Compress PDF
Reduce image-heavy and scanned PDF file sizes locally, with honest savings and no document uploads.
How to Use
Choose a PDF, select balanced or strong compression, wait while pages are optimized, compare the result, then download.
Best Results
Scans, photos, presentations, and image-heavy PDFs compress best. Text-only PDFs may already be compact.
Related Tools
Smaller documents, private processing
Reduce large scanned documents before email, storage, or sharing. If recompression would increase the size, the tool safely retains your original PDF instead.
Frequently Asked Questions
Is my PDF uploaded? +
No. Reading, rendering, compression, and download all happen locally in your browser.
Will text remain selectable? +
Yes for text PDFs: safe mode preserves their structure. Only scan and image-only PDFs use visual page compression.
Why was my original retained? +
Some PDFs are already highly optimized. If the generated file is larger, the tool returns the smaller original.
Which level should I use? +
Balanced suits most scanned files. Strong is useful when minimum size matters more than fine visual detail.
