Edit PDF Files Online - Secure & Private

Add text, draw freehand annotations, place rectangles to mask/redact content, highlight areas, and extract text via OCR. Full toolbar with undo/redo.

Yes. The mask tool places solid rectangles over content. Once exported, the underlying text is gone — not just hidden, actually removed from the output.

Yes. OCR runs locally via Tesseract.js WebAssembly — no server calls. Works on scanned documents and image-based PDFs.

No. The entire editor runs in your browser. Your file stays on your device, making it safe for confidential documents.

You can add new text overlays and mask existing text. Direct inline text editing of existing content is not supported yet.

PDFs up to 100MB. Large PDFs with many pages may take a moment to render but will work fine.

Yes. Navigate between pages, annotate each one, and export the entire edited document as a single PDF.

MiOffice covers annotations, masking, text overlay, and OCR — free, no account, runs locally. For heavy text reflow editing, Acrobat is still more capable.

You can add text overlays on form fields. Native form field filling is supported for interactive PDF forms.

Yes, but the editor experience is best on desktop or tablet due to the toolbar and precision needed for annotations.
