Compress a PDF locally with quality presets and a before-and-after size comparison.
The file is compressed on your device, and it never leaves your browser.
Use the compressor when a document is too large to attach or submit. Choose a quality preset based on how the pages will be read, then inspect the output. Image-heavy documents may benefit more than PDFs that are already compact.
Compress an image-heavy handout using the balanced preset. Compare the file sizes and zoom into small text before choosing the version to share.
Compression is not guaranteed to make every PDF smaller. This workflow can rasterize pages, affecting selectable text and document features. Keep the original and check readability.
Open the PDF you want to reduce. Choose a compression quality preset and run the process. Compare the output size and visual quality before saving the result.
