Combine Images into One PDF Under a Size Limit

Photograph each certificate, add them all here, and get one PDF that already respects the size limit written in your application notice.

Choose your files

Pick from your files or gallery. You can also drag a file here.

Required size

We create the highest-quality file possible within this limit.

Maximum size

Compression rebuilds each page as an image: text may no longer be selectable, form fields and links are flattened, and any existing digital signature (DSC / eSign) becomes invalid. If signature validity matters, do not modify a signed PDF.

What this tool changes

This is the two-step submission task done once: conversion to PDF and size reduction happen together, so you never have to guess how much to compress each photo beforehand.

Common upload problems

The PDF will not reach the limit: Reduce the number of pages, or photograph documents in brighter light — clean pages compress far better.
One page is sideways: Rotate the image in your gallery before selecting it.

Frequently asked questions

How many images can I add?: There is no fixed limit, but a phone may struggle beyond roughly 20 high-resolution pictures at once.
Do my documents leave my device?: No. The PDF is assembled inside your browser.
