Frequently Asked Questions about PDF Editing
What can I do with this online PDF editor?
You can merge PDFs, split or extract pages, compress files, add text watermarks, rotate pages, delete pages, reorder pages, add page numbers, convert images to PDF, export PDF pages as images, lock or unlock PDFs, extract embedded text, fill forms, add e-signatures, and use the visual Edit PDF workspace for text, images, highlights, shapes, signatures, and whiteout edits.
Can I type on a PDF or cover existing text?
Yes. Use the Edit PDF mode to add new text anywhere on the page, insert images or signatures, highlight sections, draw shapes, and place whiteout boxes over content you want to cover before adding replacement text.
How do I merge PDF files online?
Choose Merge, upload the PDFs you want to combine, arrange them in the desired order, and click Merge. The editor creates one combined PDF that is ready to download.
Can I split a PDF by page range?
Yes. Choose Split to enter page ranges such as 1-3 or 2,5,8. You can extract a single page, a custom set of pages, or a range of pages into a new PDF or ZIP result.
Is my uploaded PDF stored permanently?
No. PDF operations are handled only for the requested edit and the result is returned directly to your browser. We do not publish your files or keep a public document gallery.
Can I add a watermark to a PDF?
Absolutely! With our watermark feature, you can add text or image watermarks to your PDF. This is useful for protecting your documents or adding branding. You can customize the watermark position, opacity, and text.
What is the maximum PDF upload size?
You can upload PDF files up to 100MB per document. For merge jobs, you can add up to 10 PDFs with a total batch size of 200MB.
Do I need to install any software?
No software installation needed! Our PDF Editor is completely web-based. You can access it from any device with a web browser. No downloads, no installation, no plugins required.
Is the PDF Editor free?
Yes, the PDF Editor is free to use. There are no hidden charges, no forced watermarks added to your documents, and no trial period. Standard upload and batch limits apply to keep the tool reliable.
What file formats are supported?
The editor works with PDF files for editing, organizing, compression, signing, form filling, and security. It also supports JPG and PNG image uploads for image-to-PDF conversion and can export PDF pages as PNG or JPG images.
Can I sign PDF documents online?
Yes. Use E-Sign to add a signature image to a selected page, or use the Edit PDF workspace to place a signature and adjust its size before exporting the edited PDF.
Does OCR work on scanned PDFs?
The OCR Text tool extracts embedded text from text-based PDFs. If a document is only a scanned image with no embedded text layer, the tool will identify that limitation instead of pretending to return unreliable text.
Will this PDF editor work on Mac, Windows, Chromebook, iPhone, or Android?
Yes. CalculatorApp.me PDF Editor runs in a modern browser, so it works across macOS, Windows, Linux, ChromeOS, iOS, and Android without a desktop installer.
