Frequently asked questions
How do I compress a PDF to 5MB?
Upload your PDF, click the "5 MB" preset, and tap Compress. Our binary-search compressor finds the highest quality that fits under 5MB — entirely in your browser, no upload.
Why does a portal want a PDF under 5MB?
India’s Income Tax e-filing portal, many university application sites (Common App attachments), and large corporate email systems cap uploads at 5MB. Going over blocks submission or bounces the email.
Will my long multi-page PDF still be readable at 5MB?
Yes — 5MB easily fits 50-200 pages of mixed text and images at high quality. The tool only reduces image DPI as needed and keeps text vector-perfect.
Is my PDF safe during compression?
Yes. ExactPDF runs entirely in your browser. The file never leaves your device — verifiable in DevTools → Network.
