How to Download Attachments From a Roundcube Account

Shaks George · May 22nd, 2026 · How to · 5 Min Read

Need every Roundcube attachment saved to a local folder? You are in the right place. This guide shows two safe ways to extract attachments from Roundcube Webmail. One is a manual one by one route. The other is a bulk method that handles thousands at once.

Roundcube is a popular browser based mail client used by web hosts and small business mail providers. Saving attachments locally helps you keep records, free server space, and share files offline.

Overview

Roundcube does not offer a bulk attachment download button. The native route saves one attachment per click. For large mailboxes, a dedicated extractor pulls every attachment in one run. This guide covers both routes step by step.

Why Download Attachments From Roundcube?

Free Roundcube server space by pulling heavy files locally.
Keep records of contracts, receipts, and signed forms.
Share single files without forwarding the full email.
Comply with legal hold and audit needs.
Move attachments to cloud storage like Google Drive or OneDrive.
Back up images and PDFs from years of mail history.

If you also need to download multiple attachments from Office 365 or save email attachments from Thunderbird, the same approach applies across clients.

Common Use Cases and Errors

Bulk save fails: Roundcube has no built in bulk download for attachments.
Inline images lost: Manual save skips inline images on some Roundcube themes.
Large mailbox: Mailboxes with thousands of mails take days to handle one by one.
Filename clash: Two attachments with the same name overwrite each other.
Folder mismatch: Attachments from sub folders need separate visits.
Server timeout: Large attachment lists time out during long Roundcube sessions.

Manual vs Automated Method

Quick Side by Side

Speed: Manual saves one file per click. Automated handles thousands per minute.
Bulk: Manual cannot batch. Automated runs full folders in one pass.
Naming: Manual can overwrite. Automated auto names by subject and date.
Filters: Manual offers none. Automated filters by sender, date, and file type.
Folders: Manual visits each one. Automated reads every folder in one job.
Inline images: Manual can drop them. Automated keeps every embedded image.

Manual Method From Roundcube Webmail

This works for a few attachments at a time.

Sign in to your Roundcube Webmail account.
Open the folder that holds the email with the attachment.
Click the email to open it in the right pane.
Scroll to the attachment section at the bottom.
Click the small download arrow next to each attachment.
Save the file to your local folder.

Repeat for every mail. This route does not scale beyond a few dozen attachments.

Automated Method for Bulk Extraction

The Corbett Email Attachment Extractor downloads every Roundcube attachment in one run. It reads the full Roundcube mailbox over IMAP. Folder names, dates, and sender info stay intact. Filters by file type, date, sender, or size are built in.

The same app also helps you extract all attachments from Yahoo Mail and download Outlook attachments all at once. It runs on Windows 11, 10, 8, and 7.
