Drop in PDFs, Word documents, images, or plain text, put them in the order you want, and download the result — free, with no account, no watermark, and no page counter ticking toward a paywall. ## What you can combine The merge tool accepts more than PDFs, and converts everything to PDF automatically: [Merge my files](cta) - **PDF files** — contracts, statements, scans, forms. - **Word documents (DOCX)** — no need to open Word and export first. - **Images (PNG, JPEG)** — each image becomes a full page, which is exactly what you want for photographed receipts, IDs, or proof-of-damage photos. - **Text, Markdown, HTML, and RTF** — notes and simple letters convert to printable pages. Mix them freely: a DOCX cover letter, a PDF contract, and three JPEG photos merge into one document in one pass. ## How to merge PDFs in four steps 1. **Open the tool** at [postalform.com/merge-pdfs](/merge-pdfs) — nothing to install and no account to create. 2. **Add your files** — drag them in together or one at a time. 3. **Put them in order** — move files up or down until the sequence is right, and remove anything you added by mistake. 4. **Download or mail it** — save the merged PDF to your device for free, or send it straight into PostalForm's mailing flow to have it printed and delivered as a real letter. ## Need to fix something after merging? Merging is rarely the last step. A combined packet usually needs a signature, today's date, or one corrected line before it goes out. That's built in: open the merged result in the [free PDF editor](/free-pdf-editor) to add text, draw a signature, stamp an image, or fix a printed line — then download or mail the finished version. You can also [split a PDF](/split-pdf-online) back into separate files if you combined too much. ## Why merge and mail belong together Most of the documents people merge exist because someone else demands a complete packet on paper: courts, landlords, insurers, credit bureaus, and government offices. The usual workflow is merge online, download, find a printer, buy an envelope and stamps, and stand in line at the post office. PostalForm exists to delete that second half. After merging, click mail, enter the addresses, and see the exact price before paying — printing, envelope, and postage included, with Certified Mail and tracking available when you need proof it arrived. Merging and downloading are free; mailing is the only paid step. ## FAQs - **Is the merge tool really free?** Yes — combining files and downloading the merged PDF are free, with no account, no watermark, and no file limit beyond what your browser can comfortably handle. You only pay if you choose to mail the result. - **Do my files get uploaded to a server?** No. Files are combined in your browser and leave your device only if you choose to mail the merged document through PostalForm. - **Can I merge Word documents and images with PDFs?** Yes. DOCX, PNG, JPEG, text, Markdown, HTML, and RTF files are converted to PDF automatically and merged in the order you set. - **Can I change the page order?** You can reorder the *files* before merging, and afterwards you can open the result in the PDF editor to reorder, rotate, or delete individual pages. - **Can I edit the merged PDF?** Yes — add text, sign, stamp images, or fix printed lines in the free PDF editor before downloading or mailing. ## Related - [Free online PDF editor](/free-pdf-editor) - [Split a PDF into separate files](/split-pdf-online) - [Edit a PDF without Adobe](/edit-pdf-without-adobe) - [Mail a PDF online](/mail-pdf-online) - [Certified Mail online](/certified-mail-online) ## Ready to send it?
