What this compression does
Each page is rendered as an image and rebuilt into a lighter PDF.
This is often effective for scan-heavy PDFs, photo-heavy exports, and bulky print-style documents.
It may reduce text selectability or searchability because the output becomes image-based.

Why people come back
Upload limits and email attachment caps keep making this problem come back.
Preset-based compression is faster than guessing export settings in desktop software.
Everything stays local, which matters for contracts, invoices, IDs, and internal documents.
Strong first-use cases
Compressing scanned PDFs before uploading to a portal with strict size limits.
Shrinking photo-heavy documents for email attachments and client sharing.
Creating a lighter version of a bulky PDF without leaving the browser.
Practical notes
Scan-heavy PDFs usually benefit the most from this kind of compression.
Text-based PDFs may get less dramatic size savings and can lose searchable text in the compressed copy.
Balanced preset is usually the right first try before pushing all the way down to smallest file mode.
