Frequently Asked Questions
Is the PDF compressor free? Do I need to sign up or create an account?
100% free, no signup, no watermarks, and no daily compression limit. Reduce PDF file size online without any account — just upload and download.
Can I compress a PDF to 1MB or 100KB online for free?
Yes. Choose Extreme mode for the smallest possible file size (40–70% reduction). Use the Recommended mode for a balance of size and readability. Preview the output size before downloading.
Is this a free SmallPDF, Adobe, or iLovePDF alternative?
Yes — MinifyCloud compresses PDFs like SmallPDF, Adobe Acrobat Online, and iLovePDF, but with no signup, no 2-task daily limit, no watermarks, and no file size restrictions on the free tier.
Does compression affect PDF text and image quality?
Recommended and Light modes keep the document fully readable with minimal visible change. Extreme mode strips metadata and downsizes images — ideal for email attachments and archiving where size matters most.
Can I compress a scanned PDF or image-heavy PDF?
Yes. All PDF types are supported including scanned documents and image-heavy PDFs. Extreme mode works especially well on these — image compression is where the biggest file size reductions happen.
Is my PDF file kept private after uploading?
Yes — your file is processed securely and automatically deleted from our servers within 1 hour. We never store, share, or analyse your document content.
