Firefox PDF editor

Edit PDFs in Firefox with local browser workflows.

Slay PDF runs from the web and keeps common PDF edits in the browser, which makes it useful when Firefox is your everyday workspace.

No desktop suite

Open Slay PDF in Firefox instead of installing a heavy PDF editor for common jobs.

Local workflow

Common edits and exports run in this browser without a Slay PDF app-server upload.

Practical tools

Merge, split, reorder, sign, redact, OCR, resize and export PDFs.

A Firefox-friendly workflow for everyday PDF cleanup.

Firefox users often need a quick PDF editor for page cleanup, visual signing, redaction, form work, OCR or selected-page export.

Slay PDF is built for those practical jobs. Use a managed enterprise tool when policy, certificate signing or compliance controls require one.
