Frequently Asked Questions

Why compress a PDF to 400KB?

Many government, academic, and corporate web portals strictly require uploads to be under 400KB. Compressing your file ensures it meets these size constraints for successful submission.

Will it be exactly 400KB?

Our algorithm calibrates image quality and data streams to get as close to 400KB as possible without heavily degrading the content, though the final size may vary slightly based on the original file's complexity.

Is it safe to process sensitive files here?

Yes. FileVit processes all files securely. We keep your data safe.

Do you guarantee extreme compression?

We apply standard quality reductions and metadata stripping. We do not re-encode text or perform destructive downsampling, meaning very large files might not always shrink to extremely small sizes.
