB per file. Minimum accepted is 640 × 640.
Why do top Depop sellers have such consistent shop grids?
Depop's 3-column grid is effectively your storefront. Top sellers shoot every item on the same backdrop at the same 1080 × 1080 spec.
What image size works best on Facebook Marketplace after its compression?
Meta Business Help specifies 500 pixels minimum and 1200 pixels recommended.
What's the fastest way to resize one source photo for every marketplace I sell on?
Upload it once here, tick every marketplace you sell on in the left panel, and download a ZIP with one correctly-sized file per platform — Shopify 2048 → Etsy/Amazon 2000 → eBay 1600 → Poshmark/Mercari/FB 1200 → Depop 1080.
How many photos can I resize in one batch?
You can upload up to 10 images on desktop, or up to 6 images on mobile. Extra images are skipped with a prompt.
Do my product photos actually leave my device?
Never. The entire pipeline runs locally in the browser — files are read, resized and downloaded without ever being uploaded to a server.
Will resizing from 4000 × 4000 down to 1200 × 1200 blur my photos?
No — downsampling is visually lossless. We render on canvas with high-quality smoothing, so shrinking a large photo stays crisp.
