Share .mobi files
Share a MOBI file with anyone — just send the link
Drop your .mobi file, name the link and send it. They download the original in one click — no attachment limit, no shared-drive permissions, nothing converted along the way.
- One-click download of the untouched original
- No attachment limit, no 'request access'
- Replace it later and the same link shows the new version

Any other file or a whole website works too
Why share a MOBI file as a link?
Ebooks are made to travel between devices, but getting one onto someone else's is awkward: stores lock them in, email limits get in the way, and chat apps can't open them. A link delivers the file with one click, ready to open in their reading app.
Usually you'd be sending it to readers, reviewers, students or a book club. They don't need an account, and you don't need to know which app or device they'll open it on.

On their side
What the person you send it to sees
They tap the link and the .mobi file (Mobipocket ebook) downloads straight away, exactly as you uploaded it, ready to open in Kindle devices and the Kindle app or whatever they use for .mobi files.
What they need
- Kindle devices and the Kindle app
- Calibre, for reading and converting
- Most e-reader software, with varying support
- No account — the download starts from the link
Sending a MOBI file: link vs. the usual ways
What happens to a .mobi file when you email it, drop it in a chat or put it in a cloud drive — and what changes when you send a link instead.
Email attachment
Most mail providers cap attachments at roughly 20–25 MB, and every revision means another email.
Chat app
Chat apps can't open ebook formats, and large illustrated books exceed their limits.
Cloud drive
Drives can't preview ebooks and readers need access before downloading.
A 99helpers link
The original file, byte for byte, at a link you choose. Password it, see how often it's opened, and replace it at the same link whenever you need to.
Sharing takes about ten seconds
- 1
Drop it
Drag your .mobi file onto the box, or pick it from your computer or phone.
- 2
Name the link
Choose the words: q3-report.99helpers.site reads better than a random string.
- 3
Send it anywhere
Paste the link into an email, a chat, a document, a bio or a QR code.

What people send .mobi files for
- Ebooks distributed for older Kindle devices
- Review copies sent to readers directly
- Books converted from EPUB with Calibre
- Archived ebook libraries
Before you share your MOBI file
- Only share books you have the right to share (your own, or DRM-free and licensed for it).
- Include the cover in the file so it shows in the reader's library.
- EPUB opens on almost every device; offer it if you can.
- Use a password for advance or paid copies.
Sending the link isn't the end of it
An attachment is gone the moment you press send. A link is still yours: you decide who can open it, what it shows and how long it stays.
Fix it after sending
Upload a corrected version to the same link. Everyone who has it sees the new one; old versions are kept.
Keep it private
Add a password so only the people you give it to can open the link.
Know it was opened
See how many times the link has been visited, so you're not left wondering.
Take it back
Delete it and the link stops working — something you can't do with an email attachment.
Sharing MOBI files: questions
How do I share a .mobi file?+
Drop it on this page, choose the words for your link, and publish. You get an address like your-name.99helpers.site to paste into an email, a chat, a document or a QR code. Whoever clicks it gets the file as a download.
Does the person I send it to need an account?+
No account is needed. They click the link and the file downloads; to open it they'll need Kindle devices and the Kindle app or another app that reads .mobi files.
Can I share a MOBI file privately?+
Yes. Add a password when you publish and only people you give it to can open the link. You can also ask for a name and email before the file is shown.
What if I need to change the file after sending the link?+
Upload the new version to the same address. Everyone who has the link gets the update, and the previous versions are kept in case you need one back.
Can I share several MOBI files at once?+
Yes. Drop a folder or a .zip instead of a single file and everything goes out under one link, each file at its own address inside it. How much you can upload depends on your plan — the limits are on the pricing page.
What does the reader need to open it?+
A reading app for the format — Apple Books, Google Play Books, Kobo, Calibre or a Kindle for its own formats. The file downloads with one click and opens from there.
Sharing something else?
Want it online for good?
If the file should stay at a permanent public address — a download page, an embed, part of a site — see host a MOBI ebook.
