Compress a PDF to 100KB or less

Many online forms, job portals and email systems reject PDFs above 100KB. ConvertzPDF reduces your file size by compressing embedded images and removing unused data, while keeping text sharp and readable. Upload your file, pick a compression level and download a smaller PDF in seconds, with no signup and no watermark.

Why is my PDF so large?

Most oversized PDFs are scans or documents with high-resolution photos. A single scanned page can take several hundred kilobytes, while a text-only page is usually just a few. Compressing the images is what shrinks the file the most.

Tips to reach 100KB

Your files are deleted automatically after processing and are never shared. You can use the tool on any device with a browser, including phones.
