Multipart Uploads only handles files larger than 10 MB. We set the limit because uploading files smaller than 10 MB in multipart mode does not provide any significant performance improvement over Direct Uploads.
By default, Uploadcare won't treat files larger than 100 MB as images regardless of the upload method. However, this limit can be adjusted on a per-project basis upon request.
Multipart Uploads for images will also work with Uploadcare Widget since it's an Upload API client. Keep in mind the threshold after which files get uploaded in the multipart mode is controlled via the Multipart Minimum Size option which defaults to 25 MB.
Have fun with larger images and drop us a line in case you have any questions.
Since March, we've changed our file backup mechanics. On a daily basis, we used to check your backup bucket and copy all the stored files that were missing. From now on, files only go to your backup once. And that's when they get stored. In the first case, files you've deleted could reappear. Currently, deleted files won't be restored automatically. However, you can always contact us to restore stuff you accidentally deleted.
Since we're no longer listing through your buckets, the number of respective requests lowers: your backup procedure gets much faster and cost effective.
Until quite recently, the largest image we could get from Instagram was 640x640 px in size. From now on we try to get the hi-res (1080x1080 px) images first and fallback to the standard size in case we fail.
For a good while, there was a limitation on which S3 buckets could be used for backup and as custom storage with Uploadcare. We're happy to announce Uploadcare now supports all the AWS regions (including Frankfurt, Seoul, and Mumbai).
If you're interested in the details, the problem was with AWS signature version 4.
We've added the "auto-copy" feature to your custom storage S3 buckets. After it's enabled you no longer have to send explicit requests to our REST API in order to copy uploaded files. You can still use the REST API if you'd like to copy file variants/versions.
The feature is free and is available for all of our clients that use custom storage.
We get DPI from format attributes if they exist, otherwise from EXIF
We've added an extra security option to our Upload API, with it you'll have full control of who and when can upload files to your project. The setting is project-wide and requires to have a secure signature generation on your back-end (see example in the docs).
It's natively supported by the widget starting from version 2.9.0.
