Does this PDF compressor flatten pages into images?
No. ChopKitty targets embedded images inside the PDF and keeps the original document structure whenever possible.
COMPRESS PDF
Secure PDF Compression
Shrink huge PDF documents and manuals. ChopKitty optimizes embedded images instantly while keeping your data absolutely secure.
Why use this PDF compressor?
This page is focused on PDF compression specifically, with copy that explains the real workflow: ChopKitty optimizes embedded PDF images locally instead of flattening whole pages into screenshots.
Keeps PDF structure intact
ChopKitty compresses embedded images inside the document instead of silently rasterising every page, so text remains selectable and the exported PDF stays useful.
Skips pointless recompression
Small or already-efficient images are left alone, which helps avoid making the file larger or degrading pages that do not benefit from another pass.
Private document processing
Manuals, scans, and image-heavy PDFs are handled in-browser. That means no upload queue and no need to trust a third-party service with sensitive documents.
PDF Compression Questions
What kinds of PDFs benefit most?
Image-heavy PDFs such as scans, slide exports, and brochures usually see the biggest gains because embedded images account for most of their file size.
What happens to text-only PDFs?
If no worthwhile embedded images are found, the tool can keep the file unchanged and surface that result instead of pretending the document was compressed.
Are PDFs uploaded to a server for compression?
No. PDF compression runs locally in the browser, so the document stays on the device throughout the workflow.
