You do not have to resize images yourself. RecurPost accepts uploads up to 30 MB and automatically adjusts each image to fit whichever network you are posting to, so a single upload can go to all of them.

Only what is out of spec gets changed. If an image is already within a network’s limits it is published exactly as you uploaded it. When something does need adjusting, RecurPost:

  • scales the image down if it is larger than the network allows;
  • adds padding above and below, or at the sides, if the shape is outside what the network accepts. Nothing is ever cropped, so no part of your picture is cut off;
  • converts the file where the network requires it, for example Instagram and TikTok only accept JPEG;
  • reduces quality only as a last resort, when an image is still over the size limit after being scaled down.

The guidelines below are what each network’s own API accepts. They are useful for knowing what RecurPost may adjust before publishing, rather than rules you have to meet before uploading.

TikTok

TikTok accepts photo posts as well as videos. More than one image publishes as a swipeable carousel.

  1. Format: JPEG and WebP. TikTok rejects PNG on its photo endpoint, so RecurPost converts a PNG to JPEG for you before it is sent.
  2. File Size: 20 MB maximum per image.
  3. Images per post: You can share up to 10 images in a single post using RecurPost.
  4. Dimensions: TikTok’s photo canvas is 1080 x 1920 whichever way round the image is. Very small images are scaled up, because TikTok rejects anything under roughly 720 pixels on its short edge.

Bluesky

  1. Format: JPEG and PNG.
  2. File Size: 900 KB maximum, the tightest limit of any network here. Bluesky rejects anything over roughly 976 KB outright, so RecurPost resizes to stay safely under it. The Bluesky app only appears to accept large photos because it shrinks them on your phone before uploading.
  3. Images per post: You can share up to 4 images in a single post using RecurPost.
  4. Dimensions: up to 2000 pixels wide.
