Frequently asked questions
Why is 5MB a standard limit for many systems?
While email providers often allow up to 25MB, many corporate systems, university portals, and government application sites restrict uploads to 5MB to ensure fast loading times and manage storage costs.
Will the text in my PDF still be readable?
Yes! PDF compression primarily targets the embedded images within the document. Text streams are compressed losslessly, so your written content will remain perfectly crisp and legible.
Is it safe to compress sensitive documents?
Yes, it is entirely safe. Our tool runs locally in your web browser using WebAssembly. Your documents are never uploaded to our servers, making it completely secure for financial records, IDs, and legal documents.
