Compress PDF
Shrink scanned and image-heavy PDFs by re-encoding every page at your chosen quality — up to 90% smaller, without uploads.
Which PDFs compress best?
Scanned documents and image-heavy files see the biggest gains — every page is re-encoded as an optimized JPEG at your chosen quality, which typically cuts scanned files by 50–90%. Text-based PDFs exported from Word or LaTeX are already efficient; compressing those may barely change the size, and the text layer becomes part of the page image. The tool tells you honestly if the result isn't smaller.
Frequently asked questions
Will I still be able to search the text?
After compression, page content is stored as a high-quality image — searching inside the compressed copy requires OCR. Keep the original if you need searchable text; the compressed version is for sharing and emailing.
How is this different from other compressors?
The compression runs in your browser — your document never leaves your device. For sensitive scans (IDs, contracts, medical results), that is the entire point.
