Best for scanned and image-heavy PDFs
This browser compressor renders each page as a JPEG image and rebuilds the PDF. That can significantly reduce scanned documents or photo-based PDFs.
Because pages are flattened into images, selectable text, links, form fields, vector quality and accessibility information may be lost. Text-only or already optimized PDFs may become larger instead of smaller.
Use this tool for copies of documents, not your only original. For important legal, accessible, searchable or fillable PDFs, keep the original file.
