The Complete Guide to PDF Editing in Your Browser
Learn how to get the most out of ModiPDF with these detailed guides for common PDF tasks.
How to Merge Multiple PDF Files into One
Merging PDFs is one of the most common document tasks, whether you need to combine invoices for accounting, compile research papers for a literature review, or assemble a multi-section report for a client presentation.
With ModiPDF, merging is simple: upload all the PDF files you want to combine by dragging them into the upload area. The editor will display thumbnails of every page from each file. You can then drag and drop individual pages or entire documents to rearrange them in any order. Once satisfied, click Export to save the combined PDF.
ModiPDF performs the merge operation entirely in your browser. This means there are no file size limits imposed by a server, no waiting for uploads, and your confidential documents are never stored on a third-party server.
How to Extract Only the Pages You Need
Sometimes you receive a large PDF that contains more information than you need. Perhaps it is a 50-page report but you only need pages 12 through 18, or a scanned document where only certain sections are relevant.
ModiPDF makes it easy to extract the exact pages you need. Upload your PDF, then select the specific pages in the navigation panel — click a page, or hold Ctrl (Cmd on Mac) and click to select several. Delete the pages you do not need, and the remaining pages will form your new document. Export the result and you have a clean, trimmed PDF.
This approach is especially useful for legal documents, academic papers, and government forms where you often need to submit or share only specific sections rather than the entire file.
How to Convert Images to PDF
Need to convert photos of receipts, whiteboard notes, or design mockups into a PDF? ModiPDF supports JPG and PNG image formats. Simply drag your images into the upload area and they will be automatically converted into PDF pages.
You can combine images with existing PDF files, rearrange pages freely, and download a single unified document. This is perfect for creating portfolios, archiving scanned documents, or preparing image-based reports.
Because everything happens locally in your browser, even large batches of high-resolution images can be processed quickly without any upload wait times.
