Why compress a PDF?
PDFs balloon in size when they are full of high-resolution scans and photos, and then they will not attach to an email, upload to a portal, or send over chat. Compressing rebuilds the pages at a lighter resolution, so the file drops from megabytes to something you can actually share while staying readable on screen. Pick a level depending on how small you need it: High squeezes the hardest, Balanced is the everyday choice, and Light keeps more detail. Or set an exact target in kilobytes or megabytes and the tool gets as close as it can without going over. Because compression re-renders each page, scanned text becomes part of the image, so if you need it searchable again, switch on the optional OCR step (on desktop and tablet) to add a hidden text layer back. The whole process runs in your browser, so your document is never uploaded and nothing is stored on a server.
How do I compress a PDF for free?
Upload your PDF, choose a compression level or set a target size in KB or MB, and download a smaller file. It runs entirely in your browser, so the document is never uploaded.
