SendtoKindle is a lightweight ebook sender for your phone: push PDF, EPUB, TXT, DOC, DOCX, RTF and HTML files, plus images, straight to your Kindle email address. No cable, no desktop, no USB.

■ Send your first book in under a minute
1. Open Settings and enter your Kindle email address (find it in Amazon's "Manage Your Content and Devices")
2. Tap "Choose file" on the home screen — or share a file to SendtoKindle from any app
3. Check the file name and recipient, then tap Send. Sync your Kindle and the document appears

■ Features
· Supports PDF, EPUB, TXT, DOC, DOCX, RTF, HTML, PNG, JPG and GIF
· Up to 20 MB per file, with format and size checks before upload
· Send straight from the system share sheet in any app — no need to save the file first
· Local send history with file name, size, recipient, time and delivery status
· Clear error messages and one-tap retry when a send fails
· Optional custom email subject, so documents are easy to spot in your Kindle library

■ Privacy
· Our server only relays your file and deletes it right after sending — no file storage, no mailbox list
· Send history stays on your device; no account or sign-up required
· All traffic is encrypted over HTTPS

■ Before you start
· Add the sender address to your Amazon "Approved Personal Document E-mail List", otherwise Kindle rejects the message
· Use the Kindle email address shown in your Amazon account
· Supported formats depend on Amazon's Send to Kindle service; some legacy formats (such as MOBI) may not be accepted
