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.

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 every tool is free without an account or per-day limits. For sensitive documents, that is the difference that matters.

Frequently asked questions
How is PDFMergely different from Sejda?+
Sejda’s online tools upload your files to its servers. PDFMergely processes them in your browser, so they never leave your device.
Is Sejda safe?+
Sejda is a legitimate, well-regarded service. Like most online PDF editors it processes your files on its own servers, so your document is uploaded over an encrypted connection and deleted after a set period per its policy. That is fine for everyday, non-sensitive files; the trade-off is that your file leaves your device, and the free tier limits how many tasks you can run. For confidential documents, PDFMergely does the same work inside your browser so the file is never uploaded, with no task limits and a live 0-byte meter to verify it.
Does Sejda store my files?+
Sejda uploads your files to its servers to process them and deletes them after a set time per its policy, so they are on a third-party server during that window. With PDFMergely there is nothing to store: your file never leaves your browser, so no server copy is ever made.
Are there daily task limits?+
No. The core in-browser tools have no per-day task cap, and no sign-up is required.
Which tools are available?+
Merge, split, compress, rotate, reorder, delete and extract pages, watermark, page numbers, protect and unlock, plus convert, crop and sign.
Does it work on mobile and offline?+
Yes. It runs in any modern mobile browser and keeps working offline after the first visit.
