Good to know

Preserve text & links optimizes streams and embedded images without rasterizing pages. If that result is larger, the original is returned. Flatten to images is an optional method that removes text and interactive features. Keep signed originals.

A PRACTICAL GUIDE

How to compress pdf under 5 mb

This page checks a 5,000,000-byte target after optimization. SARS guidance lists a 5 MB limit for supporting documents; check the requirements shown in your own submission flow.

Choose a PDF and keep Preserve text & links selected.
Run compression and read the exact output-size message.
If it is still too large, split the document into permitted parts or use the optional flattened mode after reviewing its limitations.

Prepare for SARS eFiling

Retain all requested pages and keep them readable. Password-protected or encrypted submissions may be rejected. This tool does not submit to SARS or determine whether a document meets a tax requirement.

Some files cannot shrink enough

Already-compressed scans may remain above the limit. Lower image quality in flattened mode can help, but it removes searchable text, links and form fields. Splitting may be a better choice when multiple documents are accepted.

Does conversion replace the original?

No. Each result is a new file. Compare it with your original before you use or submit it.
