Signing Documents produces really large PDF files

[ArbiterGR]

Issue Description

When signing documents, the signed version of the document, documenso produces is really large. Around ~3-5mb for a single page, or ~16mb for a 2 pages document.

Steps to Reproduce

Complete a signing flow and observe the result file's size

Expected Behavior

The files should be as close to the original size as possible.

Current Behavior

The files produced are really large, making their storage long term an issue.

Can you provide an example PDF where this happens? I ran a few tests locally but nothing came up significantly larger on my end, there was some file size growth but that's to be expected since the certificate is attached.

Thank you for the reply. For starters, this is on a self-hosted docker based instance. I did some tests since i opened this issue. If i only sign the document, meaning no other fields set and populated, the file size grows just a little bit to include the signature image and certificate as expected.

However if i use a template for the same document which has text fields and drop down menus as well, the resulting signed pdf is huge.

Here's some test pdfs i produced for testing:

Unsigned pdf: test_pdf_unsigned.pdf / file size 414.8kb

Signature Only pdf: test_pdf_signature_only.pdf / File Size 756.4kb

Signature & fields pdf: test_pdf_signature_and_fields.pdf / File Size 5.1mb

test_pdf_signature_and_fields.pdf test_pdf_signature_only.pdf test_pdf_unsigned.pdf

Edit: Re-attached test PDFs

We are experiencing this where our documents grow to 50mb each after adding fields and signing

I am experiencing large PDFs as well. My database is 600MB with 30 completed documents.

This is still happening.

The issue is very simple to replicate - for each field (we are adding via API) the document grows at an unexpectedly large rate.
