What is the free limit?

On the free plan, you can perform 3 actions per day. Pro gives you unlimited usage.

What is the maximum number of files?

You can add up to 20 PDFs at once. The daily action quota is limited on the free plan; Pro removes the daily limit.

Chrome, Firefox, Safari, Edge, and all modern browsers are supported.

Is there a file size limit?

On the client side, files above roughly 25 MB per file may cause issues. For very large files, try splitting them first.

What this tool does

PDF merging combines reports, invoices, or lecture notes into one file so sharing and archiving are simpler. CodeGrid Tools runs the merge in your browser whenever possible, which means your documents are not kept on third-party servers like many classic cloud mergers and aligns better with privacy expectations. No install is required; use the Turkish UI to queue files and download the result. File-handling tools include a free daily quota; Pro unlocks unlimited merges and an ad-free experience.

Secure. Secure processing
