Combine PDFs into one — privately
Merging PDFs is one of the most common document tasks: stitching a signed contract onto its cover letter, combining scanned receipts for an expense report, assembling chapters into a single manuscript, or bundling a batch of invoices. Most “merge PDF” sites make you upload every file to their servers first — a bad idea when those files are contracts, statements or personal records. Mynify merges them entirely in your browser, so nothing is ever transmitted.
Lossless by design
Merging with Mynify copies each page exactly as it is — there’s no re-compression and no quality loss. Text stays selectable and searchable, images stay sharp, and form fields and links are preserved. The result is a single, clean PDF that’s byte-for-byte faithful to your originals.
How it works
- Drop in your PDFs — add as many as you need.
- Check the order — files combine top to bottom, in the order listed. Remove any you added by mistake.
- Merge and download one combined file.
Tips
- Add files in reading order so the merged document flows correctly.
- Merging a lot of scans? The combined file can get large — run it through the PDF compressor afterwards to slim it down for email.
- Need the opposite? Use Split PDF to break one document into separate files or a page range.
