AM Every platform has its own preferred image size, and camera photos rarely match any of them. This resizer changes the dimensions of your images by exact pixels, by percentage or with presets for Shopify, Etsy, Amazon, eBay, YouTube, Instagram, Facebook and Pinterest. It handles a whole batch in one go and gives you a ZIP at the end.
All resizing happens in your browser, on your device, so product photos you have not launched yet stay private.
How to resize images
- Drag your images into the box at the top of this page, or click it to choose them.
- Choose how to size them: a platform preset, an exact width and height in pixels, or a percentage of the original.
- If the target shape differs from your photo, pick a fit mode: contain (the whole image fits, with padding) or cover (the image fills the frame and the edges are cropped).
- For contain, choose the padding color. White suits marketplaces.
- Choose the output format and, for JPG or WebP, the quality.
- Download each image, or all of them as one ZIP.
Presets and current platform guidance
The presets follow each platform's current published guidance. Platforms revise these numbers, so check the linked help pages when something changes.
| Preset | Size (px) | What the platform says |
|---|---|---|
| Shopify product | 2048 x 2048 | Shopify says 2048 x 2048 usually displays best for square product images; images can be up to 5000 x 5000 px and must be under 20 MB. |
| Etsy listing | 2000 x 2000 | Etsy recommends at least 2000 pixels in width and height, and warns that files over 1 MB may not finish uploading on slow connections. |
| Etsy landscape | 3000 x 2250 | A 4:3 landscape size that clears the 2000 px minimum; Etsy asks for a horizontal or square first photo so thumbnails crop well. |
| Amazon main image | 2000 x 2000 | Amazon needs a pure white background and the product filling about 85% of the frame; images of 1,000 px or more on the longest side enable zoom. |
| eBay | 1600 x 1600 | eBay asks for at least 500 x 500 and recommends about 1600 x 1600, with a 12 MB limit per photo. |
| YouTube thumbnail | 1280 x 720 | 16:9, at least 640 px wide. YouTube now allows up to 3840 x 2160, but uploads from mobile are capped at 2 MB. |
| Instagram post | 1080 x 1080 | Square 1:1 feed post. |
| Instagram portrait | 1080 x 1350 | 4:5 portrait, which takes more screen space in the feed. |
| Facebook cover | 851 x 315 | Facebook's help center gives 851 x 315 and suggests an sRGB JPG under 100 KB. |
| Pinterest pin | 1000 x 1500 | Pinterest recommends a 2:3 ratio, or 1000 x 1500; taller pins may be cropped in feeds. |

Contain or cover: choosing a fit mode
When your photo and the target have different shapes, something has to give. Contain scales the whole image to fit inside the frame and fills the leftover space with a background color, so nothing is cut off. Use it for product photos on marketplaces, where the whole product must be visible, and choose white for Amazon and Etsy. Cover scales the image until it fills the frame and crops what spills over. Use it for lifestyle shots, banners and thumbnails where filling the space matters more than the edges.
There is no stretch mode on purpose. Stretching squashes or widens the product, which misrepresents it to buyers and looks wrong on any product page.
Quality and file size
Downsizing is where most file size savings come from. A 4032 x 3024 phone photo resized to 2048 x 2048 has roughly a third of the pixels, and the file shrinks with it. Enlarging a small image gives you more pixels but no more detail, so upsizing a 600 pixel supplier photo to 2000 pixels produces a soft image. Use the largest original you have.
Which format to save in
| Format | Use it for | Watch out for |
|---|---|---|
| JPG | Product photos for any platform | No transparency; set quality around 80 to 85 |
| PNG | Graphics, size charts, text | Large files for photos; Etsy shows transparency as black |
| WebP | Images on your own website | Not accepted by Etsy or Amazon |
Tips for store and marketplace images
- Keep one aspect ratio across a catalog. Shopify recommends a consistent ratio for featured images so collection grids line up. Square is the easiest to reuse across platforms.
- Frame the product before resizing. Amazon wants the product to fill about 85% of the main image, so crop tight first, then use contain with white padding.
- Batch by destination. Resize the same shoot once for Shopify and again for Etsy or eBay, rather than one size that suits none of them.
Once the images are live, AM Jarvis Bulk Edit Pro handles the rest of the listing in bulk: prices, status, SEO titles and meta descriptions for Shopify and WooCommerce products, with a preview and one-click revert. The Shopify bulk edit guide covers the process, and the image converter changes formats if a platform rejects a file.
Privacy
Resizing runs entirely in your browser, and no file is uploaded to a server. The resized images do not carry EXIF metadata from the originals, so GPS location and camera details are left out.
