Compress PDF — Frequently asked questions
Is Compress PDF free for students?
Yes. No software to install — works on lab computers, Chromebooks and phones. There is no signup, no trial and no watermark on your files.
What kind of files can students use Compress PDF for?
Compress PDF works with the documents students handle every day — lecture notes, research papers, assignment PDFs, scanned textbooks, thesis chapters and study guides. A common case: Submitting assignments before a deadline when the upload portal only accepts one PDF under a strict size limit.
How much smaller will my PDF get?
Image-heavy or scanned PDFs often drop by 50–90%. Text-only files shrink less because they are already light. The result depends on what is inside the file.
Will the text stay sharp after compression?
Yes. Text stays crisp and searchable; compression mainly optimises the heavy images that bloat the file.
How do I compress a large PDF to email it or share on WhatsApp?
Email often rejects large attachments. Upload your file, pick a higher compression level, and you get a much lighter copy that sends easily via Gmail, Outlook or WhatsApp.
Can I compress a PDF to under 1 MB?
In most cases yes. The higher the compression level, the smaller the result; scanned, image-heavy PDFs shrink the most.
Does compressing a PDF delete pages or content?
No. All pages and content stay intact; the tool only reduces the data size — mainly images — without removing anything.
What is the largest PDF I can compress?
You can compress files up to 100 MB at once, which covers most documents, books and scanned presentations.
