How to post a PDF on Instagram as an image carousel

1. 1Step 1: Open PDF to JPG and add your PDF.
2. 2Step 2: Choose 150 DPI — an A4 page becomes about 1240 × 1755 pixels, plenty for a phone screen.
3. 3Step 3: Enter the pages to include, such as 1-8, or leave empty for all.
4. 4Step 4: Click Start and download the images (all at once as a ZIP if you like).

Instagram feed posts have long supported shapes from landscape to a portrait ratio of 4:5 (check the app for the latest options). A4 and Letter pages are taller than that, so Instagram will crop them. To choose the framing yourself, open Crop image and use the 4:5 preset on each page — keep the most important content in frame.

Instagram displays images at around 1080 pixels wide, so larger images are scaled down on upload. Resizing to 1080 pixels wide with the Bulk image resizer keeps files small and gives you control over sharpening. Then create a new post, select multiple images in page order and publish.

• Use large text — slides designed for presentations translate better than dense reports.
• Split busy pages into two images, each cropped to one half.
• Lead with a strong cover page that tells people to swipe.

The same images work for other social networks and messaging apps. For LinkedIn, which accepts document uploads directly, you might post the PDF itself — compress it first if it's large.
