Browse FilesWhen PDF compression is the right move
This tool re-renders each page as a JPEG at the quality you choose, then assembles a smaller PDF in your browser. It works best for scanned pages and photo-heavy documents.
Benefits: Tune size vs. clarity, see savings instantly, no uploads, and local browser processing.
Best for: Email attachments, portal uploads with file size limits, scanned documents, and presentations.
Limitations and tradeoffs
- Compression is image-based, so selectable/searchable text may be lost in the output.
- Line art and small text can become blurry at very low quality settings.
- This method is optimized for scanned/image-heavy PDFs, not vector-native PDFs.

How much can I reduce the file size?
Typically 50-90% reduction is possible, depending on PDF content and your chosen quality setting. Scanned documents compress more than text-heavy PDFs.
Will text still be selectable after compression?
This tool converts pages to images, so text will no longer be selectable or searchable in the output. For text-heavy PDFs, use a lower quality setting to minimize file size while keeping readability.
Is there a file size or page limit?
No artificial limits. Processing speed depends on your device and the number of pages.
