Merge Client Financial PDFs, Processed on Your Device
Direct answer
Combine statements, invoices and supporting records into one file. The merge runs in your browser, and you check page order and content before the file goes to the client.
Why this page exists: privacy by architecture, not policy
Files are merged locally. Merging can flatten form fields and may drop bookmarks or annotations, and BytesPDF does not certify the output for audit or tax purposes.
Accounting packs often mix bank statements, receipts and signed forms. BytesPDF merges the selected files in your browser, so they are not sent to our servers. Merging creates a new file and leaves the source PDFs unchanged. Check the page count, the order and the readability of every page before you send the result.

Before You Send a Merged File
Use these checkpoints with the destination's current instructions. Requirements can vary by account, institution, region, document type, and workflow. BytesPDF does not verify or guarantee recipient acceptance. Page reviewed . See the browser-local processing architecture.
| Portal / Recipient | Requirement / check |
|---|---|
| Page order and completeness | Check every page count and sequence against the source files |
| Form fields | Fields are flattened when merging: values stay visible but can no longer be edited |
| Bookmarks, annotations and attachments | These may not survive a page-copy merge; keep the source files |
| Signed documents | Signed PDFs are refused, because rewriting them would break the signature |
| Recipient or portal size rule | Confirm the limit before sending; compress separately if needed |
Which Compression Mode Should You Pick?
Three modes — pick based on what the recipient needs to do with the file.
✅ Merge — keep the source files
Merging creates a new file and leaves your source PDFs untouched. Keep the originals as the record of what was sent.
🟡 Merge limits on desktop and mobile
Desktop: up to 20 files and 150 MB combined. Mobile: up to 10 files and 50 MB combined. Larger batches are better split into several merged files.
🔴 Compress after merging only if needed
Compression can reduce image resolution. Statements and receipts with small print should be checked at 100% zoom before the compressed copy is shared.
Before compressing a high-stakes document
Compression rewrites the PDF. BytesPDF rejects files containing a cryptographic signature because any rewrite would invalidate it. Keep digitally signed files and required PDF/A archival masters unchanged. Bookmarks, links, forms, annotations, accessibility tags, and color profiles are preserved where the PDF library can retain them, but always inspect the downloaded copy before filing or submitting it.

Drop your file in — the compressor runs in this tab, so nothing is uploaded. Combine statements, invoices and supporting records into one file. The merge runs in your browser, and you check page order and content before the file goes to the client.
