What the Pinterest Pin Maker does
Pinterest Pin Maker: outputs exactly 1000x1500 px, the size Pinterest recommends for pins (2:3). Everything runs in your browser and the file is never uploaded.
Pick a file and the Pinterest Pin Maker generates it right here in the page. The work happens inside your browser tab, so there is no upload to wait for and no queue.
Most people who open the Pinterest Pin Maker are writers preparing assets for a post. Getting the dimensions right before upload avoids a lot of downstream cropping.
No sign-up, no data collection, no processing queue, just code running locally.
The field table, the method and a worked example are documented after the tool for anyone who wants to check the working.
What do the Pinterest Pin Maker fields mean?
The Pinterest Pin Maker uses 3 inputs. A filled form means you can test one idea immediately instead of sourcing every input first.
| Field | What to enter | Default |
|---|---|---|
| Image file | stays on your device | none |
| Export as | choose from PNG, JPEG or WebP | JPEG |
| Quality % | accepts 10 to 100 | 90 |
How does the Pinterest Pin Maker work?
Each output is derived from the inputs above in a single pass; there is no hidden state carried between runs, so the same inputs always give the same generated output.
Bad input produces a message, not a silently incorrect figure.
What a typical run looks like
You provide: Image file, Export as and Quality %
What happens: the file is read into memory by your browser, processed locally, and offered back as a download. It is never uploaded.
You get back: a new file plus a brief account of what happened to it, shown in the panel.
How long this takes is a property of your computer, not of our infrastructure, and file size is bounded by browser memory.
Pinterest pins sizes
Pinterest is the one major platform that strongly favours tall images. The recommended 2:3 ratio is the opposite of most social platforms, and pins outside it get truncated in the feed.
| Use | Size | Ratio |
|---|---|---|
| Standard pin | 1000 × 1500 | 2:3 |
| Long pin (maximum) | 1000 × 2100 | 1:2.1 |
| Square pin | 1000 × 1000 | 1:1 |
| Story pin | 1080 × 1920 | 9:16 |
| Profile picture | 165 × 165 | 1:1 |
Worth knowing
- Pins taller than 2:3 are truncated in the feed with a "see more" affordance, so the top two thirds must work alone.
- Text overlay is normal and expected on Pinterest, unlike most platforms, but keep it in the upper portion.
- A 2:3 ratio at 1000 × 1500 is the safest default; going larger gains little because the feed renders at around 236px wide.
- Pinterest is a search surface as much as a social one, so the image should communicate the subject without context.
Platforms revise their published specifications from time to time. Where a ratio and a pixel size conflict, match the ratio — every platform downscales an oversized image, but none of them will fix a wrong shape except by cropping it.
How to use it
- Choose your file under Image file, or drag it onto the drop area.
- Pick a value for Export as: the options are PNG, JPEG or WebP.
- Key in Quality % (10 to 100).
- Press Create.
- Check Status on the right.
- Copy Link when you want to return to this exact configuration; Print when someone needs it on paper.
What this tool does not do
- Re-encoding a lossy format such as JPEG always loses some detail, even at maximum quality.
- EXIF metadata may be dropped during processing, which is usually desirable but is worth knowing.
- Intermediate steps are rounded only for display; if you need full precision, work from the source figures.
- The tool trusts your numbers completely, so a mis-keyed digit propagates straight through.
- Large files are limited by your available memory, not by an upload quota.
Frequently asked questions
The form asks for Image file, Export as and Quality %. Every box already holds a working value, so nothing is mandatory before you see a result.
Quality % accepts 10 to 100. Go outside it and you get an error against that specific field instead of a misleading number.
No. The file is read by your browser and processed inside the page. It is never sent to us, which is also why it keeps working offline once loaded.
No charge. Everything on the page is available without signing in.
As accurate as the inputs allow. The arithmetic itself introduces no error beyond display rounding.
