Common upload problems this solves

Documents are uploaded in separate files

Merge them only when the portal provides one combined upload field.

Pages appear in the wrong order

Arrange certificates and supporting pages before starting the merge.

The combined PDF is too large

Run the merged result through Compress PDF and verify that text and seals remain readable.

Privacy and file handling

This tool uploads each PDF to the processing service so the files can be combined. Files are processed automatically and removed from processing storage after the configured one-hour retention period. Do not upload documents you are not authorized to process.

Frequently Asked Questions

No. Merge documents only when the form asks for one combined PDF. If the portal has separate fields for a photograph, signature, marksheet, or certificate, upload each file separately.
The merge operation combines the source PDFs without intentionally applying image compression. Still, open the final file and inspect text, seals, signatures, and page orientation before submission.
Use the Compress PDF tool after merging. Strong compression can affect scan clarity, so compare the result with the portal limit and inspect every required page.
Yes. Use a supported mobile browser, select the PDFs from the Files app or device storage, arrange them, and download the combined file.
Convert the images with JPG to PDF first. You can then merge the generated PDF with the rest of your documents.
