Pinterest Pin Size: Image and Video Specs, and How to Meet Them

Use a 2:3 ratio. Pinterest recommends 2:3 for images and for videos of 15 to 60 seconds, and says to create vertically because most of its audience is on mobile. The ad specs page turns that into 1000 × 1500 pixels.

All of it was read 11 October 2026. Pinterest also lists safe zones for text and key elements: 270 px at the top, 65 at the left, 195 at the right and 790 at the bottom. Keep titles and faces out of those margins. If your board is image-heavy, the same resizing logic applies to Instagram posts and product images for online stores.

Twenty megabytes per image on the web, per Pinterest’s Pin specs page. The same page recommends 1 GB on the Android and iOS apps. The separate ad specs page, which covers paid Pins only, lists 20 MB on desktop and 32 MB in-app for a .PNG or .JPEG (ad specs).

A JPEG rarely reaches 20 MB, but TIFF or PNG exports from a design tool and full-resolution camera files can. A smaller file also uploads faster over a phone connection, and a 4032 × 3024 photo has far more pixels than a 1000 × 1500 Pin. The Pin specs page gives no image resolution recommendation, so the ratio and the quality of the source are what you control.

For scale, on 24 small (768 × 512) high-quality JPEG photos, Smol at default settings made the files 69.3% smaller (benchmark, Smol 1.0.35, 9 October 2026). Camera-size files and graphics will land elsewhere, so check your own output.

Video Pins take H.264 or H.265 in .MP4 or .M4V on the web, from 4 seconds to 5 minutes. The Pin specs page states no video file size limit, so check an export before relying on any number.

The ad specs page, which covers paid video only, states up to 2 GB and 4 seconds to 15 minutes (read 11 October 2026). Those are not the organic limits, so do not plan an organic upload around 15 minutes.

Phone video is the usual problem. A vertical 4K clip is far larger than a Pin needs, and 1080 × 1920 is the full-screen size Pinterest names. Reducing resolution and exporting H.264 MP4 gives you the broadest playback; the trade-offs between H.264 and H.265 are in H.265 vs H.264, and the full workflow is in how to compress a video on Mac. For short vertical clips that also go to Reels and Shorts, see the short-form video page.

Pinterest’s Pin specs page lists no separate Idea Pin size and does not mention Idea Pins. Plan for the standard limits above: images at 2:3 and videos at 9:16 or 2:3, from 4 seconds to 5 minutes.

For video, the Pin specs page names 9:16 for full-bleed, plus 1:2, 2:3, 3:4, 4:5 and 1:1. Pick 9:16 for full-screen video and 2:3 for everything else, and confirm in the editor you see, since options change.

Start from a high-resolution source and shrink once. Pinterest’s guidance is “high-resolution assets,” and it warns that “blurry or distorted images and videos will make it difficult for people to see your idea.” Recompressing an already compressed JPEG is how images turn muddy.

One limit to know: fit scales the whole image into the box, so a landscape photo becomes a wide image, not a 2:3 Pin. Fill covers the box and crops it with no control over what is cut. Crop to 2:3 in your design tool first, then run Smol. Metadata is stripped by default, which includes GPS; our GPS guide shows what a phone photo carries.

Crop to 2:3 in your design tool, then run the folder through Smol once. By default originals stay untouched; Smol writes copies with a _compressed suffix by default.

1. 1

   Export Pin designs at the highest quality your tool offers

   Shrinking happens once, in Smol, not twice.

2. 2

   Drag the folder into Smol

   Images and short clips can go in the same batch.

3. 3

   Set images to Compress, JPG, quality 75, fit to 1500

   Use PNG for graphics where JPG shows ringing around text, and compare the two.

4. 4

   Set video to MP4, H.264, resolution reduced

   Aim for 1080 × 1920 on vertical clips. Smol sets quality, not a byte target, so check the result.

5. 5

   Run it and read the per-file sizes

   Find the largest output. If a file is still too big for you, lower the quality a notch and rerun.

6. 6

   Upload in groups of ten

   On the web, Pinterest lets you select up to 10 images or 10 videos at a time.

Free options exist. Compare them on the steps that matter for Pins.

If one design tool already exports everything you post, you may not need anything else. Smol earns its place when the folder is mixed (HEIC photos, graphics, a vertical clip) and you want one pass. The wider comparison is in every method compared.

Smol does not design Pins. Skip it in these cases.

• You need to crop to 2:3, add text or build a collage. Use a design tool; Smol’s fill mode crops without letting you choose what is cut.
• You need pixel-identical files. Smol always re-encodes images, so use a lossless optimizer such as ImageOptim at its default settings.
• You work on Windows, an iPad or a phone. Smol is macOS only.
• You schedule Pins through an online tool that already resizes on upload, and your sources are small. Compressing adds a step.
• You want SVG or JPEG XL output. Smol writes neither.

If you run a team

Solo is $29 for one Mac, Team is $49 for three Macs, and Enterprise is $20 per seat for 5 to 500 seats. Presets live on each Mac, so write the settings down and recreate them on each one.
