Common questions
How much will my PDF shrink?
Text-heavy PDFs typically reduce by 5-15%. PDFs with embedded thumbnails, attachments or bloated metadata can shrink by 20-40%. Image-heavy or scanned PDFs see smaller reductions as pixel data requires specialist encoding.
Will compression affect my PDF quality?
Light and balanced compression preserve all text, fonts and layout. Maximum compression strips metadata and alternate image streams — text remains readable but complex graphics may show minor changes.
Is there a file size limit?
Free users can compress PDFs up to 25MB. Pro users get up to 100MB and Business users up to 500MB.
Can I compress a scanned PDF?
Yes. ShrinkMyDocs reduces file overhead and strips metadata. For maximum reduction of scanned documents, choose Maximum compression level.
Do I need an account to compress a PDF?
No. Compress PDFs instantly without creating an account. Upload, choose a compression level and download.
Is my PDF secure when I upload it?
Yes. All files are encrypted in transit and automatically deleted after download. We never read or store your documents.
