Current mail export options are inadequate. Print to PDF is also not helpful. Current export options all need improvement, and a bulk export option needs to be added to the web, phone app and desktop apps:
EXPORT ONE EMAIL AT A TIME
Web only (no app or desktop option): Select and export one mail at a time. No option to select several emails or a folder. The output is an *.eml file with the filename automatically given as email subject line first then date/time stamp (real example: The eccentric investment strategy that beats the rest 2025-10-02T16_09_30-04_00.eml).
BATCH EXPORT (*.eml and *.json for each email):
Proton Bridge (paid only): Current output is totally useless to me because I have no clue what the date is nor the subject, never mind not knowing with whom I was emailing (sender/recipient). Here is a real example of an exported email filename: 0__6JeRA8qTodR1eReangQJ_HCCeumVoKhzNdQ5BFOZ2bOUYh3PxFQewMWxzhEV6_Df8EeN5iQY1IEVu6k6S1NUg==
Command line export function: Output is *.eml and *json for each individual email. Filenames are similar to Proton Bridge output. (Not sure if this is only available for Windows.) Real filenames for one email:
__aB9WlXYX8q1FkH7VihvjD1wcNWANZbegCN4zba8cUsyfjzn_JmsoSk4xHfn6TgFDeI00bVg8CxJ7i4MELIuw==.eml
__aB9WlXYX8q1FkH7VihvjD1wcNWANZbegCN4zba8cUsyfjzn_JmsoSk4xHfn6TgFDeI00bVg8CxJ7i4MELIuw==.metadata.json
REQUEST 1: Please allow bulk export of emails as *.pdf or *.eml, with or without *.json files. I would like to be able to select more than 1 email from any folder, or all emails within a folder, or even a set of nested folders (that then download with the same nested folder structure with individual emails in each folder). If bulk download is restricted to paid accounts, I think that is fair but I think we should be able to download emails as *.pdf or *.eml. If there are email attachments, they should be downloaded with the email.
REQUEST 2: Please give us the option to customize the filename for the output. We should be able to choose the order of subject and date/time (at a minimum). I need to be able to sort my emails by date, and don't have the time nor computer skills to write a program to rename each file so the date comes first. It would be nice also to have to option to add to the output filename the name/email of the person with whom I am emailing.

I have posted this in 3 export email requests; not sure which is being monitored.

You could always use the Print to PDF feature, which works perfectly as is. I think this would be wasted Dev time currently with all the other basic features which are still lacking and much needed by the Proton community.

Every time I receive a receipt for a business expense I need to convert it to PDF. I can do this in the ProtonMail app -- one click. On the web I have to do multiple annoying steps. Let's please make this easy because it's a frequent requirement. I am not interested in workarounds.

Another downside of the 'Print' > 'Print to PDF' workaround: Links no longer work.

This renders it rather useless for transactional emails:
* "Welcome. Getting started: [dead button] Contact support: [dead button]"
* "Thank you for submitting your request. See its status here: [dead button]"

So, a pdf export feature that preserves clickable links would be nice.

You can just print, and save to PDF instead of saving to printer. Supported on all major OSes/browsers

Need this one. or otherwise fix the filename sent to the pdf printer. Exporting to PDF is now taking too many steps that it is almost not worth it.

Somehow I was able to print my email to a PDF. Proton Mail web client provides a button to click to print. And I selected a Microsoft Print to PDF as a printer. Some browsers like Chrome allows you to Save As a PDF. This was important that Proton provided this Print button because the normal print functionality provided by the browser was unable to print the email correctly - most of the times - no matter the browser - or printer - has trouble printing emails with html tables in them.

But yeah, i can certainly understand the need to Export email to PDF here. So, I say yes too.

This would be very useful when we have to send screenshots of various receipts to country import customs which are many times just html emails and not constructed in a convenient A4 paper format. I don't have to awkwardly resize and try to manually stitch screenshots together, I could just export in PDF with basic options on paper format, scaling, rotation, position, offsets, margins, etc. !!! Would be really good and very speedy.

The Print->Print to PDF isn't perfect as it has some side-effects and doesn't always produce a good looking document, plus some elements are duplicated on each page and there's no way to disable this behavior in the browsers built in print dialog.

Sometimes I would just like a continious screenshot image, without it being split to kind of formal standard paper dimension, eg. like Firefox can screenshot a whole website in one huge image.

Just to clarify this once and for all on why we need this feature and why it would be helpful.

1- Like Other comments said Proton allows us to print one email at the time not multilple emails it takes forever to print a package of emails to pdf.

2- If you use the "print to pdf" option of your PC that actually prints the page of what you see not the just the email meanings its not possible to open all the emails in the same page and print them. plus the view of print to pdf is horrible.

3- For those saying that we can use a third party software or website to" print to pdf " you must know by doing so you are exposing the third party every email you print. Those "third party" actually store the files with their metadata you transmit to them there is no privacy and its a risky method specially if the email you print have sensitive data. remember why are you using protonmail to begin with.

thank you

Just print to PDF

Just print into PDF? It's a system function of any Mac.
I don't miss the feature "inside ProtonMail" (as a Mac user)

Of course, there is a workaround (but it's very painful):
1. Export E-Mail as ".eml" file.
2. Open ".eml" file with a freeware program e.g. EML Reader
3. Convert to PDF-File
4. Move PDF-File to external Archive-System
==> I find it a bit cumbersome. Don't you think so?

For archiving purposes it would be extremly useful (single e-mail to PDF-file),

I think this is not needed. You have on every OS a Print to PDF option (one way or another).

For the ones who ask for printing multiple emails to a single PDF:
1) well, just print your emails separately and use a free tool to merge your PDF files into a single one.
2) other email clients (Outlook), allow you to select multiple messages and print them bulk (again, you select as destination the "print to PDF/whatever you like as PDF" logical printer)

It already exist on the Mobile IOS app, not on the MacOS-app. I would love to have it on the Mac-OS version too!

Already exists! Although, a 'Print multiple emails to (single)) PDF' feature could be useful.
