Main Causes for Unable to Upload Images on Pinterest

When trying to post images on Pinterest, the upload may stop midway, or an error message saying "Unable to process image" may appear. In such cases, it may not only be a temporary glitch on Pinterest's side but also situations where the image file or account status is the cause.

First, let’s check the following items.

• Is the image format supported?
• Is the image size or capacity too large?
• Is the image file corrupted?
• Could there be browser or app-specific issues?
• Are there any outages on Pinterest's side?

Checklist to Confirm First

• The image is in a supported format such as JPEG, PNG, or WEBP.
• On the web version, it is below 20MB.
• The image file name does not contain too many special characters.
• I tried uploading a different image.
• I tested both smartphone and PC versions.
• I checked if I could post on a new board.

Just checking from the top can resolve many upload errors.

Check Image Format and Capacity

Pinterest mainly supports formats such as JPEG, PNG, WEBP, BMP, and TIFF for image pins. Additionally, the upload limit from the web browser is 20MB.

Images edited on smartphones or saved with some image editing software may look like JPEG, but their internal format could be special.

In such cases, reopening the image and resaving it as JPEG or PNG may help.

Review Image Size and Aspect Ratio

While Pinterest allows posting images of various sizes, the recommended aspect ratio is 2:3 (1000×1500px). Extremely wide or tall images may cause processing errors or layout issues.

Users have reported that changing image size or aspect ratio has enabled them to successfully upload images.

Consider Issues Related to Browser or App

There have been reports of cases where only images cannot be uploaded, whereas videos can be posted. Additionally, some have found that uploads fail in Chrome but succeed in smartphone apps or different browsers.

Let’s try the following methods.

• Use a different browser on the PC version.
• Post from the smartphone app.
• If it fails on the PC version, try the app version.
• If it fails on the app version, try the PC version.

Changing the upload method can often resolve the issue.

Possibility of Issues on Pinterest's Side

Even if there are no problems with the image format or size, there may be temporary upload issues occurring on Pinterest's side.

In such cases, the same error may occur no matter how many times you try, but posting may become possible after a few hours to a few days. Similar reports can be found within user communities.

If you can't upload any other images either, consider that it might be an issue on the service side rather than your environment.

If You Just Want to Share Images, UploadF is Convenient

Even if you can't post to Pinterest, you may just want to quickly send the image to someone.

In such cases, using UploadF is also recommended.

UploadF is a free file uploader that can be used via browser, allowing image uploads from both PC and smartphone. It supports drag-and-drop and allows you to share multiple files at once.

Additionally, you can set passwords and have individual deletion functionality, making it convenient for sharing images temporarily.

For images, there are useful features available such as online image editing, mosaic processing, resizing, background transparency, OCR, and AI image learning prevention.

Points to Remember When Posting on Pinterest

On Pinterest, not only the images themselves but also the title and description affect search results. Moreover, using images that are close to the recommended size improves aesthetics and makes them more visible to many users.

• Use the recommended size (1000×1500px).
• Save as JPEG or PNG.
• Don’t unnecessarily inflate file size.
• Also fill in the title and description.

Conclusion

If you're unable to upload images on Pinterest, first check the image format, capacity, and size. After that, attempting different browsers or the app version can often resolve the issue.

If you absolutely cannot post to Pinterest, but your goal is simply to share images, utilizing a file-sharing service like UploadF will allow you to send images to others quickly.
