Most "free" converters make you upload your file to their server first. That means a copy of whatever
you're converting, whether it's a photo, a PDF, someone's ID, or a document with real information in it, leaves your
device and lands on a computer you have no control over. Maybe they delete it right away like they claim.
Maybe they don't. Maybe it sits in a log somewhere, or gets swept up if that server's ever breached. You're
just trusting a stranger. Lotus Convert never asks you to make that bet. Every tool here
runs using capabilities your browser already has built in, the same rendering and decoding engine it uses
to display web pages and play videos, so your file gets converted directly on your own device. It never
leaves. You could turn your Wi-Fi off after the page loads and every tool here would still work fine.
Here's what's actually happening under the hood: image conversion uses your browser's own Canvas tool to read
the picture and spit it back out in a new format. Merging and compressing PDFs runs on a PDF library that
loads into your browser and works locally. Turning PDF pages into images uses your browser's built-in PDF
renderer. Background removal grabs a small AI model once (so after that it can run offline) and does the rest
on your device. The only thing that ever touches the network is loading the tool itself and the ads. Your
actual files never do.
Runs entirely on your device
Combine a few PDFs into one file.
Add the PDFs you want to merge, arrange them in the order you need, and download one combined file. It's all done by your browser, so nothing gets uploaded in the process.
Drop your PDFs here
.pdf files. Batch supported.
Nothing added yet. Drop a couple PDFs up top to get started.

How this actually works
Your PDFs get read straight into your browser's memory and stitched together page by page, using a PDF
library that runs entirely on your end. Once it's assembled, you get the combined file as a download. It
never passes through a server on the way.
Can I reorder the PDFs before merging?
Yep. Use the up/down arrows next to each file to get them in the order you want.
Is there a limit on how many PDFs I can merge?
Not really. Add as many as your device can handle in memory.
Can I merge PDFs without uploading them anywhere?
Yep. It all happens on your device. Nothing sent to a server, no account needed either.

About Lotus Convert
This is a small set of tools built by one woman who got tired of "free" converters that make you
upload a file just to change its format. Everything here runs in your own browser instead, so there's
no server in the middle holding your files. No huge company behind it, no investors, just something
built to work the way a tool like this should.
The site is supported by ads (you'll see them on the page) rather than accounts or subscriptions —
that's what keeps every tool free with no file limits and no watermark. See the
privacy policy for details on how those ads work.
