UnderLimit PDF is a browser-based PDF compressor designed to reduce a document to a specific maximum file size for online uploads. Users can select a PDF, enter the required size limit, and download the compressed result without creating an account or uploading the file to a server. PDF processing takes place locally in the browser, helping keep document contents on the user’s device.

The tool supports PDF files up to 100 MB and 120 pages, with user-defined compression targets of up to 50 MB. It can preserve text, vector elements, forms, and links when the document allows, while using reduced-resolution visual pages as a fallback for image-heavy files. After compression, users can review the final file size, page count, savings, target status, and quality information. UnderLimit PDF is suitable for reducing PDF size for applications, government portals, school submissions, identity documents, and other upload systems with file-size restrictions.

The service does not perform OCR, guarantee every target size, preserve existing cryptographic signatures, or validate submissions on third-party portals. Users should inspect the downloaded PDF, confirm readability and signatures, and follow the requirements of the receiving platform.
