Common questions
- Are my documents uploaded anywhere?
- No. The files are read and joined inside your browser, on your own device. Nothing is sent to Bidkoo or to anyone else, so it is safe to use for turnover certificates, PAN and bank documents.
- Why merge PDFs for a tender?
- Procurement portals usually give one upload slot per requirement, for example one file for all experience certificates. Scans come as separate files, so they have to be joined into one PDF, in the order the tender asks for, before uploading.
- Does merging reduce the file size?
- No. The merged file is about as large as the files that went into it. If a portal has a size limit and the scans are too large, rescan at a lower resolution (150 dpi in greyscale is usually enough for certificates) and merge again.
- Why was a file refused?
- Password-protected PDFs cannot be merged; remove the password first. A file can also be refused when it is damaged or is not really a PDF, for example an image that was renamed.
