The full size reference
Every size the tool can produce, in one table. Last checked on 2026-08-07. Platforms change these without announcement, so confirm anything critical against the platform's own documentation before a launch.
Social platforms
| Platform | Placement | Size | Notes |
|---|---|---|---|
| Square post | 1080 x 1080 | ||
| Portrait post | 1080 x 1350 | Takes the most vertical space in the feed, so it is the best-performing feed format. | |
| Landscape post | 1080 x 566 | ||
| Story or Reel | 1080 x 1920 | Keep text away from the top and bottom 250px, where the interface sits. | |
| Profile picture | 320 x 320 | ||
| YouTube | Thumbnail | 3840 x 2160 | YouTube now recommends 3840x2160. The 2MB cap shown here applies to mobile uploads; desktop allows 50MB. |
| Thumbnail (720p) | 1280 x 720 | The classic size. Still accepted and still fine, but no longer what YouTube recommends. | |
| Shorts cover | 1080 x 1920 | ||
| Channel banner | 2560 x 1440 | Only the central 1546x423 is guaranteed visible on every device. Keep logos and text inside it. | |
| Profile picture | 800 x 800 | ||
| TikTok | Video cover | 1080 x 1920 | |
| Profile picture | 200 x 200 | ||
| Standard pin | 1000 x 1500 | 2:3 is the ratio Pinterest displays without cropping. Taller pins get truncated. | |

| Idea pin | 1080 x 1920 | ||
| Feed post | 1200 x 630 | ||

Marketplaces
| Platform | Placement | Size | Notes |
|---|---|---|---|
| Etsy | Listing photo | 2000 x 2000 | Etsy asks for at least 2000px on the shortest side. Below that it upscales for you, and it looks it. |
| Shop banner | 1600 x 400 | ||
| Shop icon | 500 x 500 | ||
| Amazon | Main product image | 1600 x 1600 | Needs 1000px minimum on the longest side to enable zoom; 1600px is recommended. Pure white background, product filling about 85% of the frame, and no text, logos or watermarks. |
| eBay | Listing photo | 1600 x 1600 | eBay requires at least 500px on the longest side; 1600px unlocks the zoom viewer. |
| Shopify | Product image | 2048 x 2048 |
The YouTube thumbnail advice you have read is out of date
Almost every guide online still says a YouTube thumbnail should be 1280 by 720 with a hard 2 MB limit. Both halves of that have moved.
YouTube's own documentation now recommends 3840 by 2160 at 16:9, with a minimum width of 640 pixels. And the file size ceiling depends on where you upload from:2 MB from mobile, but 50 MB from desktop. If you have been fighting the 2 MB limit, you were uploading from your phone — the same thumbnail goes up untouched from a computer.
1280 by 720 still works and is still accepted. It is simply no longer what YouTube asks for, and on a large modern display the difference is visible. Both sizes are in the preset list so you can pick deliberately.
Why one image for everything does not work
Each placement crops to its own aspect ratio. Upload a square to something expecting 16:9 and the platform decides what to remove — and its automatic crop has no idea which part of your image matters. That is how you end up with a listing photo missing the product, or a thumbnail with the top of somebody's head cut off.
Generating each size deliberately means you choose the framing. The tool centres its crop automatically, which is right most of the time, but check the previews. When the automatic framing gets it wrong on an important image, use the crop tool to frame that one by hand.
Start from the largest original you have
Every output is derived from your source, so the source sets the ceiling. Scaling down looks excellent; scaling up cannot invent detail and always looks soft.
The largest common target here is 2048 pixels for Shopify products, followed by 2000 for Etsy listings and 3840 for a YouTube thumbnail. If your source is smaller than the sizes you have selected, the tool tells you which ones will be enlarged rather than quietly producing something soft.
Where a platform publishes a hard upload limit — YouTube's 2 MB mobile cap being the notable one — the tool searches for the highest quality that fits underneath it rather than handing you a file that will be rejected.
How to resize Images for Social Media and Marketplaces
- Drop your source image onto the box above. The bigger the original, the better every output will be.
- Tick the platforms and placements you need. Selecting several is the point of the tool.
- Check each preview and nudge the crop where the automatic framing has cut something important.
- Download everything as a ZIP with sensible file names.
Limits worth knowing
Every tool has boundaries. These are this one's, stated plainly so you do not waste time discovering them yourself.
- Platforms change their recommended sizes without much warning. The sizes here are checked periodically, but always confirm anything critical against the platform own documentation.
- Automatic cropping centres the frame. It has no idea where the subject of your photo is, so check the previews before downloading.
- A source image smaller than a target size will have to be enlarged, and will look soft. Start from the largest original you have.
