A Sejda alternative that keeps your files on your device
Sejda’s online editor is well made, but, like other web PDF tools, it uploads your documents to its servers to work on them, and the free tier caps how many tasks you can run. PDFMergely takes a different route: the same common tasks run locally in your browser, so your file is never transmitted, and there are no daily task limits on the core tools.
PDFMergely vs Sejda
| PDFMergely | Sejda | |
|---|---|---|
| Where files are processed | On your device, in the browser | Uploaded to Sejda’s servers |
| Files leave your device | Never | Yes, on upload |
| Works offline | Yes, after the first visit | No |
| Sign-up to use core tools | Not required | Required for some features |
| Core tools (merge, split, rotate…) | Free | Limited free tier |
| Best for | Private and sensitive documents | General everyday use |
Why switch?
PDFMergely moves the code to your file instead of moving your file to the code. The engine runs in your browser, there is no upload endpoint, and the core tools are free without an account or per-day limits. For sensitive documents, that is the difference that matters.
Every PDF tool you need
All free, all private. Each tool runs locally in your browser, nothing is ever uploaded.
