How to Recompress PDF Images
- Upload the PDF with images you want to reduce in size.
- Pick a quality level (low, medium, or high).
- Click Recompress Images to re-encode the images at lower quality and download the smaller PDF.
Example
A photo-heavy PDF at 8 MB with medium quality selected might compress to around 3 MB, saving over 60% of file size. The visible quality difference is usually minimal for screen viewing.
Common Use Cases
- Reducing the size of a PDF before emailing it as an attachment.
- Optimizing image-heavy reports for web publishing.
- Shrinking a scanned document that has unnecessarily large images.
FAQ
- Will this reduce text quality? No — only embedded images are re-encoded. Text and vector graphics remain crisp.
- Why is the output sometimes larger? If the original images were already compressed aggressively, re-encoding may not shrink them further.
- Is my file uploaded anywhere? No — recompression runs entirely in your browser.
