Об’єднувати PDF без завантаження на сервер
Merging PDFs is another task that usually sends every source file to the cloud. PDF-Snap merges entirely in your browser: add two or more PDFs, set order, download one combined file — with the same no-upload architecture as compression.
How local merge works
pdf-lib loads each document from memory, copies pages into a new PDF in the order you choose, and writes the output locally. Thumbnails in the merge flow are rendered with PDF.js in your tab — previews are not uploaded either.
Drag handles let you reorder files before confirming. That is useful when assembling scanned pages, monthly reports, or annexes where sequence matters.
Use cases
Scanned stacks: Combine separate scans into one submission. Report assembly: Cover letter + body + appendix without emailing parts to a merge service. Personal records: Bank statements or tax pages where you do not want a third party to see filenames or content.
Privacy parity with compress and split
If you already trust local compression, merge deserves the same scrutiny. One upload-based merge tool exposes every input file, not just the largest. PDF-Snap treats merge as local-only processing.

Order matters for submissions
Insurance packets, visa applications, and tender responses often specify page order. Drag-to-reorder before merging beats merging in the wrong sequence and splitting again. Preview filenames in the list so annexes are obvious.
Large merge jobs
Dozens of files can stress mobile RAM. On a desktop, merge in one batch; on a phone, consider merging in chapters then combining those outputs in a second pass — still locally, still without upload.
Split then merge workflows
Sometimes you need pages 1–3 from one export and 4–10 from another. Split locally, discard unwanted parts, merge the pieces in order — still without sending intermediates to a server. That pattern is common when fixing scanned batches.
Filename hygiene
Merge lists show filenames clearly. Rename files before upload to the merge queue if order is ambiguous. Clear names reduce mistakes in high-stakes packets.
After merging, compress locally if the combined file exceeds email limits — two local steps, zero server copies of either operation's inputs if you stay on PDF-Snap throughout.
Split is available on the same page when you need to break an oversized export before merging selected chapters only.
Accessibility and preview
Because previews render locally, screen readers and zoom behave like any other in-tab content. You are not waiting on a remote preview service that might log filenames when generating thumbnails.
Export the merged PDF and spot-check page order before sending to clients — a thirty-second review prevents costly reorder requests later.
Encrypted source PDFs may load with password prompts handled locally; merged output inherits your responsibility to distribute it securely after download.
Keep source PDFs in a single folder while merging so drag-and-drop order matches your checklist — small organisational habits prevent wrong annex ordering.
The merge tab uses the same four-second sponsored wait as compress — your files still never leave the browser during that pause.
