Merging matters most when a form asks for a single attachment and you have four.
An application with a photo, an ID copy, a mark sheet and a certificate is four
files; almost every upload box wants one. DesiDocs joins them in the order you
choose and hands back a single PDF.
Order is the whole job
Drag the files into the sequence you want before you merge. This is worth thirty
seconds of attention, because the order in the list is the order in the output,
and the usual mistake is uploading in whatever order the file picker returned
and discovering the annexures sit ahead of the covering letter.
Every page keeps its own size and orientation. An A4 letter followed by a
landscape scan stays exactly that — DesiDocs does not stretch or rotate pages to
make them uniform, which would distort the scan. If you want them consistent,
rotate or crop first, then merge.
Limits
- Up to 5 files in one merge.
- 25 MB per file, and 100 MB across the whole batch.
- PDFs only. To bring photos in, run them through
JPG to PDF first and merge the result.
If a file is password-protected, remove the password with
Unlock PDF before merging — an encrypted file cannot be read
into a new document while it is still locked.
Nothing is kept
The merged file is built on our servers and the uploads and the result are
deleted within 30 minutes by an automated job. No sign-up, no watermark, no
limit on how often you do it.
