Common Questions
Why do most US government portals have a 1MB file size limit?
Federal and state portals like Grants.gov and SBA.gov handle millions of documents. To prevent system lag and ensure compatibility with legacy government systems, they often enforce a strict 1MB limit for individual PDF attachments.
Is it really safe to compress my financial documents online?
Most tools are NOT safe as they upload your files to their servers. PdfXpo is different: we use WebAssembly technology to compress your PDF securely on the edge. Your sensitive financial data never leaves your device, providing bank-level privacy.
Do I need to sign up to use the 1MB PDF compressor?
Absolutely not. PdfXpo is 100% free with no account creation required. We believe essential government compliance tools should be accessible to every small business owner without barriers or data harvesting.
Will the PDF quality suffer if I compress it to 1MB?
Our intelligent compression engine preserves structural integrity. While high-resolution images might be resampled, all text, tables, and signatures will remain sharp and legible for government review and audit purposes.
Can I use this tool on my mobile phone for last-minute filing?
Yes. PdfXpo is fully optimized for mobile browsers on iPhone and Android. You can compress your documents and upload them directly to provide-side portals from your mobile device.
