This is a very basic function that should have been implemented by now. Seems like most Protonmail users would have a use for this feature.

Integrate Proton mail and drive (and photos), to send and save photos and files, without downloading them first on computer/phone.

I want to mail a photo, uploaded from proton Drive and visa versa, save photo's or files attached, on the drive directly.
Proton Mail (desktop app) has exces to the Proton Drive (and also Photos) directly, to attach or link photos and files.

I can’t attach files directly from Google Drive. Are you serious?

Highly agree. Automatically making any mail attachment over 24mb into a Proton Drive link in-place is a great feature too.

Currently, Proton Mail and Proton Drive operate as separate applications with limited integration. Users who wish to share files stored in Proton Drive via email must manually navigate to Proton Drive, create a shared link, copy it, and paste it into an email. This workflow is time-consuming and disrupts productivity.
We propose an integrated feature that allows users to:
Search and access Proton Drive documents directly within Proton Mail.
A built-in search bar or “Attach from Drive” option in the compose window.
Ability to search files by name, type, or recent uploads.
Attach or share Drive documents seamlessly.
Option to attach the file directly (respecting size limits) or insert a Proton Drive shared link automatically.
Maintain end-to-end encryption and access control (e.g., password protection, expiry date).
Unified Search Experience.
Extend Proton Mail’s search to include Proton Drive files, enabling users to locate both emails and stored documents from a single interface.
Benefits
Streamlines workflow between Proton Mail and Proton Drive.
Saves time and reduces manual steps when sharing files.
Enhances usability and encourages broader Proton ecosystem adoption.
Aligns with Proton’s privacy-focused mission while improving productivity.
Example Use Case
A user drafting an email needs to attach a previously uploaded PDF stored in Proton Drive.
Instead of opening Proton Drive separately, they can:
Click Attach → From Proton Drive.
Search for “Invoice_March2025.pdf.”
Choose to Attach as File or Insert Secure Link.
Send the email — all without leaving Proton Mail.

Adding the option to attach emails from Proton Drive would be great, avoiding the need to download Proton Drive and then manually add it to the email. Ideally, the sidebar, like the calendar, would include Proton Drive, or next to the attachment icon, it would have an "Attach from Proton Drive" option.

pleeeeaaaaase, do it!

Link proton mail and proton drive so that we can:
- while writting an email, pick a file directly from proton drive to attach it in the mail or share it via a link (exactly as it work between gmail and google drive)
- detach a file attached to a received email directly in proton drive

+1 for this function - would be super useful to have this ability.

Seeing Lumo having direct integration with Drive convinced me that this is something definitely needed.

Please consider this integration

Need this desperately, especially since lumo, which they just released, integrates with drive.

THIS!!! Sure wish they'd put this on the fast track!

How is this still not a thing?

Be able to save attachments (ie photos, videos, files etc.) from Proton Mail to Proton Drive

Be able to attach files in Proton Mail from Proton Drive

Be able to send files larger than 25MB

Make this all available for Proton Free users too!!

This seems like a non-negotiable to me. Basic integration & functionality to aid workflow & match efficiency of more mainstream solutions.

Hi, 2277 votes, feature requested 2+ years and no updates!?
Is there another way to bump this feature? Do you even monitor the site?

It is difficult to understand that this has not been implemented. Privacy is great, basic integration between Proton apps would be appreciated.

I would really love a "one stop shop" of an integrated calendar, mail, drive, (proton docs and standard notes too!)

I can only repeat my previous comment: As we integrate Proton more and more into the organization, this becomes an increasing challenge. So I would appeal for a quick solution and now it is even more urgent.

Plus an option to allow email attachments to be saved automatically in a Proton Drive general default file inbox (folder), and a specific drive file folder per email sender.
