Browser-local PDF compression
Reduce PDF file size in your browser without uploading the document. This version compresses by re-rendering pages and is best suited to scans, image-heavy PDFs, and sharing copies.

Choose from balanced quality through maximum compression.

This version renders each PDF page to a JPEG image and builds a new PDF using the original page dimensions. It can reduce many scans and image-heavy PDFs, but it rasterizes text and vector content.
Keep the original when selectable text, links, forms, or vector graphics matter. A future structural optimization mode can be added separately so it is clearly distinguished from this page re-encoding mode.
No. Reading, rendering, JPEG encoding, and creation of the new PDF all happen in the current browser.
This version compresses by re-rendering each page, so text, vector graphics, links, and searchable text become page images.
Start with Balanced. If the file is still too large, try Smaller or Maximum.
A PDF that is already highly optimized or mostly simple text may not become smaller after raster re-encoding.
Not yet. PDFs that require a password are not supported in this version.
