Merge PDFs and Fit Them Under a Size Limit

The real submission task in one step: join your documents and hit the maximum size the portal allows, without running two separate tools.

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

Apply this limit

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

First the documents are combined, then the combined file is rebuilt at the best readable quality that fits your limit. You see the page count and the final size before downloading.

Common upload problems

The limit could not be met: We give you the smallest readable version and say so plainly. Removing optional pages is usually the fastest fix.
Some pages look softer than others: Photographed pages compress less predictably than clean scans. Retake the darker pages in better light.

Frequently asked questions

Why not just merge and then compress separately?: You can, but two tools mean two waits and two downloads. This page performs both and validates the result once.
Is anything uploaded to a server?: No. Both steps happen in your browser.
