Built For E-Ink. Tuned For Every Kindle.
Most converters give you the same file regardless of where it lands. We size every page for the exact device you're sending it to, then dither and split for the way e-ink actually renders.
Per-Model Resolution
Basic, Paperwhite, Oasis, Scribe, Colorsoft. Each device gets pages sized to its exact native resolution, never upscaled or letterboxed.
Smart Dithering
Grayscale conversion tuned for 16-shade panels. Screen-tones and shadows hold their detail instead of crushing to flat grays.
Smart Splitting
Drop a 400-page tankōbon and it arrives as readable chapter-sized files, automatically split below your email provider's attachment limit.
Web App: Drag & Drop
Drop a file in your browser. Conversion runs server-side, delivery hits your Kindle in under a minute.
Desktop App: Watched Folders
Pick a folder. New files inside are converted and sent the moment they land.
3 free deliveries to get you started. No credit card required.
Drop Almost Anything.
Whatever shape your files are in, we read them. Comic archives, e-books, PDFs, or just a folder of images straight off a scanner.
- CBZ, CBR, ZIP: The standard for comic and manga archives. Cover art preserved.
- EPUB and PDF: Reflowable or fixed-layout, scanned or born-digital. We figure out which and convert accordingly.
- Image folders: Drag a folder of JPEG, PNG, or WebP files. We sort, package, and deliver.
Free to try, no credit card required.
Every File You've Sent. One Dashboard.
Your delivery history lives in the cloud, accessible from any browser. Cover art, page counts, and which device you sent each file to, all in one place. With instant search and smart status filters, you'll never wonder whether you've already sent a volume.
- Visual Grid: Cover art pulled from AniList where we can find a match, or extracted from the file itself.
- Smart Filtering: Search by title, filter by device, or jump to your most recent uploads.
- Re-deliver in One Click: Pick a file from your history and send it again, no re-upload needed (within the 24-hour window).
Pixel-Perfect Optimization.
We don't just move files. We remaster them. Every page is analyzed and tuned for the specific E-Ink display of your Kindle.
Send the Whole Stack in One Click.
Pick the files you want on your Kindle and hit "Send". We handle the rest. Large volumes are split automatically to fit email limits, and every page is sized to look crisp on your e-reader screen.
One Subscription. Two Platforms.
Use the web app for quick uploads, the desktop app for watched folders and USB transfer, or both.

Frequently Asked Questions
What is the Web App?
The MangaSendr Web App runs in your browser, with no download or installation. Drop a CBZ, CBR, ZIP, EPUB, PDF, or image file into your library and we convert it for your exact Kindle model and email it straight to your device. Works on any browser: phone, tablet, or computer.
Do I need to install anything?
No, the Web App works entirely in your browser. If you want watched-folder automation or USB transfer, the optional Desktop App for macOS and Windows handles those.
Is it free?
You get 3 free deliveries to get you started with no credit card required, plus bonus deliveries for inviting friends and completing quests. For unlimited deliveries, MangaSendr is available via Monthly ($2.99/mo) or Yearly ($24.99/yr, 3 months free) plans. One subscription covers both the Web App and Desktop App. Your library and settings are always preserved, even if you don't subscribe right away.
Which devices are supported?
Email Delivery (Kindle): Kindle Basic, Paperwhite (3+), Oasis, Scribe, and Colorsoft. Files arrive straight in your Send-to-Kindle inbox.
EPUB Download (Any Reader): Download optimized EPUB files for Kobo, Android e-ink, or any EPUB-compatible device, directly from your browser.
USB (Desktop App): Push converted files straight to a Kindle over USB, including older Kindles and Kobo devices.
Can I use both the Web App and Desktop App?
Yes. A single subscription covers both platforms. Use the Web App for quick uploads from any browser, and the Desktop App for watched folders and USB transfer. Log in with the same account on both.
Is MangaSendr providing manga content?
No. MangaSendr is a conversion and delivery tool for files you provide. We don't host or distribute content. You upload files you have the right to read, and we convert and deliver them to your devices.
What happens to my files after delivery?
They're purged within 24 hours of delivery. We keep a small cover thumbnail and the metadata (title, page count, conversion settings) so your library page still looks like a library, but the original file and the converted output are wiped. Drop the file again any time to redeliver.
Why are some volumes split?
Email providers limit attachment sizes (usually 25-50MB). Our engine splits large volumes automatically (for example, "Vol 1 Part 1") to guarantee delivery, preserving the cover image on every part.
Is Kindle email setup hard?
Not at all. It takes about 60 seconds. Just add our delivery address to your Kindle's approved email list in your Amazon settings. We walk you through each step during onboarding.
Is my data safe?
Yes. Files are processed and delivered, then purged from our servers within 24 hours. We don't hoard your library. Account data and delivery history are encrypted and private to your account.
What happens if I cancel?
Your library, devices, and delivery history stay in your account. You just won't receive new deliveries beyond any free deliveries you have left (3 to get you started, plus bonuses from referrals and quests) until you resubscribe. No data is deleted.
How is MangaSendr different from Calibre or KCC?
Calibre and Kindle Comic Converter are powerful tools, but they require a desktop install, a sequence of manual steps per file, and they don't deliver to your Kindle. MangaSendr does the conversion in your browser (or on a watched folder), tunes the output for your exact Kindle model, and emails the result straight to your device. Drop a file, get it on your Kindle in under a minute.
