How to use the Social Media Image Resizer
- Drop your artwork onto the box, click to browse, or paste it. A sample painting is loaded so you can see how the sizes behave. The image is resized in your browser and never uploaded.
- Pick the sizes you need from the chips — Instagram, Pinterest, X, Facebook, YouTube, TikTok, LinkedIn and Etsy. All and None select everything or clear the list. Every pick gets its own preview card.
- Decide crop or fit. Under Default for every size, Crop to fill trims the art to the new shape; Fit whole artwork keeps all of it and fills the empty space with Blurred art or a Solid color, with an optional Margin. Each card has its own Crop / Fit switch if one platform needs a different treatment.
- Set the Focal point by dragging on the small picture (or using the arrow keys). Crops keep that spot in view; the dashed boxes show what each crop keeps.
- Choose the Format and Quality, then press Save on a card or Download all (ZIP). Each card shows the real file size of its export.
Crop or fit: what each choice costs
A painting rarely has the same shape as a social media frame, and the mismatch is bigger than it looks. Take a 3:4 portrait painting, 1200 × 1600 px, and put it into a 16:9 frame of 1600 × 900 for X:
- Fit (with Margin at 0) shrinks the painting to 675 × 900 so all of it shows. It covers only 42% of the frame’s width; the rest is fill.
- Crop enlarges the painting to the full width and keeps a 1200 × 675 band from the original — only 42% of its height. More than half of the picture is gone.
Neither is wrong. Crop works for photos of work in progress, details and studio shots, where a tight frame helps. Fit works for finished pieces, where the composition is the point and a collector should see the whole thing. That is why Fit is the default here. The blurred fill takes the colors of the artwork itself, enlarges and softens them and darkens them by 14%, so the frame feels related to the art without competing with it. A solid fill in the wall color of your studio or website looks more like a gallery mat.
When you do crop, the focal point decides which part survives. The tool keeps the chosen point as close to the center of each frame as the image edges allow, so a figure placed on the right third of a canvas stays in a square crop instead of being cut in half.
Recommended sizes at a glance
| Size | Pixels | Ratio | What to know |
|---|---|---|---|
| Instagram portrait post | 1080 × 1350 | 4:5 | The classic tall feed post |
| Instagram 3:4 post | 1080 × 1440 | 3:4 | Matches the taller profile grid tiles Instagram moved to in 2025 |
| Instagram square | 1080 × 1080 | 1:1 | Still accepted, but shows smaller in the feed than tall posts |
| Instagram story / reel | 1080 × 1920 | 9:16 | Full phone screen |
| Pinterest pin | 1000 × 1500 | 2:3 | Pinterest’s recommended pin shape; much taller pins can be cut off in the feed |
| X / Twitter image | 1600 × 900 | 16:9 | Shows uncropped in the timeline as a single image |
| Facebook link image | 1200 × 630 | 1.91:1 | The preview picture when you share a link to your site |
| YouTube thumbnail | 1280 × 720 | 16:9 | The long-standing size, small enough for any upload limit |
| YouTube thumbnail 4K | 3840 × 2160 | 16:9 | What YouTube’s help center now recommends; minimum width is 640 px |
| TikTok photo | 1080 × 1920 | 9:16 | Same frame as a story |
| LinkedIn link image | 1200 × 627 | 1.91:1 | Preview image for shared articles and links |
| Etsy listing, square | 2000 × 2000 | 1:1 | Etsy asks for at least 2000 px in both width and height |
| Etsy listing, 4:3 | 2667 × 2000 | 4:3 | A landscape first photo, which Etsy suggests for the search thumbnail |
Platforms change their layouts every year or two, so treat these as recommendations rather than rules. The ratio matters more than the exact pixel count: a 2160 × 2700 image displays the same as 1080 × 1350, because both are 4:5. If you need a size that is not listed, the Aspect Ratio Calculator gives the matching dimensions for any ratio.
Two details are easy to miss. Instagram’s profile grid shows tiles at 3:4, so a 4:5 post appears there with about 3% trimmed from each side. And Etsy’s help center lists JPG, GIF, PNG, SVG and HEIC as accepted formats — WebP is not on that list — and warns that files over 1 MB may not finish uploading on a slow connection.
Tips from practice
Keep words away from the story edges. The app interface covers the top and bottom of stories and reels with the profile name, reply box and buttons. A common rule of thumb is to keep text and faces out of the top and bottom 250 px of a 1080 × 1920 frame — about 13% each.
Mind the upscale warning. If a card says Upscaled, your file is smaller than the target, and the export is being stretched. It will look soft on high-density phones. Export a larger file from your editor or scan the work at a higher resolution instead.
Watermark after you resize. A signature in the corner of the original can be cropped away in a 9:16 or 16:9 frame. Resize first, then sign each version with the Watermark Adder so the mark sits where you want it on every shape.
Use JPEG for paintings, PNG for flat graphics. Paintings and photos compress well as JPEG at quality 85–90. Lettering, pixel art and flat-color illustrations stay sharper as PNG. If a file is still too large, the Image Compressor for Portfolios squeezes it further.
Post the same crop everywhere for a series. When a collection appears across several platforms, consistent framing makes it recognizable. Set the focal point once, select every size you use, and download them together so they all match.
