An iLovePDF alternative that doesn't upload your file
iLovePDF, Smallpdf, and most similar sites work by uploading your document to their servers, doing the work there, and sending it back. That's fine for a lot of files — but not for a contract, a tax form, or anything you'd rather not hand to a third party even briefly. PDF300 does the same jobs, but most of them run right in your browser instead.

What runs locally vs. what doesn't
Merging, splitting, compressing, rotating, cropping, watermarking, signing, redacting, and converting to image or text all happen on your own device — the file never leaves it. A few heavier jobs (OCR on scanned pages, unlocking a password, repairing a broken file) still need a server, and those are marked clearly so you know before you upload anything.
Why this is worth checking before you upload
- No account, no email address, no "sign up to download" wall.
- No file size gate that pushes you toward a paid plan.
- Nothing kept afterward — there's no server copy to worry about deleting.
Common questions
Is it really free, or is there a catch?The browser-based tools (merge, split, compress, rotate, and the rest) are free with no daily limit. There's no premium tier gating basic PDF editing.
How is this different from iLovePDF or Smallpdf?Those services process files on their servers by design — that's how the tool works, not a flaw. PDF300's browser tools take a different approach: the processing runs in JavaScript on your device, so the file has nowhere to go.
What about OCR or removing a forgotten password?Those specific tools need a server because of the computation involved, and PDF300 says so on those pages rather than pretending otherwise. Everything else stays local.
