Frequently Asked Questions
Is there a limit on how many PDFs I can merge?+
There is no hard file count limit. The total upload size across all files must be under 20MB. For larger collections, merge in batches and then merge the results.
Will the merged PDF lose quality?+
No. TryMyPdf merges at the structural PDF level — pages are copied directly without re-rendering. Fonts, images, vectors, and text remain byte-for-byte identical.
Can I merge password-protected PDFs?+
No. Remove owner restrictions first using our Unlock PDF tool, then merge.
Can I control the order of pages in the merged PDF?+
Yes — files are merged in the order you add them to the queue. If you need to reorder pages within a single file, use the Reorder PDF tool first.
Is TryMyPdf free to use?+
Yes, merging PDFs is completely free. No account, no subscription, and no watermarks are added to your output file.
After merging, compress the result to reduce file size, or add page numbers for a professional finish.
What is Merge PDF?
Merging PDFs combines two or more separate PDF files into one unified document. The result preserves every page, font, image, and embedded link from each source file — in the order you specify. It is the most requested PDF task for professionals who handle multi-part documents daily.
When should you use it?
Merge PDFs when you need to submit multiple related files as a single attachment, such as combining a cover letter with a CV, appending supporting evidence to a contract, or joining monthly reports into an annual summary. It is also essential when consolidating research notes, invoice collections, or multi-chapter books.
How Merge PDF works under the hood
TryMyPdf uses pdf-lib, a proven open-source PDF processing library, to merge files at the binary structure level. Each uploaded PDF's page tree is read and its pages are appended sequentially into a new document. Unlike tools that flatten PDFs into images before merging, TryMyPdf preserves live text, embedded fonts, vector graphics, and hyperlinks throughout.

Tips for best results
Sort files before uploading
Arrange your files in the correct order before adding them to the upload queue. The merged PDF follows the exact upload sequence — reordering after the fact requires re-merging.
Compress after merging
Merging multiple PDFs can produce a larger combined file. Run the result through our Compress PDF tool to reduce its size before emailing — especially if source files contained high-resolution images.
Remove blank pages first
Scanned PDFs sometimes include blank separator pages. Use our Delete Pages tool to remove unwanted blanks from individual files before merging for the cleanest result.
Standardise orientation before merging
If your source files have mixed portrait and landscape pages, use the Rotate PDF tool on each file first to ensure a consistent reading experience in the final merged document.
