Why we built loopdf: no account should stand between you and your file.

We kept running into students and professionals stuck behind PDF sites that demanded an account just to download an edited file. So we built loopdf to merge, convert, sign, and compress PDFs with no sign-up and no watermark, ever.

1. 2025 Shipped
   No-signup PDF tools, done right Merge, split, convert, sign, and compress PDFs with no account required and no watermark on your file, ever.
2. Now In progress
   Sanding down the in-browser editor Most of our recent work has gone into the standalone PDF editor, so people can annotate and rework documents directly in the tool instead of round-tripping through desktop software.
3. Next Goal
   Tighter document workflows With merge, split, OCR, forms, and editing already covered, the next step is chaining these tools together so a full document workflow can happen without re-uploading between steps.

This tool is one of several products built by the same small team, under RapidFoundry. Same rules everywhere: free where we can make it free, and nothing about you sold to anyone.
