How can I merge multiple scans into a single PDF file under 3MB for my visa application?

Hi! I just got a request to add some documents to my application: all the pages of my current + previous passport (i recently renewed it because all the pages of the previous one where full).

I have been trying now for 3 hours to merge all the scans in a PDF that is less than 3MB and it looks impossible.

Please help me if you know how to do this! I am desperate.

TLDR : Answer Summary
A user seeks help to merge scans of their current and previous passport into a single PDF under 3MB for a visa application. After several failed attempts, they received various suggestions from community members, including using online tools like I Love PDF and CamScanner. One user successfully reduced their file size by converting PDF scans into JPGs, resizing them, and then merging and compressing them back into a PDF.

Thanks to everyone for the tips!!! I tell you what I did.

Compressing was not working because it is a total of 35 scans.

The process I was doing and was not working was: scan with Notes-convert into PDF-merge PDFs (adding a cover google docs explaining what is in the PDF) and then it was 17 MB. šŸ˜

Impossible to compress.

SO: I did this: take every single PDF scan and convert into JPG. Then reduce the size of each single jpg to 900px width- then take them all and convert into PDF again. Then merge into a pdf then compress it.

🤪

And it is 3MB.

All with ilovepdf.

You have no idea of the level of stress haha.

Thanks again to you all. Will keep u updated with my visa resolution and process!

I used CamScanner, scanned everything with my phone and compressed everything in a document with the ilovepdf tool on my laptop.

Great tip, technology can scare me sometimes but I just tested this and even a child could use it.

Now all I need is to get the documents in the first place but I got this aspect covered.

All your scan you can merge all via Adobe Acrobat if you don't have put in PowerPoint, change the settings of the pixels during the save as
