Frequently Asked Questions
How do I compress a PDF under 1MB?
Simply drop your document into the workspace above. Our engine removes unneeded object streams, strips bloated metadata, and compresses embedded images until the file size drops below 1MB (1,048,576 bytes).
Will compression remove vector graphics and fonts?
No. Vector line art, fonts, and hyperlinks are fully retained. Only uncompressed raster image streams and redundant metadata tags are resized.
Can I compress 50MB+ PDFs to 1MB?
Yes, as long as the document does not contain an excessive number of high-res image pages that cannot be downsampled further without severe blur.
Is this 1MB PDF compressor completely free?
Yes. PDF Tools Ai offers unlimited free PDF compression with no watermarks, no registration, and no software installations.
