Uploading images to Sirv

You can upload files via:

  • Browser – simply drag and drop folders or files into your account.
  • FTP – a popular method for uploading lots of folders or files.
  • S3 interface – the recommended method for secure uploads or managing files via an API.

Browser upload

All browsers support file uploads to your account and some also support folder uploads.

Browser File upload Folder upload Zip upload
Chrome Yes Yes Yes
Firefox Yes Yes Yes
Opera Yes Yes Yes
Edge Yes Yes Yes
Safari Yes No Yes
IE11/IE10/IE9 Yes No Yes

To upload a file, either drag and drop your images into your account or click the Upload button near the top left of your account.

FTP upload

To upload by FTP, enter the settings below into your FTP program. Popular programs include FileZilla (Windows/Mac/Linux), Transmit (Mac) or Free FTP (Windows).

  • FTP server: ftp.sirv.com
  • Your username: Your email address
  • Your password: same as your Sirv password
  • Encryption: plain FTP (not SFTP/TLS)

If using FileZilla, open Site Manager and setup your account like the screenshot below, then click Connect:

Multiple FTP accounts

If you manage multiple Sirv accounts, you can FTP into another account by using your Sirv email and password and appending the account name to your email address. For example:

  • yourname@example.com+otheraccount

This is how the configuration looks in FileZilla:

FTP append

Sirv supports the APPE command (append), which can be useful when uploading huge files or if your network connection is unstable. If a connection breaks during an upload, APPE makes the file continue uploading where it left off. Most, but not all, FTP programs support APPE.

To use APPE in Filezilla, go to Edit > Settings… and set the File exists action for Uploads to Resume file. Screenshot:

If you have a slow or unstable internet connection, images may not fully upload to Sirv. If Sirv receives only part of an image, the missing part will show as dark grey. You’ll see an alert in your Sirv account, recommending that you upload the image again. Simply reupload the image and it will be reprocessed.

If an unstable internet connection leads to numerous partly uploaded images, try zipping your images or using an S3 upload program.

S3 upload

Sirv supports the Amazon S3 interface, permitting you to upload, download and manage your files with a program that supports S3.

Uploads over S3 use only 1 port (443) and are secure (HTTPS). Interrupted uploads can be resumed because uploads have integrity checks (by returning the file MD5 in the ETag header). S3 also supports multipart uploads, breaking large files into smaller chunks and then building them together. These benefits make S3 an attractive alternative to FTP.

To configure S3 uploading, you’ll need your S3 credentials from your Sirv account and a program that supports S3, such as Cyberduck (Windows/Mac/Linux).

Follow our step-by-step instructions to configure Cyberduck. Once configured, set Cyberduck to repeat failed uploads, by ticking the “Repeat failed networking tasks” box:

Uploading zip files

Zip can be a useful way to upload your images.

A zip archive can contain many folder and files. Once uploaded, Sirv will unpack the zip and maintain the same folder structure.

  • If the zip file contains a single top level folder, that folder will become the root for all extracted data.
  • If the zip file contains multiple top level folders or files, all the data will be extracted into a new folder with the filename of the zip.

There is no limit to the number of folders but the tree must be no deeper than 3 folders or the zip will not self-extract. We recommend keeping zips below 5GB in size.

Sirv can detect if a zip has only partly uploaded and it can resume where it left off if the connection is broken.

Create your archives in ZIP format (.zip). Sirv cannot extract files from proprietary formats such as RAR (.rar).

Downloading images

To download files from your Sirv account, either right-click the file/folder or select multiple files/folders and click Download. Sirv will package all the files into a zip file and the download will commence.

Downloads are limited of 4,000 files and 512MB per zip file (whichever is greater). The zip will not be generated if either limit is exceeded.

You can also download files by FTP or S3 (unlimited).
