themgdev is a free alternative to Sejda with a powerful in-browser PDF editor. Click existing text to edit it in place, add signatures and images, then export — without Sejda's hourly task limits.
Unlike Sejda, which uploads your document to its servers, themgdev edits everything locally in your browser, so your files stay private.

Yes. Open the PDF editor, choose Edit existing text, and click any line to edit it in place — the tool matches the original position, size, font and colour.
No. Sejda processes files on its servers; themgdev edits your PDF entirely in your browser, so it never leaves your device.
